SuperEdit can save the printout in HTML format. Enter Print Preview command and select DWM Publish HTML option. SuperEdit will ask for HTML file name for preview page. It will automatically create additional files containing preview image, full resolution image and pages suitable for printout.

The preview HTML page can be created from a template. The template is an ordinary HTML file, which can be created with any suitable HTML editor. It should contain special codes that will be replaced during execution of the Publish HTML command.

$$PreviewGIF$$ - will be replaced by a file name of the preview image

$$PreviewHTML-96$$ - will be replaced by a file name of the HTML page suitable for printing (when the user uses small screen fonts)

$$PreviewHTML-120$$ - will be replaced by a file name of the HTML page suitable for printing (when the user uses large screen fonts)

For successful printing HTML check for proper margins. Right click on document in Print preview window and select Margins setup. In Margins dialog set margins to 1 cm or more. Now if you want to print HTML document from your Web Browser select Print Setup and set margins for values you set in SuperEdit or a little bit more.

Printing to HTML has been tested with Microsoft Internet Explorer 4.0 and Netscape Navigator 4.06.

This command starts scanning of a single-page document.

Depending on the type of the selected scanner it may be necessary to start scanning physically, e.g. by pressing a button on the scanner. Some scanners can start scanning automatically; others can display their proprietary window with information about scanning progress. The scanned document is then displayed in a window labeled with a temporary name, e.g. SCAN_1.

This command starts scanning of a multiple-page document.

The process of multiple-page scanning is similar to the single-page scanning. After each page the dialog box appears and informs about the number of pages scanned so far. Four buttons are available (some of them can be disabled, depending on the situation):

The first page of the scanned document is displayed in a window labeled with a temporary name, e.g. SCAN_1.

The Window tab is used to determine which rectangular area of the current document will be rasterized, and what scale and what kind of units is to be used. You can choose one of the following options:

The Resolution tab is used to specify raster image resolution and to verify its size. To change resolution, select the Resolution combo box and choose appropriate value. Choose the Custom option if required resolution is not shown on that list. Then enter the required value using X dpi and Y dpi edit fields.

Calculated physical image width and height may be shown in inches, millimeters or in pixels, as selected in the Image size units combo box.

The Color tab is used to determine color type of the created image. You can choose between black and white, gray scaled or color palette images of different depth, or choose a true color image.

The Load vectors button allows you to load calibration vectors from a CAV file to which they were previously saved. Practically, the calibration vectors may be re-used only if applied to exactly the same image for which they were defined.

The Save vectors button allows you to save calibration vectors to a CAV file for further usage. The file format is ASCII. The file extension is CAV. The coordinates are listed in units defined for the raster image being calibrated (see Raster Image Properties dialog), so you cannot re-use the CAV file if you change the image units.

The Save report button allows you to save calibration report in a file with the extension REP. The calibration report includes: date, time, the name of calibrated raster file, the calibration area, the name of calibration model used, the mean square length of requested correction vectors, the mean square calibration error and the list of correction vectors. Three points describe each correction vector in the calibration report: point to be corrected, its requested position and its position after calibration.

The Add free vectors button is used to define correction vectors one by one manually. First, enter a raster point to be corrected. Choose visible detail on raster data, which nominal coordinates are known, point it, and click the left mouse button. Use Raster Snap and Magnifying Glass when appropriate. It will become the starting point of a new correction vector. Then you enter target position for this point. Enter desired coordinates numerically using Input bar. It will become the ending point of the correction vector. After entering these two points, the new correction vector is displayed as a Requested vector arrow (default red).

The Add free vectors button is automatically activated after the Calibrate raster command starts, so you may immediately start defining free correction vectors. During defining each vector, you may use the OTM Reject option if you want to withdraw the current vector being defined and start to define it again. Before final acceptance, you may drag endings of the vectors defined previously to correct them; use the OTM Delete option to delete the previously defined vector. The latter option is accessible only if you call OTM using right click while the cursor is over some vector. You may define any number of correction vectors. Choose another function using appropriate buttons in the Calibration toolbar if necessary.

The Add net-based vectors button is used to define correction vectors one by one but with reference to pre-defined set of target points. In the situation when a raster image needs to be calibrated to match e.g. map coordinates grid, the functions automates the most standard activities. The CALIBRATOR procedure performs auto zooming to next grid point, and provides precise definition of target points without typing their coordinates.

If you enter the Add net-based vectors action with no net defined, the procedure starts from the Define net action and then continues with defining net-based vectors.

The net points defined using the Define net button are used as Target points (ends) of correction vectors - the user needs only to select the corresponding Raster points of correction vectors. Moreover, SuperEdit performs automatic zooms around the points in question, and switches automatically to successive pre-defined net points, which maximizes the operator's speed. The system zooms around the first point of the base net and you are asked to provide the corresponding raster point of the correction vector.

The OTM Next option allows you to skip defining start of the correction vector ending at the current net node. You may want to skip subsequent correction vector if a quality of the raster lying beside the nominal point is not good enough, or if the nominal point is outside the raster.

The OTM Previous option moves you back to definition of previous point, if you want to correct it.

With the OTM Next / Previous Node option, you may switch to next or previous node independently if the calibrating vector has been defined there or not.

With the OTM Next Empty / Previous Empty Node option, you may switch to next or previous node where the calibrating vector has not been defined yet.

If some of these options are disabled, it means that there are no nodes of given type in chosen direction.

With the OTM Delete Current option, you may delete the calibration vector from current node if it has been defined by mistake. This option is disabled if there is no vector at current node.

After skipping some vectors by the OTM Next option, you may decide that in fact you want to define them. For that purpose, switch the OTM Skip defined option on and press the Add net-based vectors button again. SuperEdit takes you to the first nominal point you have skipped and then to any other that has undefined correction vector. Alternatively, you may want to correct once more, redefine or simply examine all correction vectors entered so far. For that purpose, switch the OTM Skip defined option off and press the Add net-based vectors button again. Now you can correct raster points where defined or define them from the beginning where skipped. Use the OTM Reject option while correcting existing vectors if you do not want to change it. The OTM Skip defined option is accessible in Calibration Options dialog as a check box.

The OTM Finish option allows you to stop defining the correction vectors using the calibration net base. The alternative way to break this process is to activate the Add free vectors button. Do not press the Esc key on the keyboard to do it; it cancels the whole Calibrate raster command, similarly as the OTM Cancel option does. However, if you did not save the changes made to correction vectors, the system asks you to confirm it and gives you a chance to break exiting action if you pressed the Esc key by mistake.

The Add entities-based vectors button is used to define correction vectors one by one but with reference to subsequent vertices of selected vector objects. This case is convenient when you can supply (or create) a nominal vector drawing associated with the raster drawing, where actual shapes and positions of objects in raster drawing are defined by vertices of vector entities.

If you start the Calibration command with some vector entities already selected, they will be used as reference entities if applicable. If you enter the Add entities-based vectors action with no entities selected, or if the selection does not contain entities with vertices, the procedure starts from the Select entities action and then continues with defining entities-based vectors.

The vertices of vector entities chosen using the Select entities button are used as Target points (ends) of correction vectors - the user needs only to select the corresponding Raster points of correction vectors. Moreover, SuperEdit performs automatic zooms around the points in question, and switches automatically to successive nominal vertices, which maximizes the operator's speed. The system zooms around the first vertex of the first entity and you are asked to provide the corresponding raster point of the correction vector.

The details and options of Add entities-based vectors action are analogous to that of Add net-based vectors action.

Five Calibration model buttons allows you to declare the model to be used in the calibration process: Helmert model, Affine model, Bilinear model, Biquadratic model, Bicubic model with properties described at the beginning of this section. If you choose too high model order to be used with current number of correction vectors, the Toggle preview and Execute buttons become disabled. The type of Calibration model is remembered during SuperEdit session, so you do not have to change them until necessary.

The Toggle vector list button allows you to show/hide the numerical details of the calibration model.

The vectors can be previewed in the Raster Calibration Results dialog. The list box lists all Raster points and Target points as well as individual errors between Calculated points and Target points. The error values let you determine which correction vector is to be examined if its error is much worse than others are. The list can be sorted by any chosen column, to easily find e.g. the greatest error. Current Number of vectors, as well as Mean square correction and Mean square error are displayed below the list; these values assist you in choosing appropriate Calibration model. If you click a vector in the list, SuperEdit zooms automatically to show the vector at the current AutoZoom level. The AutoZoom level may be changed using the Calibration Options dialog. You may delete chosen vector by highlighting it on the list and hitting the Del key on the keyboard.

Release the Toggle vector list button if you want to close the Raster Calibration Results dialog.

The Toggle preview button allows you to switch the graphical preview of the calibration effects.

Before calibration is performed, the user may preview its mathematical model to see whether it satisfies the requested corrections. The preview displays requested Correction vectors in red and Model vectors in yellow. The calibration area is covered by a cyan reference net that is transformed according to calibration model into a blue calculated net. For Helmert, Affine and Bilinear models, the net is reduced to the four-corner frame. For Biquadratic and Bicubic models, density and shape of the calculated net shows how the calibration process will modify the raster image.

The colors of preview elements may be changed using the Calibration options dialog.

If the preview is on, any changes made to calibration model or correction vectors are immediately recalculated and shown by SuperEdit. Release the Toggle preview button if you want to remove the preview elements from Drawing window.

After evaluating the transformation's coefficients and previewing it visually, you may apply the calibration using the Execute button. After successful execution, you will be asked if you want to save calibration report (you may save it later using the Save report button).

Since performing proper calibration is often a trial-and-error process, its execution is separated from accepting the whole Calibrate raster command. After execution, you may want to examine individual correction vectors, still displayed on the screen, to see how chosen calibration model fulfills required corrections. With the Toggle preview button active, you may assure that raster data are transformed exactly along calculated vectors. If the correction vectors have been defined as net-based ones, you may automate examining process using the Add net-based vectors button with the Skip defined vectors option switched off. Use the Undo / Redo buttons on the Main toolbar to compare raster data before and after calibration is made. The Undo / Redo actions during calibration process are limited only to changes made to raster data, and not to the correction vectors, and their range cannot reach changes made before the Calibrate raster command start.

It has no sense to use repeatedly the Execute button for the same calibration data; it will rather distort raster data. It is unadvised to perform new calibration e.g. with model of higher order, defined by new correction vectors defined from the beginning on raster data once calibrated using model with lower order, because each calibration slightly deteriorates raster details.

If you are not satisfied with current calibration results, push the Undo button on the Main toolbar. Now you may complete calibration data by adding or adjusting correction vectors, and/or choosing another calibration model if appropriate; finally push the Execute button to perform new calibration from the beginning.

The Define net button starts defining the calibration net that makes it easier to enter larger series of correction vectors. When you calibrate an image, you often have a grid of points that should be placed in a regular way. In most cases, there are crossing points of the coordinate system on a map; they form a rectangular mesh. The command launches the Calibration Net dialog where you may enter numbers of horizontal and vertical net vertices, single cell width and height and the net insertion point.

Use the Pick button on the Calibration Net dialog to move the net by dragging its left lower corner and define the Net insertion point in Drawing window. Use the Create button to finally define the net.

The net vertices supply Target points’ coordinates to be used by the Add net-based vectors command.

The Select entities button starts defining the selection set that makes it easier to enter larger series of correction vectors. This case is convenient when you can supply (or create) a nominal vector drawing associated with the raster drawing, where actual shapes and positions of objects in raster drawing are defined by vertices of vector entities.

After activating the Select entities button, you may perform additional selection / deselection by clicking desired vector entities, selecting by window / crossing or using the OTM Select sub-menu options. Confirm final selection using the OTM Accept option. With empty selection, or if the selection does not contain entities with vertices, the Add entities-based vectors action cannot start properly. You may select segments, rectangles, polylines and polygons or complexes that contain such entities; other entities, like circles, texts or icons, even when selected, will not be taken into account.

The subsequent vertices of vector entities that the selection set is consisted of supply Target points’ coordinates to be used by the Add entities-based vectors command.

The Calibrate raster command supports a multi-point calibration of a whole raster image or any rectangular part of its area. After the Calibrate raster command starts, the calibration area, shown by cyan rectangle, is taken from the raster image extents; the Calibrate extents button is pushed and becomes disabled. You may change the calibration area simply by dragging its corners and defining other area. Then the Calibrate extents button is automatically released and becomes enabled. You may push it to reset the calibration area back to the raster image extents. Alternatively, you may use the OTM Delete option to delete the redefined frame, when the cursor is over edge of the rectangle; the frame defining calibration area will be restored automatically to the raster image extents.

The Set options button brings up the Calibration options dialog.

With help of thisdialog you may set colors for calibration preview elements and define default Auto Zoom level for vectors preview and editing operations. The Auto Zoom scale may be set to Current, which means that the currently used zoom level will be kept constant. Otherwise, you may define it as M:N, which means M screen pixels to N raster image pixels, or as None, which turns off the Auto Zoom feature. This method of scale declaration gives you the best displaying precision with fixed accuracy while working with raster data.

Additional Skip defined vectors check box gives you opportunity to set or clear this option before the Add net-based vectors action starts.

The Accept button lets you finally finish the Calibrate raster command, accepting its results. Using the OTM Accept option does the same.

The Accept button is available only after executing calibration that effectively changed raster data. Otherwise, use the Cancel button if you want to quit the Calibrate raster command.

If you did not save the changes made to correction vectors, the system asks you to confirm it and gives you a chance to break exiting action if you changed your mind.

The Cancel button lets you finally finish the Calibrate raster command, canceling changes made to raster data if they have been done. Using the OTM Cancel option or hitting the Esc key on the keyboard do the same.

If you did not save the changes made to correction vectors, the system asks you to confirm it and gives you a chance to break exiting action if you changed your mind or pressed the Esc key by mistake.

To define a point, click the Point button on the Vector toolbar, move the drawing cursor to desired position of the point and click the left mouse button. Points with no size are displayed as small circles with 8 pixels diameter, independently of the view scale. If you set the point size from the Thickness box on the Tools page of the Point properties dialog to some non-zero value, it will be used as absolute value of point diameter. You may also use Fill brush and Fill color combo boxes if you want the point to be filled.

The Draw Text procedure consists of two phases. In the first phase, you define a content and some parameters of a text, in the second - its position and extents. Click the Text button in the Vector toolbar to enter the first phase. The Properties dialog is displayed with the Text tab active. You can enter the content of the text (multi-line texts are allowed) and choose a text style. You can change the values as needed. Choose the OK button in the Properties dialog to go on to the second phase.

The shape of the drawing cursor changes. It becomes the same as the picture on the face of the toolbar button just clicked. If the Height parameter in the Settings tab has a positive value, the border of the text is displayed under the cursor (the size of it is calculated according to the Height parameter value). You can drag the whole text by the point defined by its insertion point. Click the left mouse button to define a position of the text. If the Height parameter in the Settings tab has a negative value (it means it is not defined), you have to point by the cursor the position where the defined text is to be placed. Click the left mouse button to define a final position of the text. The other point of the text is defined by the current cursor position and it is dragged according to the mouse movements but still its placement depends on text alignment flags (see the Settings tab in the Text Properties dialog). The next left click enters that point and the text extents are defined.

The new text is in the selected state so you can still adjust its size and position by dragging the appropriate grips. You can also invoke the Properties dialog that lets you change all the text parameters including tools used to draw it.

The Text tab is the first tab of the Properties dialog invoked for a selected text entity. It contains a multi-line edit box for content of the text and coordinates of its insertion point. The other boxes are not used in the current release.

The Style tab is the second tab of the Properties dialog invoked for a selected text entity. It contains a combo box with text styles. The list of accessible styles is established in the Style tab of the Drawing Properties dialog. Edit boxes with x and y coordinates for the insertion point of the text, text Height (units used for all those values are set in the General tab of the Drawing Properties dialog), Angle and Ratio are displayed below. There are combo boxes used to choose text Border and horizontal and vertical Alignments. The style chosen from the style list defines initial values of parameters in the Style tab. You can change all settings as needed.

The insertion point of a text is a point with coordinates defined by the text alignment flags: x coordinate by horizontal and y coordinate by the vertical flag. This point is used for defining the position of the text and for dragging it (it is exactly the position of the first text grip). While changing text extents by dragging the second grip, a position of the insertion point remains constant.

Text height is the height of the text font. The font is selected in the Font dialog that can be invoke from the Style tab of the Drawing Properties dialog.

Text ratio is the ratio that multiplied by the width of a chosen font gives the effective font width used to draw the text. It is applies to True Type fonts only.

To draw a polyline, click the Polyline button in the Vector toolbar. The shape of the drawing cursor changes. It becomes the same as the picture on the face of the button just clicked. To enter the first point, move the cursor to the desired position and click the left mouse button. Every next polyline point is defined by the current cursor position. The point and an appropriate edge are dragged according to the mouse movements. The next left click enters that point (and the edge). To end the points sequence, click the right mouse button. To end polyline with the last entered point choose the End polyline option in the pop-up menu. Choose the Step back option to adjust position of the last entered point and then proceed with the next point.

It consists of the pathname of an icon file and x and y coordinates of the icon’s center (units used are set in the General tab of the Drawing Properties dialog). You can use the Browse button to invoke the standard Windows Open dialog. The Parameters button enters the Raster Image Properties dialog with parameters used for reading and displaying the data of the icon’s raster file.

Insert entities may come from two sources: they can be references to blocks defined by user or they can be imported from DXF drawings (in the last case they are converted appropriately to internal vector data base structures). Insert entities display list of entities maintained by block definition they refer to, with individual transformation defined by insertion point, x and y scales, and rotation angle. Insert entities may be selected by clicking into any of entities displayed through them. Selection by window and by crossing works as well as for simple entities. You may drag the insert entities pointing its insertion point mark and dragging the whole insert entity to new position. You may apply the Move / Scale / Rotate transformation to insert entities and use them as components for complex entities in the same way as for other entities.

The Insert tab is the first tab of the Properties dialog invoked for a selected insert entity. It contains a combo box with current block referred by the insert entity and list of all block names contained in the drawing, from you may choose another connection. The x and y coordinates of the insertion point, the x and y scales and the rotation angle are displayed in separate edit boxes and may be changed as needed.

There are some predefined complex entities, like polygon / circle spots and annotations defined below. The user may also define his own complex entities using the DWM Complex – Create function.

The first tab named Components on the Complex Properties dialog lets you choose the appropriate entity from the list or from the preview window. Select the entity clicking its name on the list or clicking the entity itself, displayed in preview window. You may switch displaying mode in the preview window, from full view to single component view, by right clicking into its area. Click Properties... button or double-click entity’s name on the list or the selected entity in preview window, to examine properties for individual sub-entity. In case of nested complexes, several levels of Properties dialogs may follow.

By the Tools and Style tabs on the Complex Properties dialog you can examine, define and edit properties that become the common for all components of a complex. Initially, only the tools and style parameters with the same values for all entities are shown. All values that you define or change are applied to all sub-entities.

On the Measurement tab, you may examine the algebraic sum of length and areas of components of the complex, according to signs declared for each individual component.

Polygon spot is complex entity consisting of polygon and a text that can be used as a description connected with the polygon. The text size is automatically pre-set to fit whole text inside the polygon nearby its center. The text alignment flags and the border type are predefined but can be changed. In the Components tab of the Polygon Spot Properties dialog, you have an access to the properties of the polygon and the text entities separately.

The Draw Polygon Spot procedure consists of two phases. In the first phase, you define a polygon, in the second - you define a text, which can be used as a description connected with the polygon. Click the Polygon Spot button in the Vector toolbar. The shape of the drawing cursor changes. It becomes the same as the cursor used within Draw Polygon operation. Define a polygon in the way that is described in the Draw Polygon paragraph. Then the Properties dialog is displayed with the Text tab active. Define a text content in the way that is described in the Draw Text paragraph. The text is automatically placed inside the polygon nearby its center.

The new polygon spot is in the selected state so you can still adjust positions of the polygon vertices, add new ones, delete some of them or/and adjust the text position and extents by dragging the appropriate grips. You can also invoke the Properties dialog for both the polygon and text that lets you change all the parameters including tools used to draw the elements.

Circle spot is complex entity consisting of circle and a text that can be used as a description connected with the circle. The text size is automatically pre-set to fit whole text inside the circle nearby its center. The text alignment flags and the border type are predefined but can be changed. In the Components tab of the Circle Spot Properties dialog, you have an access to the properties of the circle and the text entities separately.

The Draw Circle Spot procedure consists of two phases. In the first phase, you define a circle, in the second - you define a text, which can be used as a description connected with the circle. Click the Circle Spot button in the Vector toolbar. The shape of the drawing cursor changes. It becomes the same as the cursor used within the Draw Circle operation. Define a circle in the way that is described in the Draw Circle paragraph. Then the Properties dialog is displayed with the Text tab active. Define a text content in the way that is described in Draw Text paragraph. The text is automatically placed inside the circle nearby its center.

The new circle spot is in the selected state so you can still adjust the circle position and size and the text position and extents by dragging the appropriate grips. You can also invoke the Properties dialog for both the circle and text that lets you change all the parameters including tools used to draw the elements.

An annotation is a complex entity consisting of a text and an arrow. There is no specific properties dialog for annotations but you have access to the properties of the text and the arrow entities separately. The text tab in the text properties dialog is the same as in ordinary text entity. The arrow entity is used with an annotation context only so the Arrow tab is described here as the separate subparagraph.

Arrow Tab

The Arrow tab is the first tab of the Properties dialog invoked for a selected Annotation entity and with the arrow entity chosen. It consists of x and y coordinates for both first and last end of the arrow and the length the arrow’s spike called Size. Units used are set in the General tab of the Drawing Properties dialog. You can change coordinates of the last arrow end (the first end is placed automatically in the center of the text border) and the size as needed.

Trace raster command is a specialized tool for semiautomatic tracing of raster lines. The command allows converting raster lines to vector polylines built of segments that are automatically fitted to raster lines curvature.

After the command is started you have to click a point on raster line you want to trace. The SuperEdit tracer analyses raster background and returns a polyline section that matches the pointed raster line. The line stops at breaks and intersections, so if you want to continue tracing you must click the continuation of the raster line. SuperEdit finds the next section and connects its start point to the end point of the previous one. At the end you get a single polyline covering the whole road you passed.

You may define several separate traces, thus vectorizing all necessary shapes in the raster drawing. Finished traces are drawn in color defined as current one in vector drawing (default: black). The starting part of the trace just being defined is drawn in red, while the current section just vectorized is blue, with red square grips placed in its vertices. Each time you may drag vertices of the last polyline section to correct them. Use the OTM Add Vertex / Delete Vertex options pointing where appropriate to add or delete vertices. Use the OTM Delete option to discard the whole section. The latter options are accessible only if you call OTM using right click while the cursor is over some polyline’s vertex or its edge, appropriately. To delete the section, you may use the OTM Last Section – Discard option as well.

After tracing, each section has a direction, a property that is designed to help you while following raster image lines. SuperEdit assumes that the start point of the section is an end-point closer to the last user click. You may change the section direction assumed by SuperEdit using the OTM Last Section - Flip option.

Several options modify the behavior of this basic function. They may be accessed through OTM optionsactivated by right click.

Use the OTM Cancel option, if you want to discard whole operation and delete all traces defined. If OTM Repeat option is set and you use the OTM Cancel option or Escape key, additional message asks you if you really want to discard the whole operation.

Window / Crossing – it starts the selection process defined by a dragged rectangle. Define the first corner of a rectangular area of selection with left mouse click, and drag the mouse cursor while holding the left mouse button pressed. If you drag the rectangle starting from left to right, it is drawn with blue solid line and means selection by window, i.e. all objects that lie entirely inside the rectangle are taken into account. If you drag the rectangle starting from right to left, it is drawn with blue dashed line and means selection by crossing, i.e. all objects that lie inside the rectangle or are crossed by it are taken into account. You can observe the cursor shape that changes to the small rectangle with arrow pointing the current direction. Release the left mouse button when the opposite corner is defined as needed. Relevant objects will create a new selection; this is emphasized by the small “=” sign near the selecting arrow. If you want to add pointed objects to the current selection, press Ctrl+Shift keys before releasing the left mouse button. You can observe the small “+” sign near the selecting arrow. If you want to remove pointed objects from current selection, press Ctrl+Alt keys before releasing the left mouse button. You can observe the small “-” sign near the selecting arrow. Effective selection mode and operation is described in the status line. If you want to quit the Select Window / Crossing action, press the Esc key on the keyboard or drag the cursor back to its starting position until it changes its shape back to the special cross. You may use the shortcut for entering the Select Window / Crossing action by pressing the Ctrl key on the keyboard and then pressing the left mouse button and dragging the cursor while holding the left button down. You can observe changes of the cursor shape and hints in status line displayed appropriately. This shortcut is accessible only in the normal state of SuperEdit Drawing window. You can still use short left clicks for normal pointing actions.

Current layer option selects all entities on the current layer.

All option selects all entities on all active and visible layers.

Cut – use this option to cut all entities from the selection to the Clipboard. Selected entities are copied together with layers, styles and patterns they refer.

Copy - use this option to copy all entities from the selection to the Clipboard together with layers, styles and patterns these entities refer to.

Copy To…- use this option to copy all entities from the selection to the file chosen in the Copy To... dialog, together with layers, styles and patterns these entities refer to, in a form of complete TVD drawing.

Copy All To... - use this option to save all entities together with layers, styles and patterns these entities refer to, in an external TVD vector drawing; the Copy To... dialog lets you choose a pathname for a target drawing.

Paste - use this option to paste all entities together with layers, styles and patterns these entities refer to, from the Clipboard to the foreground vector drawing (the option is enabled if Cut or Copy actions have been previously performed).

Paste From... - use this option to paste all entities together with layers, styles and patterns these entities refer to, from a TVD vector drawing; the Paste From... dialog lets you choose a pathname of a source drawing.

Import - use this option to import all vector entities supported by SuperEdit together with layers and text styles from DXF drawing format file, to the foreground vector drawing; the Open dialog lets you choose a pathname of a source drawing.

SuperEdit can include (by Import command) an external DXF file that is compatible with AutoCAD DXF drawing database version number R10 - R14 (both included). In the case of re-import of a file that was previously exported by SuperEdit all it's structure and tools are recreated so it looks and behaves like the original TVD vector drawing. In other cases some tools such as: vector hatches other then SOLID, LINE, ANSI31, ANSI37, NET and values of variable thickness' of polylines are lost. You can import DXF file with all coordinates and distances treated as they are expressed in predefined kind of units. The units can be choosen from Default units for DXF file combo-box in the Options - Configuration - Edit dialog.

Export - use this option to export all selected vector entities together with layers and text styles to DXF drawing format file. The Save As dialog that is displayed lets you choose a name and destination directory of the file. The Form of the Export DXF File dialog that is displayed after lets you choose binary or ASCII form of the exported file.

The format of exported DXF drawing file is compatible with AutoCAD DXF drawing database version number R13 and R14. The structure of the DXF drawing is conformed with SuperEdit TVD vector drawing structure as far as layers, blocks and tools are concerned. You can notice some minor divergences that result from different attitude to base notions; for instance: AutoCAD line entity can not be thick but SuperEdit segment can, SuperEdit complexes are realized as AutoCAD blocks, bitmap TVD hatches are not supported, but vector hatches are, borders of texts are not supported either.

You can export DXF file with all coordinates and distances recalculated to predefined kind of units. The units can be choosen from Default units for DXF file combo-box in the Options - Configuration - Edit dialog.

Export All - use this option to export all vector entities from the foreground vector drawing together with layers and text styles to DXF drawing format file. The Save As dialog that is displayed lets you choose a name and destination directory of the file. The Form of the Export DXF File dialog that is displayed after lets you choose binary or ASCII form of the exported file. See previous paragraph for details of exported DXF drawing format.

Gives a user possibility of importing points from text file to the current vector drawing. All but comment line of a file describes a single point. The description consists of x and y coordinates, together with (optionally) a name of point entity and a name of layer the point is to be placed. You can define the way a content of a text file is to be interpreted using dialog that may be activated from Open page of Configuration dialog.

During export the following objects generate points: Point, Segment, Rectangle, Polyline, Polygon. Only points of selected objects are exported.

Delete - use this option to delete all selected entities.

Move – use this option to move a selection to a new location. This location is defined by position of the base point of the selection. Immediately after entering this option, the new location of the selection is defined by the cursor's position. The selection is still displayed in its original position with the base point marked as small yellow circle with two perpendicular axes. A copy of the selection is dragged by its base point marked as small red circle according to movements of the cursor that takes shape of the moving symbol. Drag the copy of the selection by moving its base point to a desired position, and click the left mouse button.

To change the base point position use the OTM Base Point option and define a new base point position by the left mouse click or with Input bar and keyboard.

Use the OTM Cancel option to discard the action.

Scale - use this option to scale a selection according to a ratio of a reference vector and a scaling vector. The base point of the selection is marked as a small yellow circle with two perpendicular axes. It defines the first point of both vectors. The reference vector default position is displayed as thick yellow arrow. The scaling vector is displayed as thick red arrow, with its end connected to the cursor, which takes shape of scaling symbol. Drag the copy of the selection moving the end of scaling vector to desired size, and click the left mouse button.

To change the reference vector position use the OTM Reference vector option and define a new position of reference vector by the left mouse click or with Input bar and keyboard.

To change the base point position use the OTM Base Point option and define a new base point position by the left mouse click or with Input bar and keyboard.

Use the OTM Cancel option to discard the action.

Rotate - use this option to rotate a selection by an angle between the horizontal reference vector and a rotating vector. The base point of the selection marked as small yellow circle with two perpendicular axes, defines the first point of both vectors. The reference vector is displayed as thick yellow arrow. The rotating vector is displayed as thick red arrow, with its end connected to the cursor, which takes shape of rotating symbol. Drag the copy of the selection moving the end of rotating vector to desired angle, and click the left mouse button.

To change the reference vector position use the OTM Reference vector option and define a new position of reference vector by the left mouse click or with Input bar and keyboard.

To change the base point position use the OTM Base Point option and define a new base point position by the left mouse click or with Input bar and keyboard.

Use the OTM Cancel option to discard the action.

Create – use this option to create a new complex entity from the currently selected entities. New complex entity keeps together all child entities taken from the main drawing list. New complex entity has its own internal vector data base identifier; the individual name and external links may be assigned to it.

Explode – use this option to explode all complexes found in the selection back to the main drawing list, removing the parent complex objects.

To define (create) a block definition, draw appropriate entities, select them and choose the DWM Block - Create option. Write the name for new block in the Name box on the Blocks page and click the Add new button. Alternatively, choose an existent block from the list and click the Change button, if you want to redefine it. Click the OK button to close the dialog. Now show the position of the insertion point of the block, marked with small yellow circle. It will be used during inserting block references. Choose the OTM Accept option to create the block. The selection used to define the block list will be left untouched, removed from the drawing or replaced by insert reference according to setting of the OTM Leave / Remove / Replace selection option.

To redefine existing block e.g. by correcting some of its entities, insert its reference in 0,0 insertion point, with 1,1 scale and at 0 angle, exploding it at once. Make necessary editing changes, set final selection and choose the OTM Block - Create option choosing the same block name to change. After entering again 0,0 insertion point, choose the OTM Accept option with the OTM Remove selection option activated.

To insert the block reference into the drawing choose the DWM Block - Insert Create option or press the Insert button on the Vector toolbar. From the Insert properties dialog, choose the block definition to be used, set appropriate values for insertion point, scale and rotation angle while examining the appearance of the insert in the Preview window. You may check boxes for presetting desired transformation parameters, and / or check additional boxes for automatic Repeat, Explode or Complex options. Now you may define interactively moving, scaling and rotating operations that define insert transformation. Operations marked as preset ones will be skipped. Using appropriate OTM options, you may switch between various actions, set additional Auto Repeat option and Explode / Complex options, examine and change Properties again, and finally choose the OTM Accept option to accept the inserted reference. If you want to repeat the action, use the OTM Repeat option. With the OTM Auto Repeat option active, you may insert multiple references to the block in single operation; use the OTM Accept option when finished. With the OTM Explode option active, the inserted reference will be instantly exploded, duplicating all entities from block definition list into the drawing. The OTM Complex option works similarly, but exploded entities are grouped in complex.

If OTM Repeat option is set and you use the OTM Cancel option or Escape key, additional message asks you if you really want to discard the whole operation.

To explode inserted entities, duplicating all entities from block definition list into the drawing, select appropriate inserts and choose the OTM Block - Explode option. Only those inserts that have isotropic X and Y scales, can be exploded; otherwise the exploding action will be cancelled.

To invoke the Vector Drawing Properties dialog choose the Properties option in popup menu displayed after right mouse click, or use Properties option in Vector menu - both in situation where there are no entities selected. The dialog consists of tabs that are described in next paragraphs.

General tab

The General tab is the first tab of the Properties dialog invoked for a drawing. It consists of effective drawing extents defined by x, y coordinates of the lower left and upper right point of drawing extents. The drawing extents are calculated from extents of entities defined in the drawing. The only way of change them is to add new entity or delete/edit an existing one. Units used in the Drawing Properties and Properties dialogs of all entities can be chosen from the combo box Units.

Tools tab

You may use the Tools tab of a drawing's Properties for setting tools separately for lines, fills and bitmap hatches that are used to draw entities. The drawing's tools are used as default tools for new entities. You may re-define each entity tools independently, as they have precedence over those of a drawing.

For Line, you can choose Thickness, Style and Color (style is taken into consideration only when thickness equals zero). For Fill, you can choose Brush and Color. Transparent mode affects both lines and fills. If it is on, you can see through the entity drawn with these tools all entities lying beneath as well as the background documents - otherwise they are covered by this entity.

Layers tab

The Layers tab lists all drawing layers. There is a predefined layer with name 0. To examine or edit layer’s features, highlight a layer in the list. For the highlighted layer its Visibility, Activity and being Current modes as well as the number of entities, are displayed. You can change the visibility and activity mode as needed. There is always exactly one current layer, so switching this mode on for highlighted layer automatically turns it off for the layer that has been previously current.

To remove the highlighted layer use the Remove button. If the button is disabled, it means that the highlighted layer is not removable (layer 0 is an example of such a layer) or is not empty.

To change the name of a highlighted layer, type in a new name in the Name edit box. Click the Change button to change the name of the highlighted layer in the Layers list box.

To add a new layer, type in a new name in the Name edit box. Click the Add New button to add the new layer to the Layers list box. Set Visibility, Activity and Current modes of the added layer according to your requirements.

Styles tab

The Styles tab lists all text styles defined in the drawing. There are some predefined styles with commonly used fonts: ARIAL, TIMES and COURIER. To examine or edit style’s features, highlight a style in the list. For the highlighted style its Height, Angle, Ratio values as well as Border and Alignment types are displayed.

The Height value is the height of the text font. A negative height value means the height is not defined. If a text entity has to be drawn with such a style, it has to be defined with own, positive height value. It can be done explicitly in the Settings tab of the Text Properties dialog, or implicitly, by dragging the second grip of the text frame.

The Angle value is the default value to be used while defining texts with given style.

The Ratio value is the ratio that multiplied by a width of chosen font gives the effective font width used to draw a text. It applies to True Type fonts only.

The font is set using standard Font dialog that is invoked by the Font button.

There are combo boxes for choosing a Border type and horizontal or vertical Alignment type.

You can change all settings as needed.

To remove the highlighted style, use the Remove button. If the button is disabled, it means that the highlighted style is not removable (the predefined styles and styles that some text entities refer to them are examples of non-removable styles).

To change the name of a highlighted style, type in a new name in the Name edit box. Click the Change button to change the name of the highlighted style in the Text Styles list box.

To add a new style, type in a new name in the Name edit box. Click the Add New button to add the new style to the Text Styles list box. Set values for Height, Ratio and Angle, set Font details, and choose Border and Alignment type of the added style according to your requirements.

Patterns tab

The Patterns tab lists all patterns defined in the drawing. There are some predefined patterns with self-explaining names: HORIZONTAL, VERTICAL, FORWARD DIAGONAL, BACKWARD DIAGONAL, CROSS and DIAGONAL CROSS. To examine or edit a pattern’s features, highlight a pattern in the list. For the highlighted pattern its Distance, Thickness, Angle, line Style (it is taken into consideration only when thickness equals zero), Color and Crossing feature are displayed.

You can change all settings as needed.

To remove the highlighted pattern, use the Remove button. If the button is disabled, it means that the highlighted pattern is not removable (the predefined patterns and patterns that some entities refer to them are examples of non-removable patterns).

To change a name of the highlighted pattern, type in a new name in the Name edit box. Click the Change button to change the name of the pattern in the Hatch Patterns list box.

To add a new pattern type in a new name in the Name edit box. Click the Add New button to add the new pattern to the Hatch Patterns list box. Set Distance, Thickness and Angle values, choose a Color and a line Style and set Crossing feature of the added pattern according to your requirements.

Blocks tab

The Blocks tab lists all block definitions. To examine or edit a block, highlight it’s name on the list. You can see it in the preview window.

To remove the highlighted block use the Remove button. If the button is disabled, it means that there are inserts of it in a vector drawing. To enable the button you should remove all those inserts first.

To change the name of a highlighted block, type in a new name in the Name edit box. Click the Change button to change the name of the highlighted layer in the Blocks list box.

To find out how to add a new block see Vector editing commands – Block – Create paragraph.

To invoke an Entity Properties dialog choose the Properties option in popup menu displayed after right mouse click, or use Properties option in Vector menu - both in situation where there are some entities selected. In the case of a single complex entity and multiple entity selection, the first tab named Components on the Entity Properties dialog lets you choose the appropriate entity from the list or from the preview window, displayed within the tab.

The Properties dialog of the entity consists of tabs that are specific to the chosen entity (they are described in paragraphs related to given entity) and the tabs that are common to all entities. They are described in next paragraphs.

Tools tab

The layout of the Tools tab for an entity is an extension of that for the drawing. It is the same as far as Line, Fill and Transparency are concerned. These drawing tools define default values for the corresponding entity tools. A Pattern box lets you define hatch pattern parameters used by an entity. You can choose a pattern from the list of accessible patterns. The list is established in the Patterns tab of the Drawing Properties dialog. For the selected pattern the values of its Distance, Thickness, Angle, Style, Color and Crossing are displayed.

You can change all settings as needed, so that any single entity can have its own tools.

Selecting a new pattern in the list or the same once more resets values of all parameters according to original values defined for the pattern.

Controls of tools that are not available for the selected entity are disabled.

Measurement tab

For most entities (segment, circle, rectangle, polyline, polygon) only the Length can be measured. For some entities (circle, rectangle, and polygon), the Area can be measured, too. These values are listed in the Measurement tab. When the values are out of context for some entities, the appropriate boxes are empty.

For complex entities, as well as for multiple entity selection, measurements of length and areas may be defined as an algebraic sum of appropriate values taken from their component entities. To accomplish this effect, you may declare the sign for length and area individually for each entity to be taken into account during computation of complex measurements, using the Sign button. The default value is the “+” (plus) sign, displayed in the button before the value of interest; you may change it to “-“ (minus) sign pressing it once. Optionally, you may declare to skip the measurement of the entity in complex calculation pressing the sign button again – the “0” (zero) sign is displayed.

Data tab

Each entity in the vector database may have a list of various user-defined, numerical (integer or double) or string data attributes assigned to it. Each attribute has a unique string key. Numerical attributes may have assigned an action like addition, subtraction or skipping. The key is used as an index and can be supplied by the external database or defined by your own. The action defines the rule of the attribute value computation up to the top of the entities’ hierarchy. Data tab on tabbed Entity Properties dialog lets examine, define and edit attributes, their keys, types and actions.

The list of numerical data attributes of complex entity consists of the top-level user-defined attributes and those defined by its sub-entities. The identically keyed numerical attributes of sub-entities are computed up to the top of the entity hierarchy. The computation is done according to the following rules:

• Attributes on the sub-entity level that have the same key and type give a single computed attribute of that key and type;

• A value of computed attribute is automatically calculated as a sum or subtraction of sub-entities attribute values according to actions assigned to them.

Notice that Properties dialog for a multiple selection supports Data tab for that selection with the full attribute capabilities. In this way, you may easily examine the on-line computed aggregated data values for attributes of interest if they are defined for individual components.

Object tab

Each entity has its original numerical identifier, called object identifier. An entity can also have its own object name. Both are defined on Object tab. The object identifier is automatically defined and assigned when an entity is added to the drawing. Object name can by defined and edited by you. You can use it for various purposes - see stamps libraries for example.

The next group of checkboxes displays the state of active object notifications that are not supported in the current release.

The Properties... command is active only when exactly one subdocument is highlighted on the Subdocuments list. This command launches the Raster Image Properties dialog or Vector Drawing Properties dialog, depending on the current subdocument type. Using the dialog, you may inspect and set various properties and parameters of the highlighted subdocument.

The Vector Drawing Properties dialog has been described earlier.

The Raster Image Properties dialog can have two, three or four tabbed pages. The pages titled Parameters and Info is always present. The Pages tab is present only when the current raster image has multiple pages. The Colors tab is present only when at least one image page is monochrome, so that it may have a presentation color assigned.

Info tab

In the Info tab, you can inspect various raster file parameters.

Pages tab

On the Pages tab, you can select the current tab of the multi-page raster image.

Colors tab

On the Colors tab, you can select a presentation color for monochrome raster image.

The values of image parameters are saved in the image file, if the image format allows for it. An additional attribute file, with the same name as the image file name but with TAF extension, stores all parameters in ASCII format (see the section called “Appendices” for description of the TAF file format). The additional file is located in the same disk directory as the image file. The additional attribute file is necessary, because not every parameter can be saved in the original image file. Parameters saved in the original image file override those saved in its additional attribute file. The creation and reading of attribute files can be controlled using the BRAOpenOptions parameter in the supered.ini file (see the section called “SUPERED.INI file” for description of the supered.ini file).

The parameter values are read from the image file and possibly from its attribute file. All of them can be changed, except for the Effective Image Extents that are calculated from other parameters. When any parameter has been changed, the image is considered changed, and SuperEdit asks the user for saving changes in a file, when it is about to be closed.

The Enable command turns visible all subdocuments that are highlighted on the Subdocuments list. The visibility may be also affected by the drawing’s position on the Subdocuments list (see the Subdocuments order section below).

The Disable command turns invisible all subdocuments that are highlighted on the Subdocuments list.

The Select command changes to selected the state of all highlighted subdocuments on the Subdocuments list. The S character appears before the name of each selected subdocument, which is additionally displayed, in a different color. This method of selecting is alternative to the cursor pointing method described in the Select / Edit Viewports command section below.

The Unselect command clears the selected state of all highlighted subdocuments on the Subdocuments list. The S character before the name of each selected subdocument disappears and the color of its line is changed to the standard one. This method of making unselected is alternative to the cursor pointing method described in the Select / Edit Viewports command section below.

Thefollowing four commands (buttons) allow to control the order in which the subdocuments overlap one another, when the composite document is displayed or printed. Each of them moves the highlighted subdocument entries on the composite document’s Subdocuments list.

The Add... command adds a new subdocument to the current composite document. It launches a dialog box for selection of a drawing file to be added.

The Delete command removes links to currently highlighted subdocuments from the composite document. Of course, it does not delete the drawings’ files.

The Change Link... command is used to define a new path to the subdocument that is highlighted on the Subdocuments list. It is especially useful when the previous files location is not valid (indicated by N/A on the Subdocuments list), e.g. after moving it to another directory. The Change Link... command can be issued only when exactly one subdocument is highlighted on the Subdocuments list.

The Save command is active only when exactly one subdocument is highlighted on the Subdocuments list and if there are any unsaved changes made to its contents or parameters. This command saves the changes to the highlighted drawing file and/or to its associated attribute file. It operates only on the highlighted subdocument and does not save changes made to other subdocuments or to the whole composite document that should be saved using the Save command (or the Save button on the Main toolbar).

The Save As... command is active only when exactly one subdocument is highlighted on the Subdocuments list. It copies the highlighted drawing file (with its associated attributes file (TAF), if one exists) to the location specified by the user in the Save As... dialog box. The highlighted source subdocument file is left unchanged while all editing changes made to it are saved in the newly created copy. The Save As... command updates the current link from the composite document to the highlighted drawing, so that it contains the path to the newly created copy.

The Copy To... command is active only when exactly one subdocument is highlighted on the Subdocuments list. It copies the highlighted drawing file (with its associated attributes file (TAF), if one exists) to the location specified by the user in the Copy To... dialog box. The highlighted source subdocument is left unchanged while all editing changes made to it are saved in the newly created copy. The Copy To... command leaves the current composite document unchanged, i.e. linked to the original drawing file.

Use the Absolute command to display and store absolute path to subdocument file for all selected subdocuments on the Subdocuments list. The option is enabled only if all subdocument files are placed in the same directory as the composite document file, or in its subdirectories. In other case the paths displayed and stored are always absolute.

Use the Relative command to display and store relative path to subdocument file (with regard to composite document file) for all selected subdocuments on the Subdocuments list. The option is enabled only if all subdocument files are placed in the same directory as the composite document file, or in its subdirectories. In other case the paths displayed and stored are always absolute.

You may want to use relative paths for subdocuments when you want to move the composite document file with its subdocument files to another directory, drive or computer, or to use it in net environment.

The Open tab allows you to configure options that control opening SuperEdit files:

If this option is checked, SuperEdit automatically selects a single image file, or a TCD file with only one subdocument, immediately after the open operation. This option prepares the image to be ready for editing, not only viewing. This option corresponds to the AutoSelectSingleFile parameter in the [TSLRVC Library Settings] section in the supered.ini file.

The Parameters file options... button invokes External Parameters File dialog. Use it to control what kind of an attribute file (i.e. parameter file that accompanies raster file) is used.

Click a name of kind of attribute file and check the way you want to use it (read while opening, write while saving, create if not exist). Use Move Up and Move Down buttons to establish priority rules. They determine what kind of attribute file is to be read if there is more then one on a disk.

A prototype drawing is the ordinary TVD vector drawing that can be used as a pattern while creating a new vector drawing (in Document - Add New Vector command).

You can use a browse button to find the wanted file (the chosen file name and location appears in an edit box).

It is possible to choose with a check-box whether or not to use the prototype drawing in Add new vector command. The prototype is used only if the check-box is set and the prototype-path is not empty.

The Edit tab allows you to define the following options:

You may easily call most recently used command of any type, using the Repeat option from DWM menu.

Defining simple vector entities, e.g. points, segments, ..., may be performed in automatically repeatable fashion; this feature may be switched off if not needed. With command autorepeat enabled, use OTM Break option (instead of OTM Cancel) to stop defining entities.

You may use click-and-drag technique to start defining zoom window not only in idle SuperEdit state, but during most editing actions as well. This feature may be switched off if not needed.

Option defines how many undo steps are allowed for raster editing operations.

The Raster editor settings button invokes Raster editor settings dialog.

The available settings are grouped in three boxes:

Filter type Choice of filter type influences the way of calculating color of each pixel in transformed image during resizing, rotating and calibrating. The Linear and Cubic filters interpolate color value taking two or four adjacent pixels according to linear and cubic interpolation formulae, appropriately. The Lanczos, Hamming and Blackman filters take into account color values from six neighboring pixels. The default setting is Linear filter, which is the fastest one and precise enough for simple applications, like technical drawings and maps.

Use filters for files Although precise choice of filter type may be individual for each type of image, the general decision when to use filter and when to not filter at all may be taken basing on image color format. Option In any color format enables filtering always when transforming color and gray-scaled images. Option Above 16 colors enables filtering for color and gray-scaled 256-palette images as well as for true-color images. Option In true-color only limits filtering only to true-color images. Option Do not use disables filtering at all. The default setting is Above 16 colors.

Round bits number to When the palette image is to be transformed using filtering, it requires converting to true-color format for processing and converting result back while storing. Rounding 8 bits per each basic color to some lower value, e.g. 7, 6, 5 or 4 bits may shorten converting and processing time, with slight degradation of color precision. Successive options named 4 bits per color, 5 bits per color, 6 bits per color and 7 bits per color declare which rounding is to be used. The default setting is rounding to 6 bits per each basic color.

All settings chosen during editing session are stored in INI file. See http://tessel.com/for more details of the settings.

SuperEdit can display several raster and vector drawings at the same time. To place them in the common world system coordinates, the coordinates and distances related data have to be interpreted in a context of units they have been defined. Default file units support lets you set and store (in TAF files) default units for any opened drawing file that does not contain such information inside it. The units can be choosen from Default units combo-boxes in the Options - Configuration - Edit dialog. You can set units for:

a) background raster files,

b) backgroud vector files (vector drawings in DWG, DXF and HPGL format that SuperEdit with TSLETF option installed can display but not edit),

c) TCD (Tessel Composite Document) files,

d) DXF files, that can be imported/exported to/from current foreground TVD drawing).

Path name to the disk directory where SuperEdit’s temporary files will be created.

The Save tab allows you to defining the following options:

If this option is checked, SuperEdit saves not only TCD file with links to raster images or vector drawings, but also copy all subdocuments to new files. See the Save As... command description for more details. This option corresponds to the TCDSaveMode parameter in the [TSLRVC Library Settings] section in the supered.ini file.

If this option is selected, SuperEdit creates the multi-page destination file while converting multiple input files.

Some raster formats may be saved under different file extensions. These include Vidar, CALS Bitmap and TIFF. You can define preferred extension for each format.

The Magnifying Glass tab allows you to configure the Magnifying Glass tool. Checking Magnifying Glass active box activates the function. The Magnifying Glass window displays a zoomed area around the position of the mouse pointer when the Magnifying Glass is activated. Using a hot key, you can activate Magnifying Glass even in the course of a command defining process, especially when the next point is expected. If raster snap was active and successful, its result will be indicated by a cross symbol. If the snap result is not satisfactory, you may pick a new point precisely. The Keep on display option controls the method of closing the Magnifying Glass window. If option is not selected the Magnifying Glass window is closed automatically if you move the mouse cursor outside the window or you pick a new point inside the window. Otherwise, the Magnifying Glass window disappears after pressing the Esc key or right mouse click. The Esc key cancels the point in the Magnifying Glass window. The right mouse click accepts the point and passes its coordinates to SuperEdit command.

There are several methods of using the Magnifying Glass:

Magnifying Glass window will be displayed after pressing the configured hot key

Magnifying Glass window will be displayed if you tried to snap to raster and no snap point was found. This option is very useful with bad quality raster images that have jagged lines, many gaps, etc., that cause frequent raster snap failures

Magnifying Glass window will be displayed after every raster snap trial, both unsuccessful and successful, to verify and/or correct its result

Magnifying Glass window will be closed after pressing the Esc key, which cancels the point, or right mouse click, which accepts the point.

Other parameters on the Magnifying Glass tab allow the user to customize the Magnifying Glass window size in pixels and the magnification scale of raster. Current hot key may be changed simply by deleting its description from its box and pressing a new key (or combination).

The Raster Snap tab allows you to configure the Raster snap feature.

If the Snap to raster active option is checked, SuperEdit is put into continuous snap mode. Every click in the drawing window is passed to SuperEdit that searches for the best possible raster point that matches specified snap modes. You may snap to the center of circular raster shape, to intersection of raster lines, to the end of raster line, corner of raster line, to the nearest point on the centerline or to the edge of raster area. Raster Snap modes may be selected (and combined, if necessary) by checking their boxes in the dialog.

When multiple Snap modes are selected, SuperEdit attempts to detect the relevant features of raster images according to the following hierarchy that corresponds to the order of the snap mode options shown in the dialog:

If, for example, both raster line corner and intersection are detected within the snap pickbox area, the point of intersection, that is higher in the hierarchy, will be returned.

SuperEdit activates a pickbox to show the area where to look for a snap point. Depending on raster image contents and zoom level the user should chose a convenient pickbox size.

Snap modes that you choose with Snap tab set the modes for single click; snaps that are activated from the Options and tools Menu (OTM), either.

You can use the Raster Snap toolbar as the other way to choose and set preferred permanent and single click raster snaps. The state of Snap tab options is stored in supered.ini file and defines the initial state of them.

The Vector Snap tab allows you to configure the Vector snap feature.

If the Snap to vector active option is checked, SuperEdit is put into continuous snap mode. Every click in the drawing window is passed to SuperEdit that searches for the best possible raster point that matches specified snap modes. You may snap to the center of circular raster shape, to intersection of raster lines, to the end of raster line, corner of raster line, to the nearest point on the centerline or to the edge of raster area. Raster Snap modes may be selected (and combined, if necessary) by checking their boxes in the dialog.

When multiple Snap modes are selected, SuperEdit attempts to detect the relevant features of raster images according to the following hierarchy that corresponds to the order of the snap mode options shown in the dialog:

If, for example, both intersection and endpoint are detected within the vector snap pickbox area, the point of intersection, that is higher in the hierarchy, will be returned.

After activating vector snap, a blue pickbox is displayed together with drawing cursor (the pickbox concerned with raster snap is red). After successful vector snap, a small blue circle is displayed in the snapped position (after successful raster snap, the snapped position is marked as small red cross). Depending on raster image contents and zoom level the user should chose a convenient pickbox size.

Snap modes that you choose with Snap tab set the modes for single click; snaps that are activated from the Options and tools Menu (OTM), either.

You can use the Vector Snap toolbar as the other way to choose and set preferred permanent and single click vector snaps. The state of Vector Snap tab options is stored in supered.ini file and defines the initial state of them.

The View tab allows you to define view options:

If this option is checked, SuperEdit uses dithering to improve image colors mapping. The option is especially useful when displaying images with many colors on display devices with only 16 or 256 physical colors. This option corresponds to the DitherMode parameter in the [TSLRVC Library Settings] section in the supered.ini file.

During diplaying process, a new proprietary technology called ClearView has been introduced. It gives maximal readability of raster images being displayed, specially when they are presented in screen resolution lower than original image resolution, e.g. during zoom-out.

In case of monochromatic images, this technology additionally applies adaptive shaping of gray-scaling curve, thus giving optimal readability independently from image contents and viewing scale.

In case of color images, readability of image details and clarity of image colors have been greatly enhanced. In case of palette drawings, ClearView eliminates false artifacts observed so far. You may want to switch the ClearView feature off to speed-up redisplaying process.

Use the option to display crosshair that can help you defining commands and vector entities.

This option is responsible for switching on or off the usage of transparency information defined in a raster image.

The View cache options button invoke configuration dialogs of SuperEdit’s integrated view and print cache. All modified parameters are stored in the supered.ini file. More information about modified property is specified in the section called “SUPERED.INI file”.

SuperEdit supports displaying cursor which size is constant in world coordinates. Use the option to invoke World-size cursor settings dialog and define cursor size and switch it on or off. World-size cursor is not available in the Print Preview state.

It is possible now to display grid in the Drawing window. The grid size may be set independently in x and y directions, defined in user-preferred units, and the grid itself may be activated from separate dialog after pushing Grid options button from View page on the Configuration dialog. Grid nodes are displayed as dots, with major grid lines enhanced. If the grid is too dense to display, some of its nodes are omitted. You may easily switch the grid on and off using the Grid button on main toolbar, placed together with Crosshair and World-size cursor buttons.

You may activate snap to grid in drawing operations, using new Grid snap button placed on the Input bar, or hit F9 key. Similarly, you may activate orthogonal snap, using Ortho snap button placed on the Input bar, or hit F8 key. Both F8 and F9 keys are used as toggles.

The Tracer tab allows you to define the following options:

If checked, a traced polyline will have a width that matches the raster line width. If the option is not checked, the traced polyline width will be set to value declared in the Line width edit box. This option corresponds to the UseTraceWidths parameter in the [Raster Snap Options] section in the supered.ini file.

Available values are 1...32. The option says how precise to estimate raster line curvature. Smaller values give better precision. This option corresponds to the CurvePar parameter in the [Raster Snap Options] section in the supered.ini file.

Available values are 1...32. The option defines minimal segment length in pixels. Smaller values allow shorter minimal segments to be used for tracing. This option corresponds to the SegmentPar parameter in the [Raster Snap Options] section in the supered.ini file.

Defines the uniform width of traced lines. This option corresponds to the TraceWidth parameter in the [Raster Snap Options] section in the supered.ini file.

The Print tab allows you to define the following options:

If this option is checked, SuperEdit uses the original image colors while printing. If the option is not checked, the images are printed as if they were black. This option corresponds to the PrintColors parameter in the [TSLPPL Library Settings] section in the supered.ini file.

The Print cache options... button invokes configuration dialogs of SuperEdit’s integrated print cache. All modified parameters are stored in the supered.ini file. More information about modified property is specified in the section called “SUPERED.INI file”.

A printing template is the vector drawing that defines document localization on the paper sheet and may contain a standard border definition. SuperEdit package contains a separate utility called Template Editor for preparing printing template drawings. The Template Editor is described in appendix. Template Editor allows you to define a standard frame for printing documents in Portrait and Landscape orientations. If you don’t define default print template, SuperEdit fits the document to the paper sheet on the current system printer.

Use the option to select TVD drawing with a print template that is previously defined by Template Editor. The Select printing template file dialog is displayed (it is the standard Open dialog with TVD as predefined file type). The template selected is used for subsequent Print Preview and Print options.

If you want to print a document without the previously selected print template, use the Reset option. Then SuperEdit fits the document to the paper sheet on the current system printer.

Information about geographical mapping to be used while viewing raster drawing, can be stored in and retrieved from Tessel Attribute File (*.TAF file).

You may examine contents of "Options - Geographical Mapping - Load" option to check geocoding info associated with raster drawing, and activate this option to force the mapping to be active. Alternatively, you may select some mapping and choose "Options - Geographical Mapping - Save" option to associate it with the drawing.

Both options are enabled only if there is only one raster drawing opened, or (in case of composite documents containing several raster drawings) only one raster drawing selected.

The same geocoding information, together with georeferencing data, are stored and retrieved in GeoTIFF format in TIFF drawing files and in MapInfo (MIF) format in *.TAB files (if selected after activating "Options - Configuration - Open tab - Parameters file options" button).

Possibility of retrieving geocoding information stored in GeoTIFF or MapInfo format is limited to geographical mappings implemented in TSLGEO dynamic link library.
