Each drawing file can have an attribute file associated with it, where the drawing’s technical parameters are stored. It is especially useful to store the parameters that can not be stored in the drawing file itself due to its format limitations. Some image file formats allow storing more parameters than others do. The values of image parameters are saved in the image file, if the image format allows for it, and in an additional parameter file with the same name as the image file name but with TAF (Tessel Attribute File) extension. The TAF file is located in the same disk directory as the image file.

Parameters saved in the image file override parameters saved in the additional parameter file (TAF).

Creating and using of attribute files can be disabled using the BRAOpenOptions parameter in corresponding program .ini file (see ).

A TAF file is a text file formatted in sections (like INI files). If the image file is a multipage raster file, each section describes a separate page. The first page is described by the [RasterImageParams] section, the second page is described by the [RasterImageParams.1] section and so on. Parameters of a drawing file in one of vector formats (DWG or DXF) are specified in the [VectorDrawingParams] section. Thus it is possible to have two drawing files with the same file name and different file name extensions in one disk directory: one in raster format and one in vector format and to use a common TAF file for them. Their parameters are located in different sections of the same TAF file. Vector drawings use only two parameters: Units and Orientation.

Section name line syntax: [<section_name>]

Parameter line syntax: <Parameter_name>=<Parameter_value>

Parameters description:

Units - the code number of units used to define the insertion point of the image; one of the following values:

1

inch

2

foot

3

yard

4

mile

5

millimeter

6

centimeter

7

meter

8

kilometer

Color - the color number from the AutoCAD palette (for monochrome raster images only)

Orientation - the image’s orientation. Defined in raster terms (lines and columns of pixels) but maintaining analogical meaning also for vector drawings. The Orientation can have one of the following values:

1

first line at the top, first column at the left side

2

first line at the top, first column at the right side

3

first line at the bottom, first column at the right side

4

first line at the bottom, first column at the left side

5

first line at the left side, first column at the top

6

first line at the right side, first column at the top

7

first line at the right side, first column at the bottom

8

first line at the left side, first column at the bottom

See also the picture below for the reference to coresponding above numbers.

XInsertionPoint - X coordinate of the lower left corner of the image;

YInsertionPoint - Y coordinate of the lower left corner of the image;

XScale - the horizontal scale of the image;

YScale - the vertical scale of the image;

XResolution - image’s horizontal resolution;

YResolution - image’s vertical resolution;

Length - the number of pixels in a single raster line;

Width - the number of raster lines;

Comment - image’s description or a remark text.

Geographical Mapping Systemsoption are available from context menu after clicking Right Mouse button while holding left Ctrl key while using CADRaster.

While in HyperDoc it can be open from Drawing menu.

Select Geographical Mapping and then Select... to open Geographical Mapping dialog box where you can select mapping.

The Gauss-Krüger projection system is a conformal, cylindrical, transverse Mercator projection of the earth's ellipsoid surface made on the plane in such a way, that the center meridian is transformed without distortions and the symmetry against the meridian is also preserved.

Generally, the transformation of the whole surface of the earth's ellipsoid (or a large part of it) results in the high level of distortions. To make it acceptable, the ellipsoid is divided to meridional strips, each 3 or 6 degree wide. Then subsequently, the strips are projected on the cylindrical surface, which is tangent to the ellipsoid along the central meridian of each strip. To balance the error level along distance from the central meridian the scale factor is introduced. The scale factor 1.0 means that there is no error on the center meridian points and a maximal error is on the both edges of the strip. A smaller then one (1.0) scale factor balances the error for the central meridian points with the error on the strip edges.

After the projection, the central meridian of strip and the equator are perpendicular. This is the reason to base on them the local strip's coordinate system, with axes traditionally marked as X for north direction and Y for east direction. Additional offset in the X-Y coordinate system allows avoiding negative coordinates values to the left from central meridian and below the equator.

The maximal distortion in a 3-degree strip is 17 cm/km and in a 6-degree strip – 70 cm/km. It is much less then the printed map's accuracy, which is about 0.2 mm.

CADRaster recognizes and supports raster drawings stored in popular JPEG format (extensions JPG, JPEG).

Various parameters that influence compression level, precision of drawing details and processing time during saving or converting to JPEG format, may be controlled from "JPEG Format Save Options" dialog called from "Save" tab on "Configuration" dialog.

DCT method

Selects the algorithm used for the DCT step. Choices are:

SLOW: slow but accurate integer algorithm

FAST: faster, less accurate integer method (DEFAULT)

FLOAT: floating-point method

Restart

To emit restart markers in the JPEG file, set one of these nonzero. Set restart interval in blocks to specify the exact interval in MCU blocks. Set restart interval in rows to specify the interval in MCU rows. Defaults are zero (no restarts). One restart marker per MCU row is often a good choice.

Smooth

Smooth If non-zero, the input image is smoothed; the value should be 1 for minimal smoothing to 100 for maximum smoothing. The default is zero.

Quality

Baseline

Constructs JPEG quantization tables appropriate for the indicated quality setting. The quality value is expressed on the 0..100 scale recommended by IJG. If the baseline parameter is TRUE, then the quantization table entries are constrained to the range 1..255 for full JPEG baseline compatibility. In the current implementation, this only makes a difference for quality settings below 25, and it effectively prevents very small/low quality files from being generated.

To learn more about how to use JPEG, see http://www.faqs.org/faqs/jpeg-faq/.

Due to the compression nature used in raster drawings stored in JPEG format, applying some raster editing operations, like clearing areas or cutting and pasting, may result in some artifacts inside edited areas, depending on compression parameters used in original drawing.
