Lassen Drive - Suite A-134, San Rafael, +% CA 94903, U.S.A., +1(415)492-9861, for further information. +% +% +% Tests for the image operators + +% Specifications for Image operator testing. +% +% 1. All 8 standard orientations (0, 90, 180, 270 degree rotations with +% and without reflection); ditto those orientations perturbed by +/- +% 10 degrees, and by 45 degrees. +% +% Enough space is provided around images on a test page to allow +% these permutations to use the same page layout. This will make +% test page construction easier and simplify page checking. +% +% 2. All 9 image types (ImageType 1 mask, ImageType 1 opaque, +% ImageType 3 with all 3 InterleaveTypes and with unequal scaling +% for InterleaveType 2 and 3, ImageType 4 with both range and +% single-point matching). +% +% 3. DeviceGray, DeviceRGB, and DeviceN color, both direct and Indexed. +% Indexed color will use the common pallete size of 256 colors. +% +% 4. For simple masks, both colored and uncolored Patterns. +% +% 5. CombineWithColor true and false; several different colors for the +% true case (including black, white, other solid colors, halftones, +% and patterns). +% +% 6. Source transparency true and false. +% +% 7. Texture transparency true and false. +% +% 8. Different RasterOp values. +% +% 9. For ImageType 4, different color keys (out-of-range, specific +% color other than white, range without white). +% +% 10. String, file, and procedure data sources; for multi-component +% color spaces, MultipleDataSources = true. This is tested by +% constructing string data sources that are used as input to +% SubFileDecode filter to create a filetype data source. These +% filters are read into scratch strings for the procedure data +% source case. The procedure data source scratch string length +% does not match the raster width, and the width x height is +% not an integer multiple of the string length. +% +% Also for the File case, the number of bytes consumed is +% checked after the image operator to verify that the exact +% amount of data is used. This is particularly important when +% the currentfile is used as a source (possibly through a +% filter. +% +% Image bytes per line are < 500 bytes to exercise direct and +% buffer copy gs_image_next_planes mode with the default stream +% buffer size of 512 bytes. Procedure string size is greater +% than the image bytes per line for the same reason (sM and sD). +% +% Total string size is kept below 65535. + +/WidthRGB 83 def +/HeightRGB 89 def + +% +% 11. Banded and non-banded rendering. This can be tested by running +% test files throuch with different page device parameters to +% force banding vs. page mode. +% +% ------------------------------------------------------------------------- +% +% Testing the RasterOp-related functions (5/6/7/8) is not necessary at this +% time. They are well isolated logically. +% +% Testing orientation (1) and color masking (9) would be a good idea at some +% point, because this code has broken many times in the past and has had a +% long bug tail. +% +% The really important things to test are 2 (image type), 3/4 (color space -- +% but only with regard to number of components, plus DeviceN and simple masks +% with a Pattern, which exercise special control paths), 10 (data source), +% and 11 (banding modes). +% +% ========================================================================== + +% +% Procedure to generate test mask data +% +% WM and HM must be defined prior to invocation +% MaskGen - +% +% The mask data is stored into a string named /MaskData +% +% The mask consists of a "target".
