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 p
