-% 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).
