% 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).
