Addresses #26560.
Currently, the test suite only has a single test case (
bitmap-symbol-context-reuse) for testing arithmetic context reuse in symbol dictionaries where refinement (uses_refinement_or_aggregate_coding) and Huffman coding (uses_huffman_encoding) are both set to false.This PR adds two new test cases under
Tests/LibGfx/test-inputs/jbig2to ensure context reuse is fully covered when refinement is enabled:refagg=1andhuffman=0(bitmap-symbol-context-reuse-refagg)refagg=1andhuffman=1(bitmap-symbol-context-reuse-huffman-refagg)Both test inputs have been successfully compiled to
.jbig2usingjbig2-from-json, registered in theTestImageDecodertest suite and verified to decode and match the reference bitmap pixel-by-pixel.
