Description

This pull request strengthens the handling of CCITT (fax) TIFF decompression by adding strict validation to prevent writing more pixels than the image width, especially in tiled images. It also introduces targeted regression tests to ensure these checks work as intended. The changes improve both the robustness and reliability of TIFF decoding.

TIFF CCITT Decompression Robustness:

• Added checks in ModifiedHuffmanTiffCompression, T4TiffCompression, and T6TiffCompression to throw an ImageFormatException if a decoded run exceeds the image row width, preventing buffer overruns and ensuring data integrity. [1] [2] [3] [4] [5]
• Updated error messages for consistency and clarity in T4BitReader methods. [1] [2]

Tiled TIFF Support Improvements:

• Modified the TIFF decompressor factory and decoder to correctly handle tiled images by passing the tile width to fax decompressors, ensuring proper row width validation during decompression. [1] [2] [3]

Testing and Regression Coverage:

• Added new regression tests in CcittTiffCompressionTests.cs to verify that oversized runs in both strip-based and tiled CCITT TIFF images throw the correct ImageFormatException. These tests use compressed TIFF samples to keep the test codebase small and efficient.
