Lilith River	a4cbf7bbaf	test: add 28 format-variant test images covering compression, tiled, BigTIFF, float, signed, CMYK, palette, RGBA, multi-page, and big-endian ... Expand gen_seq_tiff.c with writers for standard-depth formats that exercise different decoder code paths. All 55 seq-* images are 16x16, libtiff-generated, and cross-validated against tifffile. New coverage: - Compression: LZW, Deflate, PackBits (gray 8/16-bit, RGB 8-bit) - LZW + horizontal predictor (8-bit gray) - Tiled layout: gray 8/16-bit, RGB 8-bit (16x16 tiles) - BigTIFF: gray 8-bit, RGB 16-bit - Float: gray f32/f64, RGB f32 - Signed integer: i8, i16, i32 - CMYK: 8-bit, 16-bit - Palette/indexed: 4-bit, 8-bit (with known colormap) - RGBA with associated alpha: 8-bit, 16-bit - Multi-page: 3-page gray 8-bit (all pages verified) - Big-endian byte order: gray 8/16-bit, RGB 8-bit Total: 298 tests, all passing.	2026-03-10 06:02:19 -06:00
Lilith River	26c32431fa	test: regenerate seq-* test images using libtiff C API ... Replace Python-generated test TIFFs with libtiff-generated ones to eliminate circular validation. The C program (gen_seq_tiff.c) uses libtiff's TIFFWriteScanline with MSB-first packed bit streams. Cross-validated: tifffile independently confirms all 27 images match the original Python-generated versions byte-for-byte. tiffinfo validates all IFD structures. All 27 image-tiff decode tests pass unchanged.	2026-03-10 06:02:19 -06:00
