James Jackson-South	b142dbacff	Add AOT compiler seeds for ICO, CUR, QOI formats - Add ICO, CUR, and QOI encoder/decoder seeding in AotCompilerTools - Introduce SeedPixelOperations() to explicitly seed all built-in pixel format PixelOperations<T> specializations for Mono WASM AOT - Add [DynamicDependency] on Configuration constructors to keep the seed graph visible to .NET trimmers - Add AI coding guideline files (AGENTS.md, CLAUDE.md, GEMINI.md, copilot-instructions.md) - Update .gitattributes to treat .a, .dylib, and .so as binary	1 month ago
James Jackson-South	e2b43407cc	Handle ulong values for EXIF Long writes Fixes EXIF serialization when `ExifLong8Array` downgrades to `ExifDataType.Long` but still stores values as `ulong`. `ExifWriter.WriteValue` now handles `ulong` inputs in the `Long` branch by writing 32-bit values, and a BigTIFF metadata test verifies mixed in-range values are written correctly as two little-endian `uint`s.	1 month ago
James Jackson-South	494d2dd97b	Clone TIFF profiles into image metadata Update TIFF metadata creation to build ImageMetadata after IFD tag processing and copy root-frame EXIF/ICC/IPTC/XMP profiles to image scope via deep clones. This keeps image-level metadata in sync for downstream single-frame encoders while preserving independent mutability between frame and image metadata. Tests now cover preserved ICC handling and verify image-level profile presence, equality, and non-shared instances for EXIF/XMP/IPTC, including ignore-metadata behavior.	1 month ago
James Jackson-South	dfdc0734e3	Validate CgBI chunk order in PNG decoder Handle CgBI chunks consistently when they appear after IHDR by routing both identify/decode paths through a new `ReadCgbiChunk()` method that immediately validates already-read headers. This prevents invalid CgBI images from bypassing compatibility checks when chunk order is unusual. Added PNG tests that reorder the first two chunks to confirm incompatible CgBI headers now throw in both identify and decode flows. Also renames `ZlibInflateStream` to `ZlibInflateReader` and updates EXR/PNG/TIFF call sites for clearer intent.	1 month ago
James Jackson-South	3d89f941d4	Fix degeneracy check for resize transforms Use exact zero determinant checks in `TransformUtilities.IsDegenerate` for `Matrix3x2` and `Matrix4x4` instead of epsilon-based near-zero detection, preventing valid transforms from being treated as degenerate during extreme downscales. Added a regression test for issue #3156 to verify resizing large square images (1024/2048) to 1x1 succeeds and preserves the expected pixel.	1 month ago

James Jackson-South	e1c3013f96	Fix bulk RGBA-compatible conversion bounds Slice the destination span to source length in `Vector4Converters.RgbaCompatible.FromVector4` so SIMD/scalar tails never process spare destination capacity. Expanded pixel-format tests to run across hardware intrinsic configurations, added dedicated RGB24/BGR24 bulk conversion coverage with sentinel checks for out-of-range writes, and relaxed associated-alpha half packing assertions to treat NaN payload differences as valid IEEE behavior.	2 months ago

James Jackson-South	2ffa9fb07b	Add binary16 pixel formats and scaling fixes Introduces `RgbaHalf` and `RgbaHalfP` plus bulk pixel-operation support, updates AOT seeding, and routes EXR decoding through the new scaled conversions. Also fixes scaled/native range handling for half, SNORM, and signed integer pixel formats, and expands tests for the new layouts and edge cases.	2 months ago
