James Jackson-South	8ca712019e	Fix 16-bit binary PBM sample byte order The binary PGM and PPM formats store 16-bit samples most significant byte first. The decoder and encoder read and wrote them in native little-endian order, so every wide sample was byte swapped. This corrects the swizzled colors reported for 16-bit PPM images. - Reverse the sample byte order in BinaryDecoder and BinaryEncoder. - Fix integer division in the max pixel value upscale factor. - Add exact-value, reference-decoder, upscale, and round-trip tests. - Add a 16-bit PPM test image and its Magick-anchored reference PNG. - Document the binary decoder and encoder in full.	4 weeks ago
James Jackson-South	3d3f49fab8	Refine alpha conversion and AOT seeding Introduce explicit associated/unassociated pixel conversion APIs across `IPixel` and `PixelOperations`, and rework associated-alpha operations to use representation-aware bulk hooks. Update pixel implementations, converters, blenders, and generated code to consistently apply `Premultiply`/`UnPremultiply` semantics, plus SIMD-backed conversion paths for half and signed formats. Fix codec and processing behavior where alpha handling was incorrect or lossy (notably TIFF/EXR decode/encode, convolution/resize/filter/normalization/dithering paths), and add targeted tests for these cases. Expand AOT compiler roots (including EXR and additional pixel/processor coverage), add a new public API test project for pixel-operations extensibility, and add broad alpha-representation and quantization regression coverage.	2 months ago
James Jackson-South	4b07920c7c	Fix alpha association and SIMD rounding parity Refactors `Color` to track both exposed and stored alpha representations, adds `ToScaledVector4(PixelAlphaRepresentation)`, and adjusts pixel conversion paths so associated formats preserve canonical values without unnecessary unpremultiply/reassociate loss. This also updates equality/hash behavior to compare canonical scaled values. SIMD helpers are split into `MultiplyAddEstimate` vs `FusedMultiplyAdd`, with byte-to-float normalization updated to match scalar rounding exactly across vector widths. JPEG converters, resize kernels, and Porter-Duff/associated-alpha blending paths were updated to use the appropriate helper for either fast estimate or strict fused rounding semantics. Tests were expanded substantially (including exhaustive component/alpha cases and fused-order checks), incidental test cleanup was applied, benchmark comment snapshots were refreshed, and one black/white reference output image was updated.	2 months ago
James Jackson-South	c4683902a4	Add associated-alpha pixel formats Introduce Rgba32P, Bgra32P, Argb32P, Abgr32P, NormalizedByte4P, and HalfVector4P. Add representation-aware scalar and bulk conversions, optimized pixel operations, and associated-alpha blending across all Porter-Duff modes. Include comprehensive conversion, layout, blending, and performance coverage.	2 months ago

Andreas	a76c02f7c0	Replace test image with a smaller one. Adjusted Identify_AnimatedPng_ReadsFrameCountCorrectly to expect 48 frames instead of 50.	5 months ago
Andreas Eriksson	ac1905328d	Fix Identify returning incorrect frame count for animated PNGs The Identify method had two bugs when processing fdAT (FrameData) chunks: 1. A spurious Skip(4) before SkipChunkDataAndCrc caused the stream to be misaligned by 4 bytes, since chunk.Length already includes the 4-byte sequence number. 2. Unlike Decode, which consumes all fdAT chunks for a frame in one shot via ReadScanlines + ReadNextFrameDataChunk, Identify processed them individually, calling InitializeFrameMetadata for each chunk and inflating the frame count. The fix removes the extra Skip(4) and adds SkipRemainingFrameDataChunks to consume all continuation fdAT chunks for a frame, mirroring how ReadNextFrameDataChunk works during decoding.	5 months ago
