James Jackson-South	ad12d7a4bb	Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>	1 week ago
James Jackson-South	c9af728104	Add plus and extended pixel blend modes Introduce the `Plus` alpha composition mode and add support for ColorDodge, ColorBurn, SoftLight, Difference, Exclusion, Hue, Saturation, Color, and Luminosity across straight-alpha and associated-alpha pixel blenders. The generated blender/function tables and selector logic were updated to expose the new combinations, and tests were expanded to cover mode mapping, expected blend results, and parity between straight and premultiplied alpha paths.	1 week ago
James Jackson-South	b81b9a2792	Use associated alpha blending with coverage Route BlendWithCoverage calls through AssociatedAlphaPorterDuffFunctions when TOperator.IsAssociatedAlpha is true, across all SIMD widths (scalar, Vector256, Vector512) and all BlendWithCoverageFunction overloads.	2 weeks ago
James Jackson-South	3c3d523954	Flatten pixel blender hierarchy	3 weeks ago
James Jackson-South	1c726da0df	Clean up normalized SIMD pipelines	3 weeks ago
James Jackson-South	501afd48c1	Normalize stateful Vector4 transforms	3 weeks ago
James Jackson-South	873c64ec12	Normalize pixel blending SIMD traversal	3 weeks 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.	4 weeks ago
James Jackson-South	c1449ebeb2	Update AssociatedAlphaPixelTests.cs	4 weeks 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.	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.	4 weeks 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.	1 month 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.	1 month ago
