winscripter	064376a9f2	Add quantized spline implementations	2 months 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

winscripter	ac1c866e5a	Add xorshift implemetation	2 months ago
winscripter	487410e55f	Implement field encodings, move IJxlFields This is an implementation of field_encodings.h. Note that I avoided implementing EnumValid() and Values() functions, as we have dedicated methods in .NET to do exactly that (Enum.IsDefined, Enum.GetValues)	2 months ago

winscripter	6fea920e7f	Add metadata models	2 months ago
winscripter	21ff33f23c	Implement image and memory buffers Implementation of image.h and image.c; AC strategy implementation was slightly adjusted to reduce errors.	2 months ago
winscripter	31b5505d89	Implement JxlMemoryManager For now JxlMemoryManager will be a wrapper around MemoryPool<T>.	2 months ago
winscripter	1ac6140535	Implement AC strategy Implementation of ac_strategy.h and ac_strategy.c	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

James Jackson-South	5a0a74fecc	Merge pull request #3152 from SixLabors/js/fix-convolution-small-bounds Fix convolution sampling for bounds smaller than the kernel radius	2 months ago
James Jackson-South	0b685ab034	Fix convolution sampling for bounds smaller than the kernel radius KernelSamplingMap.CorrectBorder sliced the offset span by radius * kernelSize, so bounds narrower than the kernel radius threw ArgumentOutOfRangeException (GaussianBlur of a 130x8 region with sigma 10, for example), and bounds exactly equal to the radius let Bounce offsets escape the sampling range by folding an overshoot of a full extent to min - 1. Route bounds no larger than the radius through an exact per-mode correction that folds each offset into range: clamp for Repeat, periodic reflection for Mirror and Bounce, and true modulo for Wrap. The single-pass corrections are unchanged for larger bounds.	2 months ago
