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.	3 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

Stefan Nikolei	7b4615f70c	Add ARM hosted runners Added macos-26 and ubuntu-2204 github runners which run on arm Use Tolerant ImageComparer We now use the tolerant Image Comparer for now. Disable Tests which need libgdiplus This disables all tests which need libgdiplus for macs with arm. The hosted runners do not have libgdiplus installed Install libgdiplus on mac Enable disabled tests on arm Try to create symlink Try without fallback path Skip on linux This was removed by mistake Remove whitespace	9 months ago
