James Jackson-South	0df7ccaa61	Make MemoryAllocator limits configurable and extensible The allocation limits on MemoryAllocator were internal with no public way to raise the 1 GB single-buffer default, and ApplyOptions was not callable from external subclasses, which blocked custom allocators. - Expose MemoryGroupAllocationLimitBytes, SingleBufferAllocationLimitBytes, and AccumulativeAllocationLimitBytes with validated protected setters. - Make ApplyOptions protected so derived allocators can accept options. - Add MemoryAllocatorOptions.SingleBufferAllocationLimitMegabytes to raise the contiguous buffer cap up to 2047 MB without a custom allocator. - Add public-api tests that implement a complete external allocator. - Add behavior tests for the new option and its validation.	6 days ago

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.	6 days 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	6995704190	Remove AntialiasThreshold from GraphicsOptions Drops the `AntialiasThreshold` field/property from `GraphicsOptions` and updates related XML docs to reflect the simplified antialiasing behavior. Clone logic and test coverage were adjusted accordingly, including removal of threshold assertions and comparer checks.	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	ed64ea7197	Reject ICO entries at stream-end offset Tightened icon frame bounds validation to treat `ImageOffset == available` as invalid, preventing non-empty resources from starting at the exclusive end of the icon stream. Added a regression test that mutates an ICO directory entry to this boundary value and verifies both `Decode` and `Identify` throw `InvalidImageContentException` with the expected message.	2 weeks 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.	3 weeks 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.	3 weeks 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.	3 weeks 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.	3 weeks ago
