Move the main target framework from net8.0 to net10.0 and the preview lane from net10.0 to net11.0, adding a global.json floor for SDK 10+ and updating CI coverage and test projects to match.
The change also adjusts hardware-intrinsic feature tests for .NET 11's x86-64-v2 baseline, updates Magick.NET, adds PDF files to LFS, and converts many internal helper and codec APIs from Span<T> to ReadOnlySpan<T> where inputs are not mutated.
Use tile width (instead of full image width) when creating T4/T6/Modified Huffman decompressors for tiled TIFF decoding, preventing row-size mismatches and false overrun failures. Also standardize the CCITT overrun error message and add regression coverage for both strip-based and tiled reporter samples that must throw when decoded pixels exceed image width.
The partners.adobe.com links for the TIFF 6.0 specification and Supplements 1 and 2 GET 404. Replace them with the equivalent PDFs hosted by download.osgeo.org (libtiff project), verified 200.

CubicResampler.Spline had a second XML summary copied from RobidouxSharp. The field is the B-spline (B=1, C=0) kernel, so only the spline summary should remain.

Adds explicit bounds checks before writing decoded CCITT runs in both T4 and Modified Huffman TIFF decompressors, preventing oversized runs from writing past the current row. Error messages were also standardized/capitalized for CCITT parsing failures. Includes new regression tests using compressed TIFF PoCs to verify decoding now throws ImageFormatException with the expected width-overrun message.
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.
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.
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.
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.
Route BlendWithCoverage calls through AssociatedAlphaPorterDuffFunctions when TOperator.IsAssociatedAlpha is true, across all SIMD widths (scalar, Vector256, Vector512) and all BlendWithCoverageFunction overloads.
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.
- Add ICO, CUR, and QOI encoder/decoder seeding in AotCompilerTools
- Introduce SeedPixelOperations() to explicitly seed all built-in pixel format PixelOperations<T> specializations for Mono WASM AOT
- Add [DynamicDependency] on Configuration constructors to keep the seed graph visible to .NET trimmers
- Add AI coding guideline files (AGENTS.md, CLAUDE.md, GEMINI.md, copilot-instructions.md)
- Update .gitattributes to treat .a, .dylib, and .so as binary
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.
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.
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.
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.
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.
