NEXT STEPS
The current focus would be applying refactors and optimizations from reviews, followed by completing the JPEG XL modular.
- Use Stream for Box Content Decoder
- Reduce errors in JxlDecoderCore
- Add GetStride method to JxlFrameDecoder
- Add JxlDctQuantWeightParameters and JxlQuantizerEncoding to implement more quant_weights.h components, and add proper documentation to each member of JxlQuantMode.
- Remove InlineArray2<T> (there's already one built into System.Runtime.CompilerServices, so prefer to use that)
Remove the `Numerics.Normalize` wrapper and call `TensorPrimitives.Divide` directly when normalizing resize kernels. This also drops the now-unused normalization test coverage and the redundant benchmark-only `System.Numerics.Tensors` package reference for net10.0.
Replaced ImageSharp’s custom TensorPrimitives_ and several Vector128/256/512 helper fallbacks with direct System.Numerics and System.Numerics.Tensors APIs across color conversion, codecs, filtering, blending, and convolution paths. Removed the obsolete compatibility helper files, updated package references (including System.Numerics.Tensors and newer System.IO.Hashing), and aligned tests with runtime behavior changes such as inverted float clamp bounds now throwing ArgumentException.
Replace the custom zlib deflate stack with `System.IO.Compression.ZLibStream`, and add `ChunkedWriteStream` to keep PNG/TIFF/EXR output framed in fixed-size segments. Update the affected compressors and tests to match the new streaming path.
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.
JxlBoxHeader contains a header for boxes in the JPEG XL container.
JxlFileTypeBox represents the ftyp box.
BinaryUtils contains helper methods to read/write primitives from/to Stream in custom endianness
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.
- Implemented decode.cc
- Added prototype of JXL image info
- Made JxlBitReader use ReadOnlyMemory
- Made changes to ICC codecs, changing accessibility of a few methods from private to internal and exposing IccDataReader's index
- Added JxlMemoryWriter as a MemoryAllocator alternative to MemoryStream
