Release Notes

Version 0.2.1

Changes:

Increased the required Rust compiler version to v1.80

Optimizations:

Removed bounds checks from hot loops in read_coefficients() (#121)
Faster YUV -> RGBA conversion for a 7% speedup on lossy RGBA images (#122)
Faster alpha blending for up to 20% speedup on animated images (#123)
Much faster arithmetic decoding for up to 30% speedup on lossy images (#124)
Avoid unnecessarily cloning image data for a 4% speedup (#126)

Version 0.2.0

Breaking Changes:

WebPDecoder now requires the passed reader implement BufRead.

Changes:

Add EncoderParams to make predictor transform optional.

Bug Fixes:

Several bug fixes in animation compositing.
Fix indexing for filling image regions with tivial huffman codes.
Properly update the color cache when trivial huffman codes are used.

Optimizations:

Substantially faster decoding of lossless images, by switching to a table-based Huffman decoder and a variety of smaller optimizations.

Version 0.1.3

Changes:

Accept files with out-of-order "unknown" chunks.
Switched to quick-error crate for faster compliation.

Bug Fixes:

Fixed decoding of animations with ALPH chunks.
Fixed encoding bug for extended WebP files.
Resolved compliation problem with fuzz targets.

Optimizations:

Faster YUV to RGB conversion.
Improved BitReader logic.
In-place decoding of lossless RGBA images.

Version 0.1.2

Export decoder::LoopCount.
Fix decode bug in read_quantization_indices that caused some lossy images to appear washed out.
Switch to byteorder-lite crate for byte order conversions.

Version 0.1.1

Fix RIFF size calculation in encoder.
