jxl-oxide v0.4.0

Version 0.4.0 of jxl-oxide improves memory usage with updated frame renderer, and features cropped decoding.

Cropped decoding

jxl-oxide now supports rendering only part of the image. A region of interest can be specified using --crop option of jxl-dec since jxl-oxide-cli 0.2.3, or CropInfo struct in jxl-oxide. The renderer will only decode necessary parts of the bitstream.

Note that the syntax of --crop is unstable and subject to change.

Breaking changes

• PassGroup and HfCoeff are removed. Instead, they are decoded into grids directly.
• Frame decoding is rewritten; interface of jxl_frame::Frame has changed.
• jxl_render and jxl_oxide methods now accept crop regions.
• jxl_oxide::JxlRenderer is merged into jxl_oxide::JxlImage.
• ImageMetadata::apply_orientation now accepts signed coordinates instead of unsigned ones.
• is_delta_palette method is replaced with is_palette.
