Full Changelog: 0.7.0...0.7.1

jxl-oxide v0.7.0

Version 0.7.0 of jxl-oxide is mainly about optimizations and fixing bugs in edge cases. Some notable changes are:

WebAssembly bindings

jxl-oxide-wasm, WebAssembly bindings to jxl-oxide, is published to NPM. For now, it's a very simple package which can decode JPEG XL image to PNG. Demo can be found at tirr-c/jxl-oxide-wasm-demo.

16-bit Modular buffers

JPEG XL image can signal whether 16-bit buffers are sufficient to hold all Modular sub-images¹. jxl-oxide can now allocate smaller buffers when 16-bit buffers are sufficient.

---

Changed

• jxl-modular: Modular 16-bit buffers by @tirr-c in #207
• jxl-render: Defer blending by @tirr-c in #211
• jxl-render: Save blend result to shared cache by @tirr-c in #212

Added

• Add WebAssembly demo by @tirr-c in #223

Fixed

• Fix Modular ec_upsampling handling by @tirr-c in #248
• Fix various panics found by fuzzing

Full Changelog: 0.6.0...0.7.0

1. Modular sub-images are used not only in lossless Modular images, but also in lossy VarDCT images to store 8x subsampled LF images, HF metadata information etc. ↩
