# Changelog

## @jsquash/png@3.1.1

### Fixes

- Fixes the type definitions for the `encode` and `decode` methods to work correctly with the intended bitDepths.

## @jsquash/png@3.1.0

### Added

- Added `bitDepth` option to `decode` method to allow decoding of 16-bit PNGs to their 16-bit RGBA values
- Added `encode` method to allow encoding of 16-bit RGBA image data
    - A Uint16Array is required for the pixel data when `bitDepth` is set to 16

## @jsquash/png@3.0.1

### Fixes

- Fixes the decoding of PNG images using non-rgba color types.

## @jsquash/png@3.0.0

### Breaking Changes

- `encode` method now returns an `ArrayBuffer` which matches the return type of other jSquash `encode` methods
- Ignores checksum errors. Allows images with invalid header chunks to be decoded (Fixes [#44](https://github.com/jamsinclair/jSquash/issues/44))
- Upgrades codec to image-png 0.17.10 (increases wasm file size by 54KB)
- Codec wasm and js files moved to /codec/pkg dir (due to addition of Rust source)
    - If you are accessing the wasm file by path you'll need to update your paths to reference `node_modules/@jsquash/png/codec/pkg/squoosh_png_bg.wasm`. It's now nested in the `pkg` dir.
