WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools 'cwebp' and 'dwebp' to compress and decompress images respectively.

See https://developers.google.com/speed/webp for details on the image format.

Building

Zig version required is at least 0.12.0-dev.1808+69195d0cd. Build process for native target is just

zig build -Doptimize=ReleaseSmall

Consider specifying generic target for maximum compatibility, for example:

zig build -Dtarget=x86_64-linux

Pass option zig-decoder in order to use Zig port. If decoder is the only thing you'll need, you can use only-decoder option to deal only with Zig:

zig build -Dzig-decoder -Donly-decoder

Also see the general building documentation.

Encoding and Decoding Tools

The examples/ directory contains tools to encode and decode images and animations, view information about WebP images, and more. See the tools documentation.

APIs

See the APIs documentation, and API usage examples in the examples/ directory.
