Small [Go](http://golang.org) package for fast high-level image processing using [libvips](https://github.com/jcupitt/libvips) via C bindings, providing a simple [programmatic API](#examples).
bimg was designed to be a small and efficient library supporting common [image operations](#supported-image-operations) such as crop, resize, rotate, zoom or watermark. It can read JPEG, PNG, WEBP natively, and optionally TIFF, PDF, GIF and SVG formats if `libvips@8.3+` is compiled with proper library bindings.

It can read JPEG, PNG, WEBP natively, and optionally TIFF, PDF, GIF and SVG formats if `libvips@8.3+` is compiled with proper library bindings. Lastly AVIF is supported as of `libvips@8.9+`. For AVIF support `libheif` needs to be [compiled with an applicable AVIF en-/decoder](https://github.com/strukturag/libheif#compiling).
bimg is able to output images as JPEG, PNG and WEBP formats, including transparent conversion across them.
