libsquish is a small, portable C++ library for compressing and decompressing images with the DXT standard (also known as S3TC or BC). This standard is mainly used by OpenGL and DirectX for the lossy compression of RGBA textures..
This project provides Go bindings for libsquish. go-squish also provides a patch file that adds a C compatibility wrapper to libsquish, since Go doesn't support C++ libraries directly. Apply it before compiling the library. It is compatible with libsquish version 1.15.
go-squish uses the system version of the static libisquish library. More information about how to build libimagequant can be found in the libisquish readme.
go-squish package path is currently github.com/InfinityTools/squish. The bindings can be built via go build.
This package makes use of CGO, which requires a decent C compiler to be installed. However, using go install removes the C compiler requirement for future invocations of go build.
