libimlib2-dev - 1.7.1-2+deb11u1 main

Imlib2 is a library that does image file loading and saving as well as
rendering, manipulation, arbitrary polygon support, etc.
.
It does ALL of these operations FAST. Imlib2 also tries to be highly
intelligent about doing them, so writing naive programs can be done easily,
without sacrificing speed.
.
This package provides the development files (ie. includes, static library,
manual pages) that allow one to build software which uses imlib2.
