Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/imlib2-xlib|the CHICKEN 5 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. == Description CHICKEN Scheme bindings for Imlib2's Xlib API. For source code, bug reports, and feature requests, visit the [[https://github.com/retroj/imlib2-xlib-egg|github project page]]. == Authors * John J Foerch == Requirements === Chicken eggs * [[foreigners]] * [[imlib2]] === C headers * imlib2 development headers * X11 development headers (libx11-dev) == API === Datatypes Image creation procedures return an imlib2 egg `image` record, and image operators expect one of these objects as their first argument.
