x-ege/xege

How x-ege/xege works

EGE is a cross-platform C/C++ graphics library with a beginner-friendly, BGI-like API. Its main workflow is an application opening a graphics window, issuing drawing or image operations, handling input, and presenting pixels through a native platform backend. Separate capabilities include image loading and transformation, text, input, camera capture, and music. The README documents the platform backends and broader feature set; sampled source confirms image operations and native render-target behavior, but does not expose all dispatch wiring, so uncertain links are omitted.
