[Git][wine/wine][master] windowscodecs: Decode GIF frames on demand.
Alexandre Julliard pushed to branch master at wine / wine Commits: c2f57082 by Zhengyong Chen at 2026-06-17T23:04:42+02:00 windowscodecs: Decode GIF frames on demand. The GIF decoder currently calls DGifSlurp() during initialization, which decodes and stores pixel data for every frame in the image. For animated GIFs with a large number of frames this can result in significant startup time and memory consumption, even when only a single frame is requested by the application. Change the decoder to scan GIF headers during initialization and defer frame pixel decoding until CopyPixels() is called for a specific frame. This avoids eagerly decoding unused frames while preserving existing decoder behavior.
