Performance

This Program grew out of the pain, that most GIF-Viewer consume quiet some CPU time, so having a GIF as wallpaper somewhat drained the battery. XRootGIF tries to minimize CPU time used to display fancy GIFs, by pre rendering all frames and allocating them in the X-Display instance. Some GIFs may still make your PC heat your room, but this can be avoided by using the performance mode, which will simply downscale the framerate.

Planned features

• more image fitting modes
• configuration files
• other animation formats (webm, apng, ...)

Building

The following libraries are used by XRootGIF:

• libx11
• giflib
• imlib2
• (libXrandr)

Tools:

• gcc
