GIF encoder written in C (shared library)

Fast and lightweight GIF encoder that can create GIF animations and images. Summary of the main features: - user-defined global or local color-palette with up to 256 colors (limit of

  the GIF format)

- size-optimizations for GIF animations:

  - option to set a pixel to transparent if it has identical color in the
    previous frame (transparency optimization)
  - do encoding just for the rectangular area that differs from the previous
    frame (width/height optimization)

- different options for GIF animations: static image, N repetitions,

  infinite repetitions

- user-defined delay time from one frame to the next (can be set

  independently for each frame)
