Message : Import graphics/cgif, from Brad, ok sthen CGIF is a 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) - fast: a GIF with 256 colors and 1024x1024 pixels can be created in below 50 ms even on a minimalistic system - MIT license (permissive) - different options for GIF animations: static image, N repetitions, infinite repetitions - additional source-code for verifying the encoder after making changes - user-defined delay time from one frame to the next (can be set independently for each frame) - source-code conforms to the C99 standard
