TGIFImage is a TFPImageBitmap descendant which implements support for the GIF (Graphics Interchange Format) image format. GIF images support up to 8 bits per pixel in the image data, and a color palette of up to 256 colors from the 24-bit RGB color space. While GIF images allow animation, the LCL implementation does not support the feature.
