Types

type GIF

type GIF struct {
	Image     []*image.Paletted // The successive images.
	Delay     []int             // The successive delay times, one per frame, in 100ths of a second.
	LoopCount int               // The loop count.
}

GIF represents the possibly multiple images stored in a GIF file.

func DecodeAll

func DecodeAll(r io.Reader) (*GIF, error)

DecodeAll reads a GIF image from r and returns the sequential frames and timing information.
