Exported Type Names

type GIF (struct) GIF represents the possibly multiple images stored in a GIF file. BackgroundIndex is the background index in the global color table, for use with the DisposalBackground disposal method. Config is the global color table (palette), width and height. A nil or empty-color.Palette Config.ColorModel means that each frame has its own color table and there is no global color table. Each frame's bounds must be within the rectangle defined by the two points (0, 0) and (Config.Width, Config.Height). For backwards compatibility, a zero-valued Config is valid to pass to EncodeAll, and implies that the overall GIF's width and height equals the first frame's bounds' Rectangle.Max point. // The successive delay times, one per frame, in 100ths of a second. Disposal is the successive disposal methods, one per frame. For backwards compatibility, a nil Disposal is valid to pass to EncodeAll, and implies that each frame's disposal method is 0 (no disposal specified). // The successive images. LoopCount controls the number of times an animation will be restarted during display. A LoopCount of 0 means to loop forever. A LoopCount of -1 means to show each frame only once. Otherwise, the animation is looped LoopCount+1 times. func DecodeAll(r io.Reader) (*GIF, error) func EncodeAll(w io.Writer, g *GIF) error
type Options (struct) Options are the encoding parameters. Drawer is used to convert the source image to the desired palette. draw.FloydSteinberg is used in place of a nil Drawer. NumColors is the maximum number of colors used in the image. It ranges from 1 to 256. Quantizer is used to produce a palette with size NumColors. palette.Plan9 is used in place of a nil Quantizer. func Encode(w io.Writer, m image.Image, o *Options) error
Exported Values
func Decode(r io.Reader) (image.Image, error) Decode reads a GIF image from r and returns the first embedded image as an image.Image.
func DecodeAll(r io.Reader) (*GIF, error) DecodeAll reads a GIF image from r and returns the sequential frames and timing information.
func DecodeConfig(r io.Reader) (image.Config, error) DecodeConfig returns the global color model and dimensions of a GIF image without decoding the entire image.
const DisposalBackground = 2 Disposal Methods.
const DisposalNone = 1 Disposal Methods.
const DisposalPrevious = 3 Disposal Methods.
func Encode(w io.Writer, m image.Image, o *Options) error Encode writes the Image m to w in GIF format.
func EncodeAll(w io.Writer, g *GIF) error EncodeAll writes the images in g to w in GIF format with the given loop count and delay between frames.
