Hi! Please read the note below.
Aside from the median cut quantizer, this code has been merged into the Go standard library. I would strongly encourage you to use that instead :).

Functions ¶
func Decode ¶
Decode reads a GIF image from r and returns the first embedded image as an image.Image.
func DecodeAll ¶
DecodeAll reads a GIF image from r and returns the sequential frames and timing information.
func DecodeConfig ¶
DecodeConfig returns the global color model and dimensions of a GIF image without decoding the entire image.
Types ¶
type MedianCutQuantizer ¶
type MedianCutQuantizer struct {
NumColor int
}
MedianCutQuantizer constructs a palette with a maximum of NumColor colors by iteratively splitting clusters of color points mapped on a three-dimensional (RGB) Euclidian space. Once the number of clusters is within the specified bounds, the resulting color is computed by averaging those within each grouping.
