Types ¶
type AggregationType ¶
type AggregationType uint8
AggregationType specifies the type of aggregation to be done
const ( // Mode - pick the highest priority value Mode AggregationType = iota // Mean - weighted average all values Mean )
type MedianCutQuantizer ¶
type MedianCutQuantizer struct {
// The type of aggregation to be used to find final colors
Aggregation AggregationType
// The weighting function to use on each pixel
Weighting func(image.Image, int, int) uint32
// Whether to create a transparent entry
AddTransparent bool
}
MedianCutQuantizer implements the go draw.Quantizer interface using the Median Cut method
Example ¶
file, err := os.Open("test_image.jpg")
if err != nil {
fmt.Println("Couldn't open test file")
return
}
i, _, err := image.Decode(file)
if err != nil {
fmt.Println("Couldn't decode test file")
return
}
q := MedianCutQuantizer{}
p := q.Quantize(make([]color.Color, 0, 256), i)
fmt.Println(p)
