Package image defines the Image
interface:
package image type Image interface { ColorModel() color.Model Bounds() Rectangle At(x, y int) color.Color }
(See the documentation for all the details.)
Also, color.Color
and color.Model
are interfaces, but we‘ll ignore that by using the predefined implementations color.RGBA
and color.RGBAModel
. These interfaces and types are specified by the image/color package
package main import ( "fmt" "image" ) func main() { m := image.NewRGBA(image.Rect(0, 0, 100, 100)) fmt.Println(m.Bounds()) fmt.Println(m.At(0, 0).RGBA()) }
