)
func init() {

}
func main() {
imgfile, err := os.Open("./img.png")
if err != nil {
fmt.Println("img.png file not found!")
os.Exit(1)
}
defer imgfile.Close()
img, _, err := image.Decode(imgfile)
fmt.Println(img.At(10, 10))
bounds := img.Bounds()
fmt.Println(bounds)
canvas := image.NewNRGBA(bounds) // <-- here
stride := canvas.Stride
fmt.Println("Stride : ", stride)
}
