func main() {
	imagick.Initialize()
	defer imagick.Terminate()

	mw := imagick.NewMagickWand()
	defer mw.Destroy()

	if err := mw.ReadImage("2015-09-11_15-34-51.jpg"); err != nil {
		panic(err.Error())
	}

	w := mw.GetImageWidth()
	h := mw.GetImageHeight()

	if err := mw.ResizeImage(w/10, h/10, imagick.FILTER_LANCZOS, 1); err != nil {
		panic(err.Error())
