Example #1

File: image.go Project: cannonhuang/nephele

/*
GetFormat() return format of this image
*/
func (this *Image) GetFormat() (string, error) {
	var err error = nil
	tran := this.Cat.NewTransaction("GraphicsMagickCmd", "GetFormat")

		err = errors.New(fmt.Sprintf("error get image format: %s (ExceptionType = %d)", C.GoString(descr), etype))
		return "", err
	}
	return C.GoString(format), nil

func (self *Canvas) Format() string {
	ptr := C.MagickGetImageFormat(self.wand)
	defer C.free(unsafe.Pointer(ptr))

	return C.GoString(ptr)
}

Example #3

File: canvas.go Project: Yuras/canvas

// Returns image format
func (self Canvas) Format() string {

/* Gets the format of a particular image in a sequence. */
func (w *MagickWand) ImageFormat() string {
	return C.GoString(C.MagickGetImageFormat(w.wand))
}

Example #5

File: canvas.go Project: vuleetu/canvas

func (cv Canvas) Format() string {
	format := C.MagickGetImageFormat(cv.wand)
	return strings.Trim(C.GoString(format), " ")
}
