Golang GdkColorspace Examples

Example #1

File: gdk.go Project: raichu/gotk3

// PixbufNew is a wrapper around gdk_pixbuf_new().
func PixbufNew(colorspace Colorspace, hasAlpha bool, bitsPerSample, width, height int) (*Pixbuf, error) {
	c := C.gdk_pixbuf_new(C.GdkColorspace(colorspace), gbool(hasAlpha),

	if c == nil {

	}
	obj := &glib.Object{glib.ToGObject(unsafe.Pointer(c))}
	p := &Pixbuf{obj}
	runtime.SetFinalizer(obj, (*glib.Object).Unref)
	return p, nil
