I want to processing lots of image (scale it). so, create a pixbuf object in every thread to processing image.

srcPixbuf = new Pixbuf(/path/to/image/file);

resize image and save. after processing some image, program report OutOfMemory error.

I think, maybe need to free pixbuf object everytime. But, the method of free pixbuf object was not found. How to free a pixbuf object ?
