gdk-pixbuf:pixbuf-loader-set-size (loader width height)

loader -- a gdk-pixbuf:pixbuf-loader object
width -- an integer for the desired width of the image being loaded
height -- an integer for the desired height of the image being loaded

Causes the image to be scaled while it is loaded. The desired image size can be determined relative to the original size of the image by calling the gdk-pixbuf:pixbuf-loader-set-size function from a signal handler for the "size-prepared" signal.

Attempts to set the desired image size are ignored after the emission of the "size-prepared" signal.
