Not quite.

You use gdk_pixbuf to load a file.  The load function returns a pointer to
a GdkPixBuf struct.

Then, you determine if the picture has an alpha channel, and call the
appropriate gdk_rgb call.

Example code for this is in the gdk-pixbuf CVS module.  Look at
testpixbuf.c.  And yes, this is quite fast.
