GdkPixbuf containing a copy of src scaled to
dest.width x dest.height. Leaves src unaffected. interp.type
should be GDK_INTERP_NEAREST if you want maximum speed (but when
scaling down GDK_INTERP_NEAREST is usually unusably ugly). The
default interp.type should be GDK_INTERP_BILINEAR which offers
reasonable quality and speed.gdkPixbufScaleSimple(object, dest.width, dest.height, interp.type)dest.widthdest.heightinterp.typeGdkInterpType] the interpolation type for the transformation.src by creating a sub-pixbuf
pointing into src; see gdkPixbufNewSubpixbuf.
For more complicated scaling/compositing see gdkPixbufScale
and gdkPixbufComposite.
