Hi all,
Is there anyone familiar with the use of xloadimage/xsetbg who
can
give me a hint as to why I can't load a small image with a transparent
background image onto an existing background image.
In the following bash shell function, virgin.jpg is intended to cover the
whole background, with one.jpg and two.gif being smaller images (edited with
the GIMP) with transparent backgrounds.
I can't seem to load an image with a transparent background onto an existing
root window with the transparent bit showing the original background image -
the transparent bits of one.jpg and two.gif always show white.
TIA for any assistance/suggestions
Andy
