How to create GIF buttons.

If you want to create your own GIF buttons with a Motif look - and you have Tcl/Tk installed you can use the following procedure :
% wishx
whishx> button .b -text "Example" -bg gray
whishx> pack .b
... And from a different window ...
% xwd | xwdtopnm | ppmtogif > example.gif
- And click on the Tcl/Tk button you just created.

If you want your button to have transparent background ( - so it also looks nice on browsers that doesn't have gray background ), you can use the following procedure :

% xv example.gif  # Find color map entry # for bg col (starting with 0)
% gif-trans -t # example.gif > example_btn.gif
