Oh, dear. :-(

You might have a look at ZIMAGE. It might even do exactly
what you are trying to do. You *definitely* need to know
what window is the current graphics window (the one you
will be drawing into) in a widget program. You do it
by doing a WSET to the window index number. This number
is the *value* of the draw widget:

Widget_Control, drawWidgetID, Get_Value=wid
WSet, wid

Cheers,

David
