Probably you should look at glwh These examples have saves too http://www.jsoftware.com/jwiki?action=fullsearch&value=glwh&context=180&fullsearch=Text
But between glwh (or other showing) and capturing (glqall) there need to be events processing, as Bill said. Maybe "msgs" (or so) from wd would be helpful, or forcing viewmat to render--a "show" verb like in plot. --- Devon McCormick <[EMAIL PROTECTED]> wrote: > Members of the forum - > > I'm experimenting with saving bitmaps generated by "viewmat".
