When you use -windowhide, the first time that the view actually gets drawn internally is when you call the save bitmap command. The first time the view is drawn, it re-initializes the setting to the default, wiping out any changes that you might have made. I need to figure out some kludge to get around this. In the mean time, the best thing to do is just to run without -windowhide if you want to programmatically make bitmaps. Otherwise, doing something like saving the bitmap, doing your settings, then saving a second time would probably work inside -windowhide.
