We have a program that works fine in NeWS 1.1 but barfs in OpenWindows. The problem is as follows: We create an offscreen "buffer" canvas. We proceed to draw to this canvas and then use imagecanvas to copy the contents of the buffer to an onscreen ClientCanvas. In OpenWindows this simply does not work. Imagecanvas works when used with a canvas generated with readcanvas, but breaks with any other canvas. In dumping the canvas created by readcanvas the field orphaned is true. There seems no way for me to create an orphaned canvas though. Am I missing something? A while back we posted a message about fill and stroke being broken in OpenWindows. The replys I received could not duplicate the problem. We have pinpointed the problem, fill and stroke do not implicitly do a newpath as they should. Thanks to all who sent messages.
