I am having problems with the GMR_$PRINT_DISPLAY routine of the GMR3D package. The problem is that since I changed over from GMR3D 2.5 to GMR3D 2.7 this routine stoped functioning as it used to. My display contains two overlapping viewports and everything gets properly draw by the GMR_$DISPLAY_REFRESH routine; at the bottom the first viewport and on top the second viewport. In the days of GMR3D 2.5 everything was printed correctly by GMR_$PRINT_DISPLAY. Now, however, only the bottom (the first) viewport gets draw in the color white (1.00 setgray). This gives an invisible picture. Now I noticed that there are new routines that handled the transparency of the background and the drawing order of overlapping viewports. Making the top viewport's background transparent resulted in a visible drawing on paper of the first viewport (0.00 setgray). The top viewport, however, still does not get drawn. Is this a bug in GMR_$PRINT_DISPLAY or is there something else that I have to do to get the top viewport drawn too. -- Fons Rademakers. -- Org: NIKHEF-H, National Institute for Nuclear and High-Energy Physics.
