I have been experimenting with high resolution pictures rendered by the gra- phics hardware of a GL4DVGX-3.3. Based on the original values for the window- command I changed left, right, top and bottom accordingly to get the subframes. This didn't quite work as intended. The subimages often didn't fit perfectly and there were visible seams. I could get rid of these seams by correcting left and/or right and/or top and/or bottom by a 0.5 pixels. But I could never figure out in advance where corrections were ( not ) necessary. Is there a way to get rid of these seams without correcting left,right,top, bottom or to find out what to correct without lengthy experiments? I used subpixel ( TRUE ), glcompat ( GLC_OLDPOLYGON, 0 ) and antialiasing with the accumulation-buffer. Thanks in advance! M.H.
