I just checked in my correction to the rendering of rounded rectangles in PCB. This is one of the issues I discovered while investigating the polygon crashes with "GPS_BUG.PCB". The code to make rounded corners for clearing polygons had an off-by-one error. This caused rounded rectangles (such as the holes in copper planes for square pads) to be slightly twisted. The very-slightly-off-vertical and -horizontal lines this created were part of the issue with the crashes (caused by the internal polygon code suffering from roundoff errors when intersecting with such lines).
You can see an animation I made to show the before/after at: http://ad7gd.net/geda/roundrectanim.gif Red is "before" and blue is "after". You can see how the red version's rounded corner is not "centered" on the corner, and how the whole thing is twisted slightly clockwise. There are similar effects around traces which plow through polygons. Since PCB recomputes these clearances every time you load a board, this will affect any saved boards that you load. That's the main reason I waited for Dan to make a release before this commit. Please let me know if you see any problems with existing boards. -- Ben Jackson AD7GD <[EMAIL PROTECTED]> http://www.ben.com/ _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
