Category: Gerber Parser Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Sebastian (gustep12) Assigned to: Julian Lamb (thepurlieu) Summary: gerv-2.5.0 aperture macro problem Initial Comment: I had some gerber files here which were displayed incorrectly in v2.5.0 and also v2.4.0. I spent some hours trying to figure out where the problem occurred, until I determined that it must be related to the following aperture macro statement: %AMROTRECT*21,1,$1,$2,0,0,$3*% This macro is apparently used to define "rotated rectangle" apertures like this: %ADD21ROTRECT,0.087X0.087X270*% %ADD26ROTRECT,0.084X0.084X180*% Any aperture based on this macro was not parsed correctly. I know that rotations occur only at 90 degree intervals in the file in question, so I was able to fix the RS-274X file by converting the offending (rotated rectangle) statement to a normal rectangle macro like this, by swapping the width for the height. This works for 90 and 270 degree rotations, while for 180 degree rotated rectangles I just converted them to normal rectangles without swapping X and Y: %ADD21R0.087X0.087*% %ADD26R0.084X0.084*% However, a better fix would be to ensure that the macro in question works as intended to begin with... Just trying to be helpful. Thanks very much for releasing v2.5.0!

In "fast" rendering modes everything looks o.k., but in "normal" and HQ modes the file which I attached looks messed up. See the following two screenshots: gerbv250problem_fastrender.png gerbv250problem_normalrender.png Sebastian ---------------------------------------------------------------------- Comment By: Julian Lamb (thepurlieu) Date: 2011-01-20 06:14 Message: Sebastian, Thanks for the detailed report. Unfortunately, I can't seem to see the problem on my machine. Could you possibly attach a screenshot zooming in on the erroneous rendering portion? Also, are you using the Windows version or Unix version?
