Hi John, In my git-ified pcb repo I have: <quote> Author: danmc <danmc> Date: 01/03/2008 12:45:12 AM Parent: change the preprocessor logic a bit to avoid #ifdef-ing i... Child: apply patch 1852864 GTK HID: scrolled layer preferences Branch: master (Display nets as a hierarchical tree in the netlist window.) origin (Display nets as a hierarchical tree in the netlist window.) Branch: pcb-20080202 (set version for 20080202 release) Follows: pcb-20070912-base (news for 20070912) Precedes: pcb-20080202-base (update for 20080202)
Fix a problem with the X-Y output file where the y values were mirrored and offset with respect to the RS274-X output. Given that this bug has been here since the code was written 3 years ago, I conclude that in fact no one has used this feature. </quote> also look at: http://archives.seul.org/geda/user/Jan-2008/msg00016.html Kind regards, Bert Timmerman.
