PCB's netlist is readily available within pcb's innards, and easily parsable out of the *.pcb file. So far nobody's needed it so there's no command to extract it, that's all. If you have a specific format you need it in, your best choice is to write an exporter for it, then you can extract it wi

The last part of tracing is to write some kind of netlist or list of connections, which probably is pretty much the same as back-annotation. From what I find in the mailing list and the documentation, there is not very much support for this in pcb at the moment, or am I missing something. It obviou

Currently, it's just one background image, but you could change it to load two and switch between them depending on which side of the board you're looking at. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listi

I'm in the process of upping myself to the latest git version and without having had the possibility to play with the newest dev version, I would like to ask if it is possible to have a separate background image for each layer. I am repairing a pcb with top and bottom layer with fitted components a

Is it possible to import a bit map graphic, be it png, jpg, etc, and overlay it on a layer so you can then trace it using pcb? This way a scan acn be made of an existing pcb and accurately reproduced in pcb. tj ___ geda-user mailing list geda-user@
