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
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

If you wanted to extract the as-built connectivity from a layout
(possibly one without a netlist specified in the PCB file), one
would have to re-construct a new netlist by tracking connectivity as
per the F key to find connected copper.
I would think PCB would already have one of those,

This is the thing I am looking for. I'll look into the code once I
manage
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
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

It should load PNG fine as well... (certainly the GTK HID can), and
probably other formats supported by gdkpixbuf, such as JPEG.

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.
