Hi aM,
It depends on how in-depth you want to go. We have split out
"libgerbv" as a separate library you're welcome to use in your own
applications. If you download the gerbv source from git (see webpage on
how to do this), look at the /doc/example-code/ directory for a bunch of
examples on making some command line apps using libgerbv. The rendering
code is also accessible with libgerv, so you can make fully functional
GUI apps with it too.
If you want to just use the regular gerbv program and add some
specialized functions of your own, that would be another option. Go to
/src/interface.c to add any buttons or menu entries you want to add, and
then place the callbacks for those buttons in the /src/callback.c file.
You can then put whatever code you want in those callback stubs.
There's an example in /doc/example-code on how to draw rectangles. For
zooming to specific levels, you'll probably just want to look at the
functions in callbacks.c on how to do that.
Hack away!

Hello,
Im wondering how it would be possible for me to zoom in on a certain
region or a drawing that is specified by typing in (x, y, width,
height) parameters. Another use case would be to draw a box or circle
based on the above parameters.
Where would i start to be able to do something like this?
In general, how scriptable is gerbv? how can i start hacking?
thanks,
aM
