aM,
Thanks for spotting this problem...I guess I missed updating the
example files when we changed the API previously. I went ahead and
fixed it all in git, so please update your tree and check out the
changes. Basically, pass NULL in for the transform and the function
will just use the default identity transform. I think I checked all 6
of the examples and they should work now. Let me know if you find
otherwise, and feel free to ask any questions regarding libgerbv...we're
glad to help!
Cheers--
Julian

Julian,
Thanks for the prompt reply. Ive finally installed all the
dependencies and was able to build it from source.
I ran into problems with examples 1, 2, 4, 5. All the same thing:
example5.c:56: error: too few arguments to function
‘gerbv_export_rs274x_file_from_image’
looks like a transform is missing. Whatś a quick way to get this working?
Thanks again, it looks like this library will be perfect.

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
