There are a number of issues here that I can clarify.
First, Electric is not dependent on NetBeans at all. Sure, NetBeans
can be used to do development, but so can Eclipse. You can also build
Electric without any IDE, just using the command line.
Second, if you have changes to submit to Electric, the development
team prefers that you EMail us about it directly, and we will be able
to discuss with you the proper way to get these changes into the repository.
Third, Electric already has an automatic way to generate images from
every cell in a library, but that image generator is PostScript. The
PS output code has an option to produce a current set of PS files for
every cell in a library. The code can even compare PS file dates with
Electric cell dates, and rewrite the PS of cells that have changed
since the PS was generated.
If you want to extend this code to PNG or some other format, it is
doable. Yes, the internal code makes reference to many other classes
in Electric. No, you don't have to worry about VarContext objects.
They are used to define a path through the hierarchy. As you traverse
down the circuit hierarchy, VarContext objects remember where you
came from. This helps only in rare situations where there are
parameterized cells. However, none of this is relevant when you are
just printing individual cells.

Its been a while, I sorta let this problem get dusty. I'm working on
it again, this time in Java (seems easier to get what I want done).
If there already is some easy way to export all the cells in a
library as a png, for example, I'd appreciate knowing. There may
still be a problem with images being drawn directly from the screen;
I'd like to avoid cycling all the cells, even programmatically, to
do image exports.
If I come up with a fix, I'd like to contribute back to the
community, I think better reporting skills would benefit the program.
My biggest question currently would be what sort of gui form it
would be acceptable to utilize. Electric seems to be mainly done in
Netbeans; If I were to use another toolkit for graphical layout
management, would it be acceptable. I was rather hoping not to
download Netbeans ... again ... after having uninstalled it.

Odd thing is it seems the best way to do this is by using classes in
the com.sun.electric.tools.ui package, which seem to define a bunch of
private internal classes just to draw some stuff on a 2D/3D canvas and
render an image out.
Is there perhaps a more straightforward, sane route to take? I suppose
I might have better luck with PostScript output, and just write a bash
script to do ps to png conversion...though it seemed like even that
was un-necessarily complex as it needed a bunch of VarContext stuff,
which, having just jumped into the source, I don't have a clue what
they are, or where to get one (properly).
Just looking for pointers, I might come up with a solution myself.
