Werner,
Just to finish up the earlier agg discussion - I got all three
backends working and tested (including agg with wxImage) in the code
I attached to my last message.

I suggest that it should be in a separate file from the existing
python bindings. The reason is that if you are writing a non-wxpython
app in python, you don't want plplot to load wx, which would slow down
loading and could even conflict with another toolkit (such as pyQT or
Tkinter). If you import the plplot-wxpython bindings, you won't
usually need to separately import the plplot-python bindings.

In python, you can check for wxpython with something like:
try:
import wx
except ImportError:
# wxPython not found
pass
else:
# wxPython found
pass
where you replace the pass statements with whatever you want done in
those cases. Note that nothing extra should need to be compiled for
the wxpython driver, since it is all in pure python (assuming the
plplotcapi.i changes are always included).
One more item: I noticed that the plplot python files use a mix of
tabs and spaces for their indentation, which is generally considered a
bad thing. I found that the example files could be converted to all
spaces with:
"sed 's/\t/ /g' oldfile.py >newfile.py"
although in general you may have to change the number of spaces that
the tab is replaced with.
My next question is perhaps more problematic: is there a chance of
regular releases of a windows build of plplot in the future? Now that
it is working so well for me, I would really like to use plplot from
wxpython in windows, but I have no experience building on windows or
cross-compiling. Probably this is a discussion for a new thread...
I noticed Alan just responded to the last email, but I am sending this
anyway because it looks like we are basically in agreement.
Thanks,
Brian
