Hello,
welcome everybody. I am new to Inkscape and this list.
:)
Let me explain my situation. I am an electrical
engineer and currently working towards my PhD degree,
for that reason I am using LaTeX very often. Since the
very first moment I had a problem to find a proper
application to create vector-based graphics in a
convenient way. The special problem is that the labels
in the graphics should use the LaTeX fonts and macros
that I use in my paper.
The only application that supports this (up to my
knowledge) is XFig. The vector based graphics itself
are being exported as Postscript or PDF. An additonal
LaTeX file containing the labels is generated that
includes the PS/PDF graphics file. At compile-time,
LaTeX puts the text above the PS/PDF graphics, just at
the position where it should be. - That is just a
great for me (and a lot of others I know)!
The problem with XFig is the following:
- Usability (argh!)
- Portability (at work I have Windows, I did not find
a proper Version of XFig, JFig that did the same job
as it does on my Mac)
Form what I have seen from Inkscape it has a very good
usability and is platform-independent, a very good
place to start from. :)
Since I have seen others requesting this "layered
LaTeX export feature" on lists and forums, but I did
not see that it was coded, I hereby volunteer to
implement this feature. I hope to get some help from
this list to implement this feature into Inkscape.
I only had a 2 minutes look at the sources, but my
plans are roughly like that:
- descent the document tree, find text items, write
them to a LaTeX file, remove them form the tree
- pass the graphics-only document tree to the standard
PS/PDF export routines
Could it work out that way?
Greetings,
Jan

This could work, but I'd suggest a different way to do it. If I were
trying the same thing, I'd probably write an effect that was "Put Text
nodes on top". Have it so that you can run that effect, and then do what
ever you want with the document (export PDF, export to SVG, etc.)
Probably the easiest way to implement that effect is through scripting,
but the trick is going to be handling the transformations of parent nodes.
So, if the text nodes is in a group that has a transform on it, that
transform needs to be applied when you move the text node out of that
group. I'd probably solve that by just including the same grouping in
your top layer.

Hi,
at this point I have implemented a Python script that
features basic text export into a LaTeX picture
environment. I am also able to remove the text
nodes form the tree for later EPS/PDF export.
To complete my prototype cycle, I would like to know:
- Is there any way that I can trigger the standard
Inkscape export modes (PS/PDF) from within my
script?
- Will I have access to the calculation results of the
bounding box for the current image?
Regards,
Jan

If you're using Inkscape scripting, no, the only interface is STDIN and
STOUT. As the DOM support finishes up in Inkscape we plan on providing
a more feature rich scripting environment where the script will execute
in Inkscape, but that is not currently available. You can do that if
you implement the extension as a C++ extension though.

That's not passed to the script, but you can call another instance of
Inkscape with the command line parameters to calculate the bounding box
of any SVG element. If you do "inkscape --help" you can get a list of
all the command line parameters available.
