I have been thinking about using Inkscape and Inkview as a replacement
for powerpoint (one of the few reasons to reboot to Windows).
I decided to give it a try recently, and it is great in some respects,
and lacking in others. I thought I would describe my process, and some
of the issues I am running into, and see if anyone has any suggestions.
The process:
(1) I create one, or multiple template slides (in Inkscape), that have
placeholders for the title, substitle, and content (although this could
easily be generalized).
(2) I create a text file (called the outline file) which describes the
slides, including titles, content, and the template file to use for each
slide.
(3) I have a python script which uses the template files and the outline
file to create svg files for each slide.
(3a) The title and subtitle are easy - they are just inserted into the
proper placeholder in the template svg.
(3b) The content, which includes equations, is more complicated. It
is run through LaTex, and converted to svg, then inserted into the
template svg. The conversion process is LaTex -> dvips -> pstoedit ->
skconvert, which provides an svg file that I can process to get the text
part, and insert into the template svg.
(4) I can edit each slide svg file in Inkscape to make any changes
necessary.
(5) View slides with Inkview.
My questions:
(a) Is there a better way to do this? I could do everything in LaTex,
but I then I lose the ability to tweak the result, such as moving
pictures around, or changing font sizes, etc., like I have in
powerpoint, or Inkscape.
(b) Is anyone else using Inkscape for presentations? Interested in
using it?
(c) Step 3b is pretty poor right now - I am still working on it, but the
conversion process basically creates a seperate text element for every
letter. I can do some processing to improve on this, but it is very
inelegant. Anyone have a better idea?
(d) Also in step 3b, I am losing some greek letters (but not all) in the
conversion from LaTex to svg. I have not tracked the cause of this down
yet.

Sounds like you've got a good setup. I've not heard of a better way,
although Ted's presentation stuff may be worth looking at. Ted, maybe
you can throw in some comments?
The Xorg/Cairo folks do SVG presentations, although they use a different
tool for it (I asked keithp about this last year, but the tool wasn't as
polished as inkview at the time). Their interesting approach was to
write the presentation in an XML format and use XSLT to transform it
into SVG.

Yes, several of us have used inkview for presentations, although it
sounds like you've gone a step or two beyond us. :-)

I assume you're going LaTeX->PS->SVG? Try viewing the Postscript file
and see if the text is presented there correctly. If so, then that
suggests a PS->SVG transformation issue. Also, by 'losing' do you mean
the text is gone completely or it just doesn't display (look in the SVG
file in a text editor). If the text is there but just not getting
displayed, it could be a font problem.

This sounds like the right way to do it. I wonder if the code they use
to do this is available. There is a real need for powerful presentation
software on gnu/linux.

That was poorly worded by me - I meant that some greek letters get
changed to their non-greek equivalent. For instance, beta is becoming
b. It only happens to some letters though - I don't know why.
The beta is fine in the postscript, and fine in the skencil document, so
it must be a problem with the skconvert program. I will file a bug with
them.
A second issue is that for some reason, the letters fi get converted
into a strange character which stops inkscape from importing, and
inkview from showing. This shows up first when the file is converted to
a skencil document, so I suppose that is another skencil bug.

Sounds like it's doing a "smart" conversion from a nice character to
the
'b' in an ASCII or Latin-1 mode.

Could be the same or similar thing happening. There is an 'fi' ligature
that could be getting confused at some point.
Could you try "hexdum -C" on your file at different points to see which
bytes are being used? Aside from the characters in question, also look
for a few strange ones at the very top.

Well, I don't know that I can add that much. I've really enjoyed using
Inkscape to create my presentations, but I just did everything in
Inkscape, no other software used. I created a template file, and put it
in the templates directory, and just made slides. Then you have full
control of each slide, but template changes suck :)
You might look at Bulia's work with the tutorials, there might be
something to reuse there. He's taking docbook and turning it into both
SVG and HTML using XSLT.
