Hello,
I worked a little on "add slide thumbnails to HTML export" part.
The code compiles ok with Debian testing updated x86 (and no parameter
at all in autogen), gcc (Debian 4.5.2-4)
I only tried this :
- create a impress document with 2 slides
- export to XHTML, HTML and save it in test.html
then I got these files :
- test.html
- img0.png
- img1.png
- thumb0.png
- thumb1.png
- text0.html
- text1.html
I don't know if it's what was expected but i'm sure it needs some
reviewing since I added, changed and removed 1 or 2 things from the
original patch.
If this patch is ok, i can of course push it.
Julien.
