issues with Technical PDF docs (equations; matrice...)
Despite the fact that "Calibre" is a great tool to convert data for my ebook (Kindle), It fails (like many other tools) to perform proper conversion of scientific PDF documents.
For example, if you take a PDF document from computergraphics world made of equations; matrices etc. : the equations and other complex notations are just screwed-up.
I am not so surprised because it seems like this is a known issue : I never found any decent converted that could do the job properly. Even Amazon Kindle converter (through email) fails...
A naive approach from Calibre would be to read the PDF document; locate the complex notations (equations etc.); convert them to simple pictures and integrate these pictures within the document to replace the unsuccessful conversion...
Another possible workaround : find the PDF tool online that does perform this job of converting complex equations and matrices to simple images; then use the modified PDF document with "Calibre"...
Any clue ? Any advice on which PDF tool to use so I could bake the PDf docs to become "Calibre" friendly ?
PS: Yes, PDF docs are Kindle-compatible... but I prefer other ebook formats so that the kindle can do search; provide the dictionary on words; change the font size etc.

Get the original files and work from them.
There's a reason why math is ``penalty copy''.
Hevea or latex2html will make the small bitmap images which you are wanting (given a TeX source).
Failing that, run the images through a system which will convert them to TeX code such as Infty's equation recognition system or the Freehand Formula Entry System:
