Very interesting, and congrats, Vinayak. As a person interested in both PDF generation [1] and PDF text extraction [2], I'm interested to know what issues you faced w.r.t. accuracy of text extraction and also formatting.
[1] I'm the creator of xtopdf, a Python toolkit for PDF generation from other file formats; http://slides.com/vasudevram/xtopdf http://bitbucket.org/vasudevram/xtopdf [2] I worked on a project to extract text from PDF files. It was done using a C library (xpdf), though, not a Python one. However, the text extraction accuracy issues (some of which are technical issues inherent in the PDF format, according to the vendor of xpdf, Glyph and Cog) are language-independent. There were things like characters getting transposed, missing characters, junk characters sometimes, etc. (I also wrote a heuristics program to detect some such issues, but that too could only reject the bad extracts, not make them correct.) So the extraction was not 100% accurate, at least in my project. Also, like I said, that vendor said the issues are inherent in PDF, partly related to it being a canvas-based model, not a text-based one. I'll try to check out your project some time later.
