Hello Preetam.
I would like to help with the development of the gnu pdf project, but I am not really sure how I should start contributing, so any suggestions would be welcome. Many thanks for your interest in collaborating in the development. I have also mailed [EMAIL PROTECTED] for account with gnupdf.org but have not recieved no reply since. Sorry about that. I have been travelling these days and had not an opportunity to answer your email. I have studied the stuff in gnupdf.org . I would like to help with the foating point module developement(matrices and interpolation). Nice. There is a primary version of the desired API of that module in the Library Reference Manual. Did you take a look to it? You can find the reference manual both in the webpage (http://www.gnupdf.org/Lib:Reference_Manual) and in the doc/gnupdf.texi file in the sources tree.
