Hello. I checked out the reference manual as you had suggested. But the interpolation functions of floating point module yet need to be developed i.e the API of that module provides no info about the interpolation functions.
Hardy Falk wrote the interpolation code in November 2007. In that time we didnt have a detailed design of the library and thus he nicely wrote a full implementation of the PDF functions. Now, with the new design, we will split the functionality of the PDF functions in two parts: the interpolation routines in the base layer and the PDF functions in the document layer. Lets see if Hardy want to integrate his interpolation routines himself. That would be the ideal situation. I have also checked and downloaded the source of the floating point module. I still don't have an account with gnupdf.org(I had mailed the pdf-maintainer). As soon as you start working I will open accounts in gnudpf.org and gnupdf.org/flyspray for you. I checked orkut and other social networking sites. I found no Gnupdf community there.I think if we open up gnupdf communities there we may create interest in potential developers. That could be interesting. I am not a user of that kind of social networks at the moment.
