View Full Version : PDF-file rendering with OpenGL?
09-17-2002, 10:05 PM
Is there any possibility to view/render PDF (or other document-types) with OpenGL?
Any libraries for doing this? Functions in OpenGL/GLUT? Other?

Sure you can do it, I am not sure why you would like to do it though ?, I don't know of any code to do it and the OpenGL API is not very useful for that kind of rendering, but have a look at the source for xpdf for example (that's a Linux app for viewing pdf files).

The reason that I want to show PDF-files is that my application is supposed to show documentation of different kind that already exists on PDF-format.
The information could of course be converted to other formats, but I would like to be able to actually download a pdf-file from the Internet, and then display it as a 3D-object (one page at the time, visualized as a paper/book).

By the way! To all of the rest of you folks: Please feel free to let me know if you have other suggestions/code samples to render PDF with OpenGL :-)

I believe .PDF is a proprietary format - but heres an idea - perhaps there is some way you could utilize the acrobat plug-in to render pages of a PDF file to a window or some kind of DC and then generate a DIB for use as a texture in OpenGL.
I feel that actually writing a PDF file renderer would take probably as long if not longer than Adobe actually took to make theirs in the first place http://www.opengl.org/discussion_boards/ubb/wink.gif
Maybe, just maybe it might be worth asking Adobe about this directly via. their support address?
