I need to convert pdf to jpg and bmp for some purpose and I want to do it in assembly (or C/C++/ java). Obviously I will have to use some pdf pasing library/SDK. So do you guys know of any good one ?

Or any other method of parsing pdf file without using any library ?

Managed to double-post due to the board not responding, see post below

Your best bet is probably ghostscript, comes with a binary and a library.

Not 100% sure if the windows one comes with a library, but it should (not checked)

Theres also an open source PDF reader called sumatra, which is open-source, and uses an external parser i believe (cant remember the name, but it should mention it in the manual somewhere).

You could also not use an external library, but that means implementing a PDF parser, so you'll have to find the pdf specification and just implement a library to "render" a pdf into an image.

Theres also already programs which will do this kind of thing for you (pdf -> image), one of which is ImageMagick (pretty sure theres a windows port, although i use it under linux), and theres probably several other implementations for the same thing.

Good luck
