Converting a pdf to jpg images using in Qt

Question

the heading says it all actually:

i want to convert a pdf file into several jpg images. This is to be a part of a software coded in c++ (I'm using Qt for my interface if that matters... :)

Preferably i want the images output to be 72 dpi.

Is there a easy way to do this?

Please comment if you need any more information form me, I'm grateful for any help, tips or answer!

Answer 1

Take pdf2image utility, and run it from you program, collecting its output files.

If you really need single executable (why?) — take a look at its source, and rip everything from it.

Answer 2

You should try to use poppler (or xpdf). You'll have full control of the rendering resolution and can take advantage of image output devices (ImageOutputDev) which will render pages to a framebuffer.Saving this framebuffer to jpeg with libjpeg is ,then , pretty straightforward.
