Not with Qt itself. You can convert a PDF document to a QImage using Poppler-Qt4. Once you have a QImage, you can save that to whatever format QImage supports.

Poppler-Qt4 is just a Qt wrapper for poppler itself, which you will also have to download and build. I think poppler is only available on linux platforms.

hi d_stranz

first of all thanks to you.

i am already trying with Poppler-Qt4, and i have already installed Poppler-Qt4.

But i am not able to convert PDF document in QImage. If it is possible then my work is over.
can you provide me any link for this or demo source for converting pdf to QImage.

Did you actually look at this page? It contains all the code you need to open a PDF document, go to a specific page, then render that page to a QImage using Poppler-Qt4.

If you want to render a multi-page document to a single QImage, then you need to divide your QImage up into page-sized rectangles, set the x, y and call renderToImage() for each page.

Hi, Sanjeet.
I wonder have you ever worked it out? Do I need another 3rd party manual toolkit? When it comes to PDF converting process, I have another question, I wonder have you ever tried to convert pdf to other image files before? As for myself, I am testing the related PDF to PNG converting, PDF to BMP converting , and PDF to JPG converting programs these days. Do you have experience about it? Any suggestion will be appreciated. Thanks in advance.



Best regards,
Peter

All the tools you need are mentioned in this thread already. Once you have a QImage you can save it in a range of formats.
