Hi,

You would need to use a library like poppler to read the PDF. You can only print to pdf with Qt

Pure Qt code without any external lib ? Not that I know of. However poppler has support for both Qt 4 and 5 so it might help

Hello blu-sky..

I have an idea ...if you can render pdf on QWidget one by one, then in order to convert this pdf you can create a snapshot of QWidget using pixmap.grabWidget();
and save it to jpg format using pixmap.save() function..

Hope it'll help you..

well, that was the question.
If you can render a PDF to a QPaintDevice (like QWidget and QPixmap is anyway) why shouldn't you render it directly to a pixmap...
