How can I convert a GraphicsItem into a pdf, png, or image for printing?

[ayanda83]

Hi guys, I am designing an application for making pamphlets and brochures. I have used the QGraphicsItem to represent the pamphlet pages and now I am facing a problem of how do I convert the QGraphicsItem into a pdf or png for printing.

Thanking you in advance.

Have you tried QGraphicsScene::render()?

Hi, ayanda83.
As for me, I have seldom tried to convert a GraphicsItem into a pdf, png, or image for printing. 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 (http://www.pqscan.com/pdf-to-image/) before? As for myself, I am testing the related PDF to PNG converting (http://www.pqscan.com/convert-pdf/to-png-csharp.html), 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,
Lee

As anda_skoa pointed out, you render the scene to a paint device. That device can be a physical printer, QImage or PDFfile.

Conversion of PDF files into a series of page images (or the like) has nothing directly to do with Qt. Ghostscript and Imagemagick both have conversion abilities along those lines.
