[Qt-interest] Creating jpeg/png image from Qt

[Deepak Chandran]

I have done this using the following:
                QPixmap pixmap(1024,1024);
pixmap.fill(QColor(255,255,255,255));
 QPainter painter(&pixmap);
painter.setRenderHint(QPainter::Antialiasing);

graphicsScene.render(&painter,QRectF(), graphicsScene.itemsBoundingRect());
 pixmap.save(fileName + tr(".PNG"),"PNG");

Hope that helps. I usually save the scene as PDF:

                QPrinter printer(QPrinter::HighResolution);
printer.setOutputFormat(QPrinter::PdfFormat);
printer.setOrientation(QPrinter::Landscape);
printer.setOutputFileName( "file.pdf");

                QPainter painter(printer);
painter.setRenderHint(QPainter::Antialiasing);
graphicsView->render(&painter);
