How to print an image and scale it to fit page?

pmh4514

Hello,
I use the following code to successfully print an image, but it fills the entire 8.5x11 piece of paper and is chopped off on the sides. What must I add so that it scales to fit the page?
Thanks!

QImage img = myPixmap.toImage(); // myPixmap previously exists
QPrinter printer;
QPrintDialog *dlg = new QPrintDialog(&printer,0);
if(dlg->exec() == QDialog::Accepted) {
    QPainter painter(&printer);
    painter.drawImage(QPoint(0,0),img);
    painter.end();
}

Hi,

It's been some time but isn't it something you set in the QPrintDialog ?

That was my first thought too, but apparently not. (unless that's due to my own printer..)

QPainter

You can get paper size from printer and draw image by this function
void QPainter::drawImage ( const QRectF & target, const QImage & image, const QRectF & source, Qt::ImageConversionFlags flags = Qt::AutoColor )

it doesn't seem to matter what rectangle values I pass to drawImage, or if it's based on the paper size or even if I try a dummy rect that is like (0,0,50,50) - the resulting print still occupies the entire 8.5x11 sheet of paper and is cutoff on the right..
