2 questions on QPrint + QImage + PDF

[jiveaxe]

Hi,
these are my 2 question?

1)
I have added "print to pdf" to my program; here the function:

void MainWindow::printToPdf()
{
	QPrinter printer;
	printer.setOrientation(QPrinter::Portrait);
	printer.setOutputFileName("test.pdf");
	printer.setOutputFormat(QPrinter::PdfFormat);
 
	QImage image(700,1000,QImage::Format_ARGB32);
 
	QPainter painter;
	painter.setRenderHint(QPainter::Antialiasing, true);
	painter.begin(&image);
	// Draw some text to image
	painter.end();
 
	QPainter p;
	p.begin(&printer);
	p.drawImage(0, 0, image);
	p.end();
}

void MainWindow::printToPdf()
{
	QPrinter printer;
	printer.setOrientation(QPrinter::Portrait);
	printer.setOutputFileName("test.pdf");
	printer.setOutputFormat(QPrinter::PdfFormat);

	QImage image(700,1000,QImage::Format_ARGB32);
	
	QPainter painter;
	painter.setRenderHint(QPainter::Antialiasing, true);
	painter.begin(&image);
	// Draw some text to image
	painter.end();

	QPainter p;
	p.begin(&printer);
	p.drawImage(0, 0, image);
	p.end();
}

To copy to clipboard, switch view to plain text mode 

When I click the first time on the print button the pdf is created in the right way, but if I click a second time the resulting pdf shows some ugly effects: or the contents of the two print actions overlaps or are present some black dots and lines (apart from the desired text).

I have also added delete &painter, delete &printer, delete &image at the end of the above code but I got segmentation fault calling the print function.

2)
If I have two qimage is it possible print a pdf with two pages, one for each qimage?

Thanks
