Minimalistic example:

#----------------------------------------------------------------------
image = QtGui.QImage("myImage.jpg")
printer = QtGui.QPrinter()
printer.setResolution(300)
printer.setOutputFormat(QtGui.QPrinter.PdfFormat)
printer.setOutputFileName("myImage.pdf")

painter = QtGui.QPainter()
painter.begin(printer)
painter.drawImage(target, image, source)
painter.end()

#------------------------------------------------------------------------

where target & source are QtCore.QRectF(sheet) & QtCore.QRectF(image)
