I could get myself started with image-exporting to pdf (all courtesy you :) ) One thing I must tell you; right now, I just got myself bootstrapped, without truly putting the correct values in "target" and "source". I have two queries though :: a) "target" represents the target-canvas, of which the image will take the size, right? b) If yes, then I find it a little odd, that no such target is specified, while exporting a text-document to pdf. For example, here is my code to export a text-document to pdf :: #################################################################################### from PyQt4.QtGui import * import sys app = QApplication(sys.argv) text_file_path = open('sample.py').read() doc = QTextDocument(text_file_path) printer = QPrinter(QPrinter.HighResolution) printer.setOutputFormat(QPrinter.PdfFormat) printer.setOutputFileName('sample.pdf') doc.print_(printer) #################################################################################### Here, we can see that no "target" QtCore.QRectf is passed to the printing options. Any idea of this descrepancy? (as to why the "target" canvas is specified while exporting an image; but not when exporting a text-document, though the "target" canvas size is usually fixed, irrespective of the source mime-type).
