      Use case:

      QImage is rendered with QImage::Format_Mono

      The image is printed using QPrinter into pdf format.

      The resultant file size is around 35Mb and the time taken is about 9 or 10 seconds.

      When compared with Qt 4.5, the file size is around 300Kb and the time taken is less than one second
