[Qt-interest] Drawing to QImage

[Denis Akhmetzyanov]

Hi,
C++ GUI Programming with Qt 4 (2nd Edition) - The official C++/Qt book
*
http://qt.nokia.com/developer/books/cpp-gui-programming-with-qt-4-2nd-edition
 *
*
*
has some useful information about this question. Part  II, Chapter 8, 2D
Graphics, topic "High-Quality Rendering with QImage".
In my experience, the main advantage of drawing on the QImage is that
rendering result looking exactly the same on all platforms. But performance
is worse than direct drawing on a QWidget.
