In the Digia docs (http://doc.qt.digia.com/qt/qimage.html) QImage is said to have both a .bits() method and a .constBits() one, the latter differing in that it does not perform a "deep" copy of the image data. This might be useful if one wants to sample or process the contents of large images.
Similarly there is supposed to be a .constScanLine to match the .scanLine() member (although it is not clear whether a call to .scanLine() would cause a copy of just the one line, or if it initiates a copy of the whole image -- one hopes not!). In the PyQt4 doc (http://riverbankcomputing.co.uk/static/Docs/PyQt4/html/qimage.html) there are "see also" references to constBits and constScanLine, but no other mentions. Attempting to call them gets an Attribute error, so they really aren't defined. Should they be? This is PyQt4.9.5 just installed on Mac OS. Using the Snow Leopard python 2.6 if it matters.
