I actually had occasion to look into this at one time. Do a search in the source code of qimage.cpp for "sanity check for potential overflows" and you can see the checks that Qt is doing. Basically,

• The number of bytes required (width * height * depth_for_format) must be less than INT_MAX.
• It must be able to malloc those bytes at the point you are creating the QImage instance.
