In http://www.mail-archive.com/pyqt@riverbankcomputing.com/msg18113.html Phil Thompson was asking about the non-const QImage constructor:
QImage(uchar *data, int width, int height, int bytesPerLine, Format format); and suggested implementing it using "void *" as the first argument. However, when I look at the online doc for PyQt's Qimage() class at http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qimage.html#QImage-6 I see these two constructors: QImage.__init__ (self, str, int, int, int, Format) QImage.__init__ (self, sip.voidptr, int, int, int, Format) Unlike the similar QImage constructor that takes a non-const data buffer, this version will never alter the contents of the buffer. For example, calling QImage.bits() will return a deep copy of the image, rather than the buffer passed to the constructor. This allows for the efficiency of constructing a QImage from raw data, without the possibility of the raw data being changed. So it appears the sip.voidptr version is the const version? I want to use the non-const version, but don't know how to get a str as the first argument? If I have the address of my image raw data, how do I convert that to a str that QImage.__init__ (self, str, int, int, int, Format) will accept? _______________________________________________ PyQt mailing list PyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
