Unsolved TransparentBlt - fast equivalent for QPixmap
I'm currently searching for an equivalent to TransparentBlt to use with QPixmap. My actual solution uses createMaskFromColor in order to retrieve a mask out of QPixmap. But - as the help already indicates - this function is slow because it involves converting to/from a QImage. Is there an alternative to realize a fast image transfer with a transparent color?
Any help would be appreciated.
Thanks in advance.
