Hello everyone, I have some performance issue when I am using QPixmap.
I am getting image from buffer and I create QImage. After that using QPixmap::fromImage(), creating pixmap and set it to QGraphicPixmapItem to be drawn in scene. When I put the timer to see how much time Qt spending to create QPixmap, I realize that I converting from Qimage to QPixmap taking ~20 times more time than crating Qimage from buffer. By the way, I am getting image approximately every 200 ms some times faster than that. Do you have any suggestion to increase the performance? Can I draw QImage into scene without Qpixmap convertion? How ? Thank you. Celal
