I have a Qt application written in C++ where I need to render a very large raw image in a 32-bit format within a QGraphicsView. The challenge is that QGraphicsView can only handle 8-bit images, so I need to convert each pixel value to 8-bit. Given the large size of the image (e.g., 9000×3000 pixels), this conversion process is very slow, taking several seconds to display the image completely.
