Every recolour ended with QPixmap::fromImage(), which allocates a second full-size buffer and converts the whole image into the screen format. That conversion was the largest single cost left in the colouring path. Replace QGraphicsPixmapItem with a small item that paints qimg_buffer_ with QPainter::drawImage. The buffer is already what the raster engine wants, so nothing is converted or copied. The item declares its opaque area, as the pixmap item did, so the view still skips the background fill underneath it, and it turns SmoothPixmapTransform off before drawing to keep the nearest-neighbour sampling QGraphicsPixmapItem gave us by default -- zoomed-in detector pixels stay sharp squares. GeneratePixmap is renamed RenderImage: it no longer makes a pixmap. 18.1 Mpx recolour: 22 -> 5.6 ms (28.0 ms before this series). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
