I create monochrome images in QImage format :: Format_Mono (1-bit per pixel) . Then I need to combine them in a certain way, for which I create a scene and add them there. How then can I save the resulting scene in the .tiff format so that the quality of the images remains the same already being in this, combined form?

    If you want to copy "pixel to pixel" what the user sees in QGraphicsView , you do:

     QPixmap pixMap = this->ui->graphicsView->grab(); pixMap.save(fileName);

    If you just want to draw a picture from the scene:

     QImage image(fn); QPainter painter(&image); painter.setRenderHint(QPainter::Antialiasing); scene.render(&painter); image.save("file_name.png")

    The second option is preferable, as it allows you to save a scaled scene.

    • I asked about the quality because the images that I form have a dimension of 7100 x 7100 pixels with a pixel size of 0.00635 mm. unless at transfer on a scene this quality will not be lost? - jesuscrew77 6:18 pm
