[Solved]QPixmap being clipped after rotation

  • @

    QImage img("lena.jpg");

    rotate_image_implace(img, angle); //rotate the img with angle degrees


    type of graph_pixmap_ is QGraphicsPixmapItem
    type of graph_scene_ is QGraphicsScene

    This may clip the image if their height and width are different, how could
    I rotate the image without clipping it?

    Because the program need to save the image after rotating and mirror(vertical and horizontal),
    rotation of QGraphicsPixmapItem is not adopted.

  • After struggling of several hours, I find out that my scaling methods has some bugs, sorry to
    bother you all.
