Question

I have an image in a picture box, and when I do this in my code:

    pictureBox1.Image.RotateFlip(RotateFlipType.Rotate180FlipX);

The image has a black box on the right side of the picture box?

Answer 1

Hard to repro. For one, the PictureBox control has no idea that the image was changed, it won’t even repaint it. At least do it like this so it knows:

        var img = pictureBox1.Image;
        img.RotateFlip(RotateFlipType.Rotate180FlipX);
        pictureBox1.Image = img;
