Me. PictureBox2. Image. RotateFlip (RotateFlipType. Rotate90FlipNone)
Me. PictureBox3. Image. RotateFlip (RotateFlipType. Rotate180FlipNone)

Want to PictureBox1 image rotation angles respectively PictureBox2, PictureBox3 images, results PictureBox1 PictureBox2, PictureBox3 images have become the last parameter of the picture (that is, the picture of the rotated 180 degrees), please answer prawn!
