Tell you a simple way:You don't put the picture on the PictureBox, you are not in the background of the PictureBox put an Image control again, and then set the Image to the Image, then change my Stretch Image element attribute to true, so, you just need to move or scale the size and location of the Image element can realize your purpose,
