It's really easy to rotate the image by an integer multiple of 90. Public   Static Bitmap kirotate90 (Bitmap IMG) ... { Try ... {IMG. rotateflip (rotatefliptype. rotate90flipnone );ReturnIMG;} Catch ... {Return Null;} }

Image processing software must meet the following requirements: how to place an image on another image, such as a company or individual logo on a large image. In fact, the principle is very simple. Suppose we have a 800*600 big image (Bitmap B0),
