  • Here, h and w are the height and width dimensions of the image to be processed. If h and w appear in our equation it is to center the mark in the center of the image. Indeed, in an image, the mark’s origin is at the top-left corner of the image (the coordinates (0, 0)). This may be an image that was originally loaded by the Image I/O class from an external image format and perhaps modified using the Java 2D APIs, or it may be one that was created by Java 2D. The Image I/O class provides a simple way to save images in a variety of image formats in the following example:
