The GETIMAGE and PUTIMAGE routines transfer images between memory and the screen and give you options that control the way the image and screen interact. When you hold an image in memory, the application allocates a memory buffer for the image. The IMAGESIZE routines calculate the size of the buffer needed to store a given image.
Routines that end with _W use window coordinates; the other functions use viewport coordinates.
