Abstract
Computer image magnification often results in the loss of the contextual information. Two image magnification prototypes are presented that solve thk problem. In both the base image is shown at all times with lines connecting the magnitled region on the base image to the magn~led image. Both prototypes allow for smooth pan, scroll, and zoom of large 2D images with both coarse and fine translation movements. The second design implements a magnifying glass metaphor whereby the degree of magnification is controlled by the distance of the enlarged image to the magnifkd region of the base image
