System and method for providing high performance image magnification in a web browser

摘要

High resolution details of an image can be accessed through manipulation of a cursor (or data points) on a reduced resolution display. The coordinates of the cursor on the reduced resolution image reference coordinates of a stored high resolution image. As the cursor moves about the reduced resolution image a portion of the high resolution image can be constantly displayed. The portion displayed depends upon cursor coordinates. The portion displayed may also be zoomed in or out.
