Abstract
An electronic projection device stores a library of images used for gobos, or light shaping devices, to shape the light. Those gobos each have a specified size. A device adjusts the amount of ligth which passes based on the size information about a gobo. The size of the image is automatically determined, and maximize is used to adjust the amount of opening of a mechanical device, such as a motor driven iris. In this way, the motor driven iris can automatically open to a size that is based on the image information.
