Abstract
A graphics system readily activates and deactivates layers of a multi-layer source image. Image data, such as a multi-layered integrated circuit ('IC') design, is generated for a multi-layer source image. A pyramid of image tiles defines 'on' and “off” states for elements that represent the source image. A bit plane identifies values for the elements for each layer of the source image. Mask image data is generated to zero image data associated with at least one layer of the bit plane. The graphics system generates pixel data from the mask image data, and renders the pixel data on an output display.
