A method, system, and program product are provided in which display data for a display area that includes at least one window is mapped to a shared format. Attribute information for each window in the display area is determined and stored in a unique node. A hierarchy of nodes is generated using the attribute information. For each pixel in the display area, the corresponding node is determined. Using the attribute information in the node, the display data is mapped to a shared format. The mapped display data can then be shared with one or more other systems.
