Abstract
A method comprises providing image copy and modify commands to a receiver. Each copy command causes pixel values in an area of a display associated with the receiver to be copied to another area of the display and each modify command causes at least one pixel value in an area of the display to be modified. The method further comprises generating a future copy region if a future copy command that is providable to the receiver is encountered. The future copy region defines one or more rectangles of pixels on the display that are copyable in the future on the display associated with the receiver. The method also comprises using the future copy region to avoid sending a future copy command to the receiver that will copy pixel values that are to be modified on a display associated with a sending system.
