  • Object-based raster trapping
    Patent number: 7359530
    Abstract: Trapping graphics during pre-press workflow involves intensive computation. In this invention, the trapping engine uses simple bounding boxes, colors, and temporal order information, to eliminate the possibility of trapping many pairs of objects without ever having to calculate their exact shapes. By considering the temporal order of the objects in a page, such a z-order display list, the trapping engine can quickly reject the possibility of trapping in areas where it is not necessary.
