EINFÜGUNG VON TRAPS IN SEITEN IM SEITENBESCHREIBUNGSSPRACHFORMAT |
摘要 |
<p>A trapping technique which accepts a Postscript or other page description language (PDL) file and outputs a file in PDL format having the correct traps. The input page is first divided into sub-portions, or tiles, and the tiles are individually processed by evaluating the input file in a corresponding clipping window. Each tile is then analyzed to determine where edges exist. The edge data is fed to an edge converter which produces a list of color transitions consisting of the analytic description of each edge and the color information along the sides of the edge. The color transition information is fed to a trapping analyzer which generates trap vectors in accordance with a set of desired trapping rules. The trap vectors are then converted to PDL form. As a final step, the trap vectors are added to the original PDL file. The final trapped page may be printed on standard typesetters without the need for special trap generator hardware.</p> |
