摘要： A method and apparatus for overloading operators in Page Description Language (PDL) defined graphics adjusts widths of lines in a manner that yields preferred line widths, such as to compensate for certain undesirable line growth characteristics of a target printer or display device. Line width can be controlled based on various attributes, such as color, size, width, pattern or orientation. Line width can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines a modification attribute to achieve the compensation.

Line width can be controlled based on various attributes, such as color, size, width, pattern or orientation. Line width can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. Also, the method and apparatus can compensate for fill in of reverse-line and “cookie-cutter” holes. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines an operator to achieve the compensation. The compensation can include addition of wider reverse (white) lines under colored lines to prevent the fill in.

摘要： A method and apparatus for overloading operators in Page Description Language (PDL) defined graphics redefines the graphic, such as to compensate for certain undesirable line growth characteristics of a target printer or display device. Line width can be controlled based on various attributes, such as color, size, or width. Additionally, the method and apparatus determine whether a line of an object of the graphic intersects with or completely overlays another object. If it does, only those overlying portions are redefined. A line of the graphic can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. Also, the method and apparatus can compensate for fill in of reverse-line and “cookie-cutter” holes. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines an operator to achieve the compensation. The method also determines whether the line intersects with or completely overlays another object of the graphic.
