  • Apparatus, product, and method of trapping using a distance buffer
    Patent number: 6992798
    Abstract: A method, apparatus, and product to generate trap areas. One embodiment is a method for generating a trap pixel of a trap area surrounding one or more trapping edges of an image that includes, for each trapping edge in the image, and for each pixel within a predefined area around the trapping edge, comparing the distance of the pixel from the trapping edge according to a distance measure with a provided measure indicative of the distance of the pixel from any edge of the image to determine if said each pixel is closer to the trapping edge than to another edge. The method further includes, if said pixel is closer to said edge than to any edge, setting the pixel as a trap pixel of the trap area, including setting a trap color for the trap pixel.
