Abstract:
1. An image processing apparatus for reading print data containing a plurality of objects including image objects each having one or more colors and color objects each having one color, and generating a trap graphic along a neighboring vector, which is a boundary portion between any two overlapping objects from among the plurality of objects, the boundary portion being included in a contour of one of the two overlapping objects that is disposed on top of the other overlapping object, the apparatus comprising: a sample coordinate extraction portion for extracting coordinate points in the vicinity of the neighboring vector as sample coordinate points from among all coordinate points at which the image object is rendered, wherein at least one of the two overlapping objects is an image object; a color value acquisition portion for acquiring color values representing colors at the sample coordinate points; and a trap graphic generation position (TGGP) determination portion for determining a position in which to generate the trap graphic with reference to the neighboring vector, based on the color values at the sample coordinate points acquired by the color value acquisition portion, wherein the color value acquisition portion acquires the color values at the sample coordinate points by rendering a rectangular area in the smallest possible size, the rectangular area containing all the sample coordinate points extracted by the sample coordinate extraction portion.
