Abstract: A method for manufacturing a security document including a security pattern generation method includes the steps of selecting a bounding region, an image object, and a raster image or a function; cutting the image object into image object partitions; and repeating the image object as a pattern, preferably a lattice pattern, in the bounding region wherein each of the image object partitions of an image object is transformed depending on the position area of the image object in the lattice pattern and the rank of the image object partition.

Abstract: A security pattern generation method includes generating a plurality of draw instructions to define a plane filling line pattern, wherein the plane filling line pattern includes a repeating sub-pattern that defines a line by a sequence of draw instructions, and searching the sequence of draw instructions in the plurality of draw instructions and, if found, overlaying the searched sequence of draw instructions by a graphic object that is scaled to fit and scaled between the two distinct end points of the line.
