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.
Claims15
A method for manufacturing a security document including a pattern, the method comprising the steps of:
- selecting a bounding region in a document, an image object, and a raster image;
- cutting the image object into image object partitions;
- selecting a task including a sequence of image transformations, a minimum one of the image transformations depending on input parameters of the task;
- duplicating the image object as the pattern in the bounding region;
- and
- determining for each of the image objects in the pattern:
- a position area in the bounding region;
- and
- a set of values from pixels in the raster image within the position area relative to the raster image, and transforming each of the image object partitions by the task with the set of values as an input value of the task;
- wherein
- an image transformation from the sequence of image transformations includes a translation.
