Abstract
Data defining several different information-carrying patterns can be stored on mass storage of a computer workstation and serve as a library of design elements for future designs. The same user-interface techniques that are employed to pick colors in image-editing software (e.g. Adobe Photoshop) and fill textures in presentation programs (e.g. Microsoft PowerPoint) can similarly be used to present a palette of information patterns to a security document designer. Clicking on a visual representation of the desired pattern makes the pattern available for inclusion in a security document being designed (e.g. filling a desired area). A great variety of other features and arrangements are also detailed.
Claims20
A method comprising:
- defining, by a processor, a reference calibration tile, wherein the reference calibration tile comprises a grid of cells;
- assigning, by the processor, a grey-scale value to each cell in the grid of cells;
- drawing, by the processor, at least one line on the reference calibration tile, each line of the at least one line connecting a first point and a second point along an edge of the reference calibration tile, wherein each line of the at least one line passes through a subset of the cells;
- generating, by the processor, a calibration pattern, wherein the calibration pattern is based on the at least one line drawn on the reference calibration tile;
- storing, by the processor, the calibration pattern, wherein the stored calibration pattern can be presented on a graphical user interface associated with a graphics editing program;
- receiving, by the processor, a selection of the calibration pattern;
- and
- adding, by the processor, the calibration pattern, based upon the selection, to a graphical work.
A system comprising:
- one or more hardware processors configured to:
- define a reference calibration tile, wherein the reference calibration tile comprises a grid of cells;
- assign a grey-scale value to each cell in the grid of cells;
- draw at least one line, each line of the at least one line connecting a first point and a second point along an edge of the reference calibration tile, wherein each line of the at least one line passes through a subset of the cells;
- generate a calibration pattern, the calibration pattern, wherein the calibration pattern is based on the at least one line drawn on the reference calibration tile;
- store the calibration pattern, wherein the stored calibration pattern can be presented on a graphical user interface associated with a graphics editing program;
- receive a selection of the calibration pattern;
- and
- add the calibration pattern, based upon the selection, to a graphical work.
A non-transitory computer-readable storage medium having instructions stored thereon, the instructions comprising:
- instructions to define a reference calibration tile, wherein the reference calibration tile comprises a grid of cells;
- instructions to assign a grey-scale value to each cell in the grid of cells;
- instructions to draw at least one line, each line of the at least one line connecting a first point and a second point along an edge of the reference calibration tile, wherein each line of the at least one line passes through a subset of the cells;
- instructions to generate a calibration pattern, wherein the calibration pattern is based on the at least one line drawn on the reference calibration tile;
- instructions to store the calibration pattern, wherein the stored calibration pattern can be presented on a graphical user interface associated with a graphics editing program;
- instructions to receive a selection of the calibration pattern;
- and
- instructions to add the calibration pattern based upon the selection, to a graphical work.
