Abstract
Signature image information is converted from scanner input data into lines of character spaces which can conveniently be presented on a matrix printer. Both the method of image conversion from input scans to output lines of characters and apparatus for interpreting control information accompanying character picture element information are disclosed. An efficient format for presenting the control information and reducing the amount of picture element data stored and handled is also disclosed.
Claims3
A matrix printer for presenting an image of a signature, the improvement comprising:
- means for receiving and storing a count indicative of the number of lines of character spaces having a portion of said image and a count of the number of character spaces in said lines;
- means for contiguously receiving and storing a plurality of blank space indicator bits including a binary bit for each character space of a line of character spaces having a portion of said image;
- logic means responsive to said stored counts for examining each blank space indicator bit in sequence;
- stepping means controlled by said logic means to cause the print head of said printer to skip each character space position having a logical zero corresponding blank space indicator bit;
- data gates controlled by said logic means for gating slice data bytes to said print head at each character space having a logical one corresponding blank space indicator bit, said stepping means stepping said print head between each of said slice data bytes.
