OCR A Wikipedia. OCR A is a font that arose in the early days of computer optical character recognition when there was a need for a font that could be recognized not only by the computers of that day, but also by humans. OCR A uses simple, thick strokes to form recognizable characters. The font is monospaced fixed width, with the printer required to place glyphs 6. StandardizationeditThe OCR A font was standardized by the American National Standards Institute ANSI as ANSI X3. X3. 4 has since become the INCITS and the OCR A standard is now called ISO 1. There is also a German standard for OCR A called DIN 6. ImplementationseditIn 1. American Type Founders produced OCR A, one of the first optical character recognition typefaces to meet the criteria set by the U. S. Bureau of Standards. The design is simple so that it can be easily read by a machine, but it is more difficult for the human eye to read. As metal type gave way to computer based typesetting, Tor Lillqvist used Meta. Font to describe the OCR A font. That definition was subsequently improved by Richard B. Wales. Their work is available from CTAN. To make the free version of the font more accessible to users of Microsoft Windows, John Sauter converted the Meta. Font definitions to True. Type using potrace and Font. Forge in 2. 00. 4. In 2. Grkan Sengn created a Debian package from this implementation. In 2. Luc Devroye corrected the vertical positioning in John Sauters implementation, and fixed the name of lower case z. Independently, Matthew Skala1. Metafont definitions to True. Type format in 2. In 2. 01. 1 he released a new version created by rewriting the Metafont definitions to work with METATYPE1, generating outlines directly without an intermediate tracing step. On September 2. 7, 2. In addition to these free implementations of OCR A, there are also implementations sold by several vendors. Although optical character recognition technology has advanced to the point where such simple fonts are no longer necessary, the OCR A font has remained in use. Its usage remains widespread in the encoding of cheques around the world. Some lockbox companies still insist that the account number and amount owed on a bill return form be printed in OCR A.

Notably, it is used for the subtitles in the show Blacklist. Code pointseditA font is a set of character shapes, or glyphs. For a computer to use a font, each glyph must be assigned a code point in a character set. When OCR A was being standardized the usual character coding was the American Standard Code for Information Interchange or ASCII. Not all of the glyphs of OCR A fit into ASCII, and for five of the characters there were alternate glyphs, which might have suggested the need for a second font. However, for convenience and efficiency all of the glyphs were expected to be accessible in a single font using ASCII coding, with the additional characters placed at coding points that would otherwise have been unused. The modern descendant of ASCII is Unicode, also known as ISO 1. Unicode contains ASCII and has special provisions for OCR characters, so some implementations of OCR A have looked to Unicode for guidance on character code assignments. Dedicated OCR A characterseditThe following characters have been defined for control purposes and are now in the Optical Character Recognition Unicode range 2. F 1. 4Space, digits, and unaccented lettersedit. OCR A unaccented capital letters. OCR A unaccented small letters. All implementations of OCR A use U0. U0. 03. 0 through U0. U0. 04. 1 through U0. A for the unaccented upper case letters, and U0.

Regular characterseditIn addition to the digits and unaccented letters, many of the characters of OCR A have obvious code points in ASCII. Of those that do not, most, including all of OCR As accented letters, have obvious code points in Unicode. Remaining characterseditLinotype1. ImageReader.jpg' alt='Code Ocr Open Software Sources' title='Code Ocr Open Software Sources' />OCR A as follows Additional characterseditThe fonts that descend from the work of Tor Lillqvist and Richard B. Wales define four characters not in OCR A to fill out the ASCII character set. These shapes use the same style as the OCR A character shapes. They are Linotype also defines additional characters.
