![]() In 2011 he released a new version created by rewriting the Metafont definitions to work with METATYPE1, generating outlines directly without an intermediate tracing step. Independently, Matthew Skala used mftrace to convert the Metafont definitions to TrueType format in 2006. Luc Devroye corrected the vertical positioning in John Sauter's implementation, and fixed the name of lower case z. In 2007, Gürkan Sengün created a Debian package from this implementation. To make the free version of the font more accessible to users of Microsoft Windows, John Sauter converted the Metafont definitions to TrueType using potrace and FontForge in 2004. That definition was subsequently improved by Richard B. Īs metal type gave way to computer-based typesetting, Tor Lillqvist used Metafont to describe the OCR-A font. 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. ![]() In 1968, American Type Founders produced OCR-A, one of the first optical character recognition typefaces to meet the criteria set by the U.S. X3.4 has since become the INCITS and the OCR-A standard is now called ISO 1073-1:1976. The OCR-A font was standardized by the American National Standards Institute (ANSI)Īs ANSI X3.17-1981. The font is monospaced (fixed-width), with the printer required to place glyphs 0.254 cm ( 0.10 inch) apart, and the reader required to accept any spacing between 0.2286 cm ( 0.09 inch) and 0.4572 cm ( 0.18 inch). OCR-A uses simple, thick strokes to form recognizable characters. OCR-A is a font created in 1968, 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.
