Information technology - Coding of audio-visual objects - Part 22: Open font format (Adopted ISO/IEC 14496-22:2019, fourth edition, 2019-01)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This Standard supersedes CAN/CSA-ISO/IEC 14492:04 (adopted ISO/IEC 14492:2001). At the time of publication, ISO/IEC 14492:2019 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This Recommendation | International Standard1 defines methods for coding bi-level images and sets of images (documents consisting of multiple pages). It is particularly suitable for bi-level images consisting of text and dithered (halftone) data.
The methods defined permit lossless (bit-preserving) coding, lossy coding, and progressive coding. In progressive coding, the first image is lossy; subsequent images may be lossy or lossless.
This Recommendation | International Standard also defines file formats to enclose the coded bi-level image data.
