CSA ISO/IEC 12088-4:00 (R2019)

CSA Preface 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 Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTCI) for the Standards Council of Canada (SCC), the IS0 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 International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication, For a listing, refer to the CSA Information Products catalogue or CSA lnfo Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by these Committees and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope ISO/IEC 12087 consists of the three parts which define the functional aspects of this part of ISO/IEC 12088. The Common Architecture for Imaging (IPI-CAI) defines the overall architecture. The Programmer's Imaging Kernel System (IPI-PIKS) and the Image Interchange Facility (IPI-IIF) each specify a language independent, image processing Application Program Interface (API) within the Image Processing and Interchange Standard. Either API may be implemented independently or both may be combined in one implementation. For integration into a programming language, IPI-PIKS and IPI-IIF APIs are embedded in a language dependent layer obeying the particular conventions of that language. This part of ISO/IEC 12088 specifies such a language dependent layer for the C language.
