1 Scope
This Recommendation | International Standard defines a set of lossless (bit-preserving)
and lossy compression methods for coding continuous-tone, bi-level, grey-scale, colour
digital still images, or multi-component images.
This Recommendation | International Standard:
-
— specifies extended decoding processes for converting compressed image data to reconstructed image data;
-
— specifies an extended codestream syntax containing information for interpreting the compressed image data;
-
— specifies an extended file format;
-
— specifies a container to store image metadata;
-
— defines a standard set of image metadata;
-
— provides guidance on extended encoding processes for converting source image data to compressed image data;
-
— provides guidance on how to implement these processes in practice.
