标准摘要
This document 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 document: – 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.
