Information technology - Lossy/lossless coding of bi-level images (ISO/IEC 14492:2001, IDT)
This Malaysian Standard 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 standard also defines file formats to enclose the coded bi-level image data.
