JBIG Format (JBG)

JBIG (JBG) is an industry standard lossless compressed file format for bi-tonal (black and white), grayscale and color images. LEADs JBIG support is comprehensive and handles the various flavors and bits per pixel as defined by the specification including progressive, where you can store and send multiple representations of images at different resolutions without any extra storage overhead. In order to achieve highest compression ratios available by the JBIG format, LEAD also takes full advantage of all the functional blocks of this robust standard including the Adaptive Arithmetic Encoder, the Adaptive Template Block, the Typical Prediction Block, the Resolution Reduction Block, and the Deterministic Prediction Block. Saving images in a JBIG format results in smaller image files sizes when compared to other industry standard compressed formats such as CCITT G3 or G4.

The file constants associated with this file format are:

Constant Read Support Write Support Description
FILE_JBIG 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32 BPP 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32 BPP [115] JBIG.
FILE_TIF_JBIG 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32 BPP 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32 BPP [139] TIFF with JBIG compression.
