File Formats: LEAD 1 Bit Format (CMP)

LEAD 1BIT is a set of proprietary 1-bit LEAD compressed formats that have better compression and performance than JBIG, JBIG2 and CCITT G4, but not as good as the newer LEAD Advanced Bitonal Compression (ABC) format. Type B provides better compression ratios than Type A.

File constants associated with these file formats are:

Constant	Read Support	Write Support	Description
Lead1BitA	1 BPP	1 BPP	LEAD Proprietary 1-bit Compression Format, type A. (optional, legacy use only)
Lead1Bit	1 BPP	1 BPP	LEAD Proprietary 1-bit Compression Format, type B.
