Module filter_impls 

PDF stream filter implementations

This module contains implementations of various PDF stream filters according to ISO 32000-1:2008 Section 7.4

JBIG2 Decoding Infrastructure

The JBIG2 decoder (ITU-T T.88) is implemented across multiple submodules:

• mq_coder - MQ arithmetic entropy coder (Section 7)
• bitstream - Bitstream reader for variable-length codes (Section 6.2)
• huffman - Standard Huffman tables B.1-B.15 (Annex B)
• generic_region - Generic region decoder (Section 6.2)
• symbol_dict - Symbol dictionary decoder (Section 6.5)
• text_region - Text region decoder (Section 6.4)
• page_buffer - Page buffer manager (Section 6.3)
• halftone_region - Halftone/pattern dictionary decoder (Sections 6.6, 6.7)
• jbig2 - Main decoder and segment parsing
