VeryUtils JBIG2 Encoding and Decoding SDK Library can be used to encode black and white image data into JBIG2 compressed data, and also decode the JBIG2 compressed data to Windows DIB data, it's a great SDK Library to compress image files to JBIG2 data stream and decompress JBIG2 data to bitmap data. JBIG2 encodes bi-level (1 bpp) images using a number of clever tricks to get better compression than G4. developed in C/C++. JBIG2 is an image compression standard for black-white images. It is suitable for both lossless and lossy compression. JBIG2 compression can compress a black-white image 2-5 times more effectively than CCITT Fax Group 4 compression. Now the JBIG2 compression is very popular in PDF documents: most of scanners generate PDF documents with JBIG2 images, many PDF editors use JBIG2 compression decoder and encoder, all PDF compressors use JBIG2 compression viewer and encoder. homepage With this VeryUtils JBIG2 Encoding and Decoding SDK Library you can: * Compress image files with JBIG2 technology to save the disk space and fast web transfer. * Generate JBIG2 data stream from black and white TIFF, PNG, BMP, etc. formats. * Generic region encoding automatically. * Perform symbol extraction, classification and text region coding. * Perform refinement coding and Compress multipage documents. * Lossless JBIG2 Encoder Windows Dynamic Libary: bases on Jbig2, but easily integrate with your own application. * Developed by C/C++, the processing speed is very fast. * JBIG2 codec algorithm has been developed in full compliance with the official ISO/IEC 14492 specification. * Decode JBIG2 image stored in a single or multipage JBIG2 file and PDF image-resource. * Encode JBIG2 image and save it to a single or multipage JBIG2 file and PDF image-resource. * Use the JBIG2 compression instead of CCITT4 to compress PDF image-resources for decreasing size of PDF document.
