JBIG2 Image Conversion and Viewers
VeryPDF Software offers powerful support for JBIG2 — both viewing and saving JBIG2 compression is currently available in our Image2PDF OCR for Windows products, including .NET, JBIG2 viewing is available across all Windows platforms. Using Image2PDF OCR SDKs you now have the ability to build powerful applications for image and document manipulation that include the extremely powerful black and white compression JBIG2 provides. Of special interest is support for JBIG2 within PDF documents, offering you the ability to create highly compressed documents that are easily readable by Adobe Acrobat as well as VeryPDF products.
Document Compression
Our Image2PDF Imaging SDKs allow
you to build viewing and conversion applications that utilize JBIG2 compression,
as well as over 100 other formats and that provide lots of expert imaging
functions. JBIG2 compression works especially well with PDF documents, allowing
compression without sacrificing image quality, and scanned documents or faxes.
Image2PDF OCR Product, our batch conversion application, provides you the
capability to perform rapid batch conversion right from your desktop or server.
The easy-to-use interface will enable you to quickly compress your files using
JBIG2.
What is JBIG2?
JBIG2 is a highly-compressed black
and white image format that uses symbol recognition and substitution for very
dramatic compression results. Any black and white image can be compressed using
JBIG2 including images stored as Group 4, Group 3, MO:DCA, TIFF, PDF and others.
The JBIG2 compression algorithm works by searching for groups of pixels that are
arranged in similar shapes and using them to define a symbol. Rather than
retaining information on the placement of each pixel, a table is created for
common symbols. This allows users to see incredible reductions in file sizes.
Compression rates of up to 100:1 compared to uncompressed black and white TIFFs
are possible.
JBIG2 is a format for bi-level (black/white) image compression that offers significant advantages over other compression formats:
large increases in compression performance (typically 3-5 times smaller than Group 4/MMR, 2-4 times smaller than JBIG1)
special compression methods for text, halftones, and other binary image content
lossy and lossless compression
multi-page document compression
flexible format, designed for easy embedding in other image file formats, such as TIFF
high-performance decompression: using some coding modes, images can be decompressed at over 250 million pixels/second in software
Note: JBIG2 read/write functionality is an added cost option for all of VeryPDF’s products.
