VintaSoft JBIG2 .NET Plug-in - Overview

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.

VintaSoft JBIG2 .NET Plug-in is the add-on for VintaSoft Imaging .NET SDK, which allows to decode and encode JBIG2 images using Microsoft .NET Framework.

General Features

  • The plug-in is a pure .NET library written in C#
  • AnyCPU, x86 and x64 mode support
  • 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
    • Decode JBIG2 image to a black-white image
    • Decode JBIG2 image with progress indication
  • Encode JBIG2 image and save it to a single- or multipage JBIG2 file and PDF image-resource
    • Encode 1-bpp (black-white) image to a JBIG2 image
    • Encode image with progress indication
    • Encode image using lossless or lossy JPEG2000 compression
    • Specify the desired inaccuracy (0-100) for lossy compression
    • Use the symbol dictionary for optimal encoding of several JBIG2 images and saving them to a multipage JBIG2 file or PDF document
  • Use the JBIG2 compression instead of CCITT4 to compress PDF image-resources for decreasing size of PDF document - VintaSoft PDF .NET Plug-in is necessary
  • Manage (add, insert, remove) pages of multipage JBIG2 file
