JBig2Decoder.NETStandard

Converts a JBIG2 (*.jb2) image to a RGB byte array. JBIG2 images offer lossless compression for bi-level (black and white) images. The spec was released in 2000, at the peak of fax machine technology.

There are no package dependencies and it is compiled for:

  1. .NET 8.0
  2. .NET 6.0
  3. .NET Standard 2.0
  4. .NET Framework 4.8

Usage

string file = "pic.jb2";
var input = File.ReadAllBytes(file);
var jbig = new JBIG2StreamDecoder();
int width = 0;
int height = 0;
byte[] output = jbig.DecodeJBIG2(input, out width, out height);
// the resulting 'byte[] output' is a RGB array

// Then the bytes can be converted to an image using your favorite image processing library.
// To convert to a png using ImageSharp:
var image = Image.LoadPixelData<Rgb24>(output, width, height);
image.SaveAsPng("pic.png");

Versions

  • 1.5.0 - .NET 8

  • 1.4.0 - All package dependencies removed and only a byte array is created

  • 1.3.0 - All libraries converted to .NET Standard 2.0

Library that converts JBIG2 (.jb2) files to binary image arrays.  Each pixel is white or black and the compression is 2-4 times smaller than JBIG!

The library has no dependencies and is compiled for .NET6, .NETStandard2.0, and .NET Framework 4.8.

It is based off of JBig2Decoder.NETCore
