JBIG and JBIG2 Image Compression SDK Libraries

LEADTOOLS compression libraries for .NET (C#, VB, Core, Xamarin, UWP), C, C++, iOS, macOS, Linux, Java, and web developers fully support the JBIG and JBIG2 standards for bitonal, grayscale, and color image data.

Feature-rich JBIG and JBIG2 Image Compression SDK

JBIG and JBIG2 Image Compression Libraries

LEADTOOLS compression libraries can load and save JBIG and JBIG2 compressed bitonal, grayscale, and color image data in JBIG and TIFF file formats. As well, LEADTOOLS supports multi-resolution JBIG to store multiple resolutions of the image without any added storage overhead.

JBIG Functional Blocks

To achieve the highest compression ratios possible, LEADTOOLS takes full advantage of all the functional blocks of the JBIG compression standard:

  • The Adaptive Arithmetic Encoder, which represents the heart of JBIG, predicts and encodes future data symbols based on the data that is currently being encoded.
  • Adaptive Template Block provides improved compression efficiency (up to 80%) for images rendered with half-toning.
  • Typical Prediction Block skips the encoding of regions of solid pixels to improve compression.
  • Resolution Reduction Block generates a lower resolution version of the image data.
  • Deterministic Prediction Block skips the encoding of data that can be determined by the neighboring pixels in a lower resolution version of the data.
Various JBIG2 features

Specialized JBIG2 Features: Sequential and Random-access

LEADTOOLS supports sequential and random-access JBIG2, including the various JBIG2 flavors of text and generic region encoding and decoding procedures based on sequential coding of the image pixels using arithmetic coding. Saving images as JBIG2 results in smaller image file sizes when compared to other industry-standard compressed formats such as JBIG, CCITT G3, and G4. JBIG2 can compress bitonal images 2 to 5 times better than the same image compressed with CCITT G4 compression.

Comparison of Bitonal Compressions

JBIG and JBIG2 offer outstanding compression ratios for all bit depths. However, it is an exceptional choice for 1-bit black and white images, outperforming LZW and TIFF CCITT Group 4.
