What is JBIG2?
JBIG2 is an image compression standard specifically designed for bi-level (1 bpp) images, commonly used in scanned documents, fax transmissions, and PDF files. Developed by the Joint Bi-level Image Experts Group, JBIG2 provides superior compression rates compared to other standards like CCITT Fax Group 4. It is capable of compressing black-and-white images 2-5 times more effectively than Group 4, making it an ideal choice for applications that require high-quality image compression, such as PDF creation and editing.
Key Features of the VeryDOC JBIG2 Compression SDK
The VeryDOC JBIG2 Compression SDK is a versatile tool that offers numerous features to meet the needs of developers:
- Efficient Image Compression: The SDK allows developers to compress black-and-white images into JBIG2 format, significantly reducing file size. For instance, a 122 MB uncompressed document can be reduced to just 1.15 MB using JBIG2 lossless compression, or even down to 0.55 MB with lossy compression.
- Versatile Format Support: The SDK supports compression from various image formats, including TIFF, PNG, and BMP, into the JBIG2 format. It also enables the encoding of JBIG2 data streams into single or multipage files and PDF image resources.
- Advanced Encoding Techniques: The SDK uses sophisticated methods such as symbol extraction, classification, text region coding, and refinement coding to achieve high compression rates. It also supports generic region encoding automatically.
- Fast Processing: Developed in C/C++, the SDK is optimized for speed, ensuring that encoding and decoding processes are fast and efficient.
- Compliance with Standards: The JBIG2 codec algorithm in this SDK is fully compliant with the official ISO/IEC 14492 specification, ensuring compatibility and reliability.
- Flexible Integration: The SDK provides an easy-to-use API that allows seamless integration into existing applications, enabling developers to add JBIG2 image rendering capabilities with minimal effort.
SDK Components and Functions
The VeryDOC JBIG2 Compression SDK includes several key components and functions to facilitate its integration:
- jbig2en.h: The header file for the JBIG2 Encode and Decode Library.
- jbig2en.dll: The dynamic link library (DLL) that contains the encoding and decoding functions.
- jbig2en.lib: The library file for linking the SDK with your application.
