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.

General Questions for VeryDOC DOC to Any Converter Command Line Software
Customer Questions and Answers

Customer:

Hi Support,

Refer to my manager Tang's request earlier; we have some questions to clarify by referring to the suggested version below.

https://www.verydoc.com/doc-to-any.html

You can buy the "DOC to Any Converter Command Line Developer License USD$1495" from the above web page.

  1. Notice that from the website sample code, all samples require calling the command doc2any.exe for PDF conversion. Is there any API DLL for us to integrate with? The client's server may block calling the .exe from antivirus software.
  2. For the command that converts without using Office -nooffice, we found that the output alignment was incorrect compared to the conversion with Office. Is there any way to adjust the alignment when using the -nooffice command?
  3. We tested both commands. With the -useoffice command, the conversion to PDF retains the exact layout. We noticed that with every conversion, Word opens and closes, causing an increase in memory usage during the process. Will this impact the server's performance if multiple users execute the command concurrently?
  4. Is it required to install Word on the target server if using the -useoffice command?
  5. Are there any other methods to convert .rtf to .pdf through a web application that ensure proper alignment without using Office?
  6. A concern with using Office is that a Word dialog prompt might appear when opening the RTF file, which can cause high CPU usage and make the server unresponsive.

Hope to hear from you soon. Thanks.

Regards,

VeryDOC Support:

Dear Customer,

Thank you for your message. Please find our answers to your questions below:

  1. API DLL Integration
  2. Output Alignment with -nooffice Command
    • The -nooffice option uses our own technologies to parse and render Office formats. The result will not be the same as the conversion with Office. For the best conversion results, we recommend using MS Office instead of OpenOffice and the -nooffice options.
  3. Server Performance with -useoffice Command
    • Did you use the -showofficeui option to show the Office UI during conversion? If so, try removing this option.
    • Example command line without showing Office UI: 
      doc2any.exe -useoffice 1 "C:\in.doc" "C:\out.pdf"
doc2any.exe -useoffice 1 -useprinter "C:\in.doc" "C:\out.pdf"
  4. Installation of Word on Target Server
    • Yes, if you want to use the -useoffice option, you will need to install MS Office on your server, including Microsoft Word, Excel, PowerPoint, etc.
    • Similarly, if you want to use the -useopenoffice option, you will need to install OpenOffice on your server.
  5. RTF to PDF Conversion Without Office
    • To convert RTF files to PDF without relying on MS Office or OpenOffice, you can use the -nooffice option. This will use our technology to parse the RTF format and convert it to PDF without needing MS Office or OpenOffice installed. However, the result may not be identical to the conversion done by MS Office.
    • Alternatively, you can use OpenOffice instead of the -nooffice option; this might be another option for you.
  6. Word Dialog Prompt Concern
    • Please let us know which Word dialog prompt you encountered. Once we have detailed information from you, we will work on hiding that Word dialog prompt in the doc2any.exe application.

Best Regards,
VeryDOC Support
