ABC (ABC)

LEADTOOLS ABC (Advanced Bitonal Compression), a proprietary 1-bit compression format developed by LEAD Technologies, is a major breakthrough in document capture technology. This set of advanced compression algorithms out-performs all industry standard compression types, and is the best 1-bit lossless compression provided by LEAD.  With LEADTOOLS ABC, customers will be able to realize file sizes 4 to 5 times smaller than the files sizes generated by standard 1-bit compression types such as CCITT Group 4.  LEADTOOLS ABC was specifically designed to allow efficient network transmission of scanned manuals, books, check images and other document types.  This superior compression allows the resulting images to be efficiently  transmitted,  viewed and manipulated over local area networks and the Internet. You can read and write files in this format. With ABC, there are also lossy options.  For more information on the qFactor values to control the ABC compression, refer to Compression Quality Factors.

The power behind LEADTOOLS ABC technology is LEADs new LOSSLESS black and white image compression. LEAD Technologies has been an early leader in turning the latest advancements in image compression into productive, functional implementations for commercial use. In addition, this SDK supports compressed ABC in a TIFF file, as single page or multi-page TIFF.

LEADTOOLS ABC helps companies optimize their scanned documents to save transmission/ bandwidth usage and server space, which in turn, results in savings of time and money. Many financial institutions such as banks and insurance companies back up their important documents by scanning them and archiving the resulting images to servers as TIFF files or other common bitonal file formats. Using LEADTOOLS ABC compression, server space can be significantly reduced, therefore eliminating the need for additional servers.   In addition, if the images are being transmitted over the internet, the smaller file sizes will save transmission costs and time since smaller file sizes transmit much faster using less bandwidth.
