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. 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.
The power behind LEADTOOLS ABC technology is LEAD’s 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. With ABC, there are also lossy options. You can specify the quality factor using QualityFactor.
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.
Features
-
Superior Compression - Outperforms JBIG2, LZW, TIF and other 1-bit compression format types. Several save/compression options are available to allow you to find your optimal file size.
-
Save Time and Money - Reduce the need for purchasing additional bandwidth and or server space by using LEADTOOLS ABC to compress your files five times smaller than TIF G4. You will also save substantial time in transmission of image files over networks and the internet.
-
Proprietary Format - LEADTOOLS ABC is a proprietary format created by LEAD’s R&D department to produce the smallest real-time lossless compression, with maximum control of the new technology features and capabilities. No more waiting on committees to update standards or guidelines.
