LEADTOOLS Barcode C++ Class Library Help

Barcode Symbols code data in machine-readable form. A number of international and national standards govern what data can be encoded, and how, for many industry sectors.
LEADTOOLS Barcode Module functions allow you to easily enable your applications to read barcodes, write barcodes and find duplicate barcodes within any image.
LEADTOOLS Barcode Modules are the most comprehensive barcode toolkits on the market, supporting reading and writing of over 100 types and sub-types, including all major 1-dimensional [Linear (1D)], and 2-dimensional [DataMatrix (2D), PDF 417 (2D), MicroPDF417(2D) and QR (2D)] barcodes.
LEADTOOLS offers the fastest barcode recognition speed available. LEADTOOLS Barcode Modules can recognize barcodes faster than other commercial engines. Our superior speed opens up the bottle neck in high speed scanning applications and allows you to maximize the benefits of high speed processors.
LEADTOOLS is designed to allow our developers to add new barcode types and sub-types. If you find a barcode that we cannot recognize, we can quickly update our engine to add it.
LEADTOOLS makes integrating barcode functionality into your application simple and easy - one function reads barcodes, and one other writes them. We have sample applications with source code ready for you to cut and paste into your project.
LEADTOOLS Barcode Modules support both bitonal and color barcode images.
LEADTOOLS has optimized and trained our barcode engines to provide very high accuracy even on images of poor quality. The better the accuracy, the less human interaction required: resulting in substantial savings of time and money.
LEADTOOLS Barcode Modules add on to the LEADTOOLS Raster, Document, Medical, and Vector Imaging toolkits. The Document Imaging SDK includes powerful document image processing and enhancement technology that allows the developer to clean noisy or damaged images to improve barcode and OCR accuracy.

Key Features:
Includes all popular barcode types: Linear (1D) Symbols, DataMatrix (2D), PDF 417 (2D), MicroPDF417(2D), and QR (2D) modules are available
High-speed, highly accurate barcode recognition. All barcodes in an image are located and reported back in fractions of a second.
Report back comprehensive information for all detected barcodes such as the barcode type, data string, X/Y position, bounding rectangle, check digit, etc.
Read/write barcodes at any orientation, independent of skew, orientation, or flipping, from anywhere in the image or region of interest, acquired from scanner or digital camera.
Read/write barcodes from/to any of over 150+ supported raster image file formats
Read/write multiple barcodes
Read/write barcodes with specified colors
Contains Error Correction Code (ECC) to detect and repair damaged barcode symbols.
Write barcodes to any windows-compliant printer
Integrate LEADTOOLS' extensive image processing technologies for complete control over your barcode recognition process.
