LEADTOOLS Barcode C++ Class Library Introduction
Summary
The LEADTOOLS Barcode C++ Class Library provides functions to detect, read, and write barcodes in images.
The Class Library features a fast, highly accurate, and reliable barcode software engine that outperforms most hardware-supported barcode read products. Fast document scanners can maintain full speed while performing barcode recognition operations on-the-fly for document-indexing purposes.
Programmers can integrate this technology into their applications in just a few lines of code, see Barcode Tutorial). Use the toolkit to easily add barcode support for reading and writing over 100 different 1D and 2D barcode symbology types and sub-types, including UPC, EAN, Code 39, Code 128, ITF (2 of 5), CodaBar, GS1 DataBar (formerly RSS14), QR, Data Matrix, PDF417, and Aztec.

Supported Environments
Cloud Services
Does your application require document recognition or conversion, but its implementation language is preventing you
from using LEADTOOLS directly? Consider using the LEADTOOLS Cloud Services Web API instead. It is a
high-powered and scalable Web API. Its hassle-free interface can be used to integrate advanced OCR, barcode, MICR,
and document conversion into any application.
