Leadtools.Barcode Introduction


Detect, read, and write barcodes in images with LEADTOOLS Barcode technology.

LEADTOOLS barcode recognition SDK features a fast, highly accurate, and reliable barcode engine that outperforms most hardware-supported barcode read products. This software engine permits fast document scanners to maintain full speed while performing barcode recognition operations on-the-fly for document-indexing purposes.

The toolkit allows programmers to integrate this technology into their applications in just a few lines of code (for an example, refer to 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. Supported Barcode Symbologies include UPC, EAN, Code 39, Code 128, ITF (2 of 5), CodaBar, GS1 DataBar (formerly RSS14), QR, Data Matrix, PDF417, and Aztec.

For background and full details, see Barcode Technology.

LEADTOOLS Barcode technology is included in the Barcode Pro, Pro Suite, Document, and Medical toolkits.

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.
