Barcodes

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 functions allow you to easily enable your applications to read barcodes, write barcodes and find duplicate barcodes within any image.

• LEADTOOLS Barcode toolkits are the most comprehensive barcode toolkits on the market, supporting reading and writing of over 100 different 1D and 2D barcode symbologies (including sub-types):

  • 1-Dimensional (1D) barcodes, i.e., linear barcodes.
  • 2D barcodes, i.e., DataMatrix, PDF 417, MicroPDF417, QR, Aztec, Maxi and MicroQR barcodes.

• LEADTOOLS offers the fastest barcode recognition speed available. LEADTOOLS Barcode toolkits can recognize barcodes faster than other commercial engines.  Our superior speed opens up the bottleneck 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 toolkits 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 is included in the LEADTOOLS Barcode Pro, Pro Suite, Document, and Medical 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.

• 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.

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.
