VeryPDF Barcode Recognition SDK is available for Mobile iOS/Android, .NET Developer SDKs to read and write barcodes. Read Code39, Code128, PDF417, DataMatrix, QR, and other barcodes from TIF, PDF and other image documents. VeryPDF Barcode Recognition SDK is a highly accurate and powerful developer library which recognizes 1-D and 2-D barcodes from digital images, bitmaps, PDF files and scanned documents. Using this SDK you can integrate barcode recognition functionality to your document processing systems, Windows applications, embedded systems (Windows CE, Pocket PC, Smartphone), Android, iOS and Web services. The following image formats are supported: PNG, BMP, TIF, JPG, PNG and multipage TIF and PDF (Portable Document Format). The unique and fast barcode recognition algorithm searches for barcodes in any position and orientation from your images. The royalty free VeryPDF Barcode Recognition SDK allows you to read barcode symbols from C, C++, C#, VB6, VB.NET, Java, Delphi, PHP and other programming languages which support dynamic library loading, COM or .NET. By using our Barcode API you will be able to integrate barcode reading functionality into your application within several hours or even less. VeryPDF Barcode Recognition COM/SDK supports COM and SDK interfaces. Provide a COM interface for PHP, Ruby, Python, C#, VB, VB.NET, C++, ASP, JavaScript, VBScript, etc. program languages. Read barcodes from PNG, BMP, TIF, JPG, PNG and multipage TIF and PDF, etc. formats. Read 1D barcodes (such as Code 39, Code 128, etc.) and 2D barcode: PDF417, DataMatrix, and QR code, etc. Read barcodes printed on scanned paper documents. Read barcodes embedded in PDF files. Recognize 2D formats like PDF417, DataMatrix, Aztec and QR Code. Recognize 30 different 1D barcode formats, Code 39, Codabar, UPC, Code 128, EAN 13, 2 of 5, etc. Recognize postal barcodes like Planet, PostNet, Royal Post and Australian Post. Speed & Accuracy: Read multiple barcodes at up to 1,000 pages per minute while accurately locating and decoding multiple barcodes on each page. Multiple Platforms: Get the same great accuracy and speed on all of your languages/platforms. Platforms: Windows, Linux, Mac, Android, iOS. Languages: .NET/WPF, JAVA, C/C++, Objective-C, PHP, VBScript, Javascript, Delphi, ASP, etc. Fast, accurate and reliable barcode detection, reading and writing for use in any application or environment. Read barcodes of any quality at any orientation. Multithreaded support for running barcode in high-performance, server-based applications. Supports both color and bitonal (black and white) images. Easy to integrate into any application with only a few lines of code. Error-correcting Codes (ECC) provide enhanced accuracy in low-quality images. Return recognized barcodes with 100% confidence.
