The Black Ice PDF 417 Barcode SDK/ActiveX toolkit allows developers to add 2D PDF 417 writing and reading to their applications. The Black Ice PDF 417 Barcode SDK/ActiveX toolkit is a robust and efficient 2D PDF 417 barcode library for reading/decoding, searching barcodes, and detecting barcode orientation.
PDF 417, or Portable Data File 417, is a two-dimensional stacked bar code capable of encoding over a kilobyte of data per label. This is useful for situations when a bar code will be used to store a substantial amount of data about an item, allowing developers to avoid database interaction. Since a PDF 417 barcode symbol can store a substantial amount of information, item specific data, such as the content of a shipping manifest or equipment maintenance history, can be stored directly on the item, without requiring access to a database.
Developers can read barcodes regardless of orientation, skewing or flipping. Barcodes can be detected and read from specific areas of interest. When combined with additional Black Ice Imaging toolkits, barcodes can be read from a variety of supported image file formats and can be acquired from scanners or digital cameras.
Encoding data into a PDF417 bar code is a two-step process. First, data is converted into codeword values of 0 - 928, which represent the data. This is “high-level encoding." Then the values are physically represented by particular bar/space patterns, which is “low-level encoding." Decoding is the reverse process.
The Black Ice PDF 417 Barcode SDK/ActiveX toolkits are written to be image toolkit independent, and can be used with any Black Ice imaging toolkit, such as the TIFF SDK/ActiveX , the Image SDK/ActiveX , or the Document Imaging SDK/ActiveX. They can also be used with any third party imaging platform.
The PDF417 Barcode SDK/ActiveX contains a variety of sample applications, which demonstrate the capabilities and features of the toolkit. The product is fully .NET compatible and also provides sample source code written in C#, VB.NET, and J# to demonstrate the powerful document conversion options.
