PDF417 is a multi-row, variable-length symbology offering high data capacity and error-correction capability. One PDF417 symbol is capable of encoding more than 1100 bytes, 1800 ASCII characters, or 2700 digits, depending on the selected data compaction mode.
The SDK includes API [static library and dynamic library], ActiveX and ASP Component. Using the SDK, you can:
· Create PDF417 barcode symbols from alpha/numerical text/binary.
· Output barcode image with the formats such as BMP, GIF, JPEG, PNG.
· Render barcode images on any devices, and create device resolution dependent images.
· Full controls of the bar code image styles, such as background color, bar color, image quality, rotation angle, x-dimension, captions, etc.
· Chose four error correction levels according to the operating environment.
· Supprt version 1 to version 8,each version has a different module configuration or number of modules.
The PDF417 Encoder SDK Dynamic Library was designed to be a library of executable functins or data that can be used by a Windows Application. Typically, a DLL provides one or more particular functions and a program accesses the functions by creating either a static or dynamic link to the DLL. A static link remains constant during program execution while a dynamic link is created by the program as needed. DLLs can also contain just data. DLL files usually end with the extension .dll,.exe., drv, or .fon.
A DLL can be used by several applications at the same time. Some DLLs are provided with the Windows operating system and available for any Windows application. Other DLLs are written for a particular application and are loaded with the application.
You can use the library to develop application ,ActiveX, ATLCOM, ASP Cntrol, .Net Control and etc.using Microsoft Visual C++, Microsoft Visual Basic, Borland C++ Builder ,Borland Delphi or other development tools support to link static library.
Limitations:
· With 2D barcode encoder and decoder SDK, some of the input element will be replaced with char '*' before encoding, and some of the output element will be replaced with '*' after decoding.
· With 1D linear barcode encoder and decoder, some of the input element will be replaced with char '0' before encoding, and some of the output element will be replaced with '0' after decoding.
· The Trial version have 30 days' evaluation time, you must remove it from your computer and your application after expiration.
