 PtPDF417Decode is a
Software Development Kit (SDK)
to recognize PDF417 barcode from images.
The SDK runs under
Windows, Unix/Linux, Win CE( Windows Mobile, Pocket PC, Smartphone)
, Symbian, Android and iPhone/Mac OS. On Windows, WinCE/WinMobile and Symbian
platform,
the SDK comes with dynamic link library (dll), and supports VC/VB/.Net etc.. On
iPhone/Mac OS, Android and Unix /Linux platform,
the SDK comes with static lib(a) or share object(so).
The SDK is easy to use.
You can
download the Free Trial SDK and Demo to evaluate the quality of our barcode recognition
engine before ordering. If you have a special requirement or need we would be glad to
customize our product for your specific application.
Standards:
ANSI/AIM
USS PDF417
ISO/IEC 15438
GB/T17172-1997
Storage
capacity:
The
SDK supports Text, Numeric and Byte Compaction modes. The information
stored in a symbol depends on the mix of ASCII, numeric and hex data. Each
symbol can encode 1850 ASCII characters in Text Compaction mode, 1108
bytes in Byte Compaction mode, or 2710 numerical digits in Numeric
Compaction mode.
Error
Correction Code:
The
SDK supports error correction level 0-8. The error correction algorithm
can recover the data from the barcode even with severe damage.
Recognition
rates:
Recognition
rates depend on the pixel number of the X-dimension and the quality
of image. The recognition algorithm can overcome multiform
defects in images (scratch, smudges, damage, fuzzy code, etc.) If
the width of the X-dimension is no less than 2 pixels, the performance of
the SDK is good enough. If no less than three pixels, our engine can get
a recognition rate of nearly 100%.
Barcode
orientation:
The SDK supports any degree (0-360),
such as horizontal, vertical,
diagonal and upside-down.
Barcode
Location:
The
SDK can detect the barcode anywhere in the whole image or in the area
specified by users.
Number
of barcodes:
The SDK can detect the all barcodes in
the image. Users also can limit the number of barcode to be searched
through SDK interface.
Image File Format:
The SDK supports almost all
image file format such as BMP/TIFF/JPG/GIF/PNG/TGA/PCX/JPG2000 etc.
(with the support of PtImageRW).
