 PtQRDecode
is a Software Development
Kit (SDK)
to recognize QR Code (QRCode) 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:
JIS
X 0510
ISO/IEC
18004
Storage
capacity:
QR
Code (QRCode) is capable of handling all types of data, such as numeric and
alphabetic characters, Kanji, Kana, Hiragana, binary, and
control codes. Up to 7,089 characters can be encoded in one symbol.
The information stored in a symbol depends on the mix of ASCII,
numeric and hex data. Each symbol can encode 4296 ASCII
characters in Text Compaction mode, 2953 bytes in Byte Compaction
mode, or 7089 numerical digits in Numeric Compaction mode.
The SDK supports Text, Numeric and Byte Compaction modes.
Error
Correction Code:
The
SDK supports error correction level L(7%), M(15%), Q(25%), H(30%).
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 one module and the quality
of image. The recognition algorithm can overcome multiform
defects in images (scratch, smudges, damage, fuzzy code, etc.)
If the pixel of one module is no less than 2.5 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).
