This sdk is a library that allows therecognition of barcodes from scanned images.
The approach used for searching and decoding barcodes from images is based on aVirtual Laserthat, as a real laser gun, scans images looking for barcodes placed in every position.
You can specify several options fine tuning the recognition process:
Barcode types You can specify the types of barcode symbols to read, setting every combination from supportated standards:
2of5 Standard / 2of5 Matrix
2of5 IATA / 2of5 Airline
MSI / Plessey
EAN 13 / JAN / ISBN
Code 39 Extended
On demand we could also provide support for other standard or proprietary barcode symbols.
Virtual Laserhead size You can specify the size of virtual laser recognition head: with larger size you could have recognition of damaged barcodes, with smaller size you can recognize barcode having high skew instead.
Virtual Lasermoving step It's the step for moving the virtual laser recognition head vertically across the page: with large step you improve the speed, with small step you improve the accuracy.
Max Expected Codes per Image The maximum number of codes to find and read in a single image.
Min Code Length The minimum characters length expected for each code.
Max Code Length The maximum characters length expected for each code.
Image Quality The expected image quality, choiced between Normal, Dark, Light.
Orientation The expected barcode orientation, any cambination from:
Left to right
Right to left
Top to bottom
Bottom to top
Check digit verification flag The option allowing to enable or disable the check digit verification.
In addition to these options you have to supply themonochrome, grayscale or true-colorDIB (Device Independent Bitmap) to process.
WithRecogniform barcode engine, the procedure of recognition is very fast and accurate: a 300 DPI A4 page, full of contents, is usually processed in less then 0.1 seconds!
The library returns the number of recognized barcodes and for each one:
the decoded string
the position and the size
the check-digit presence and validity
the barcode type
To see how this library works, you candownload a demo application (200 KB)that allows you to recognize your bitmap images:please give us your feedback and your comments after the test !
The software development kit for barcode recognition is available also asroyalties freeLiteversion different fromProfessionalbecause it can reach 15 CPS as max speed. To increase the speed
you can purchase multiple licenses of lite royalties free version, so that purchasing 2 licenses you will get a 30 CPS speed, purchasing 3 liceneses you get a 45 CPS speed and so on...
