This sdk is a library that allows the recognition of barcodes from scanned images. The approach used for searching and decoding barcodes from images is based on a Virtual Laserthat, as a real laser gun, scans images looking for barcodes placed in every position.

Barcode types
You can specify the types of barcode symbols to read, setting every combination from supportated standards
Interleaved 2of5
2of5 IATA / 2of5 Airline
2of5 Industrial
2of5 Datalogic
2of5 Standard / 2of5 Matrix
Code 11
Code 39
Code 128
Codabar
MSI / Plessey
EAN 13 / JAN / ISBN
EAN 8
UPCA A
UPCA E
EAN/UPC EXT2
EAN/UPC EXT5
PharmaCode
Code39 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 the monochrome, gray-scale or true-color DIB (Device Independent Bitmap) to process.
With Recogniform 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
the orientation
