Description

Scans for barcodes in a picture.
Please use Barcode.LoadLibrary once in start script to load zbar library before using this function.
Works best with black & white picture, so you may enhance contrast.

ZBar is an open source software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 and QR Code.

ZBar is licensed under the GNU LGPL 2.1 to enable development of both open source and commercial projects.

For FileMaker Go, please use PSoS and do the scan server side. Or build your own app based on the FileMaker iOS SDK with Xcode and embed the MBS Plugin and the zbar library for on device detection.
