Creating Barkoder Configuration #
Python

print("SDK status: ", status)Enabling Symbologies #
Python
QR = BarkoderSDK.constants["Decoders"]["QR"];

BarkoderSDK.setEnabledDecoders(decoders);Setting Barkoder Settings #
Python
#set desired decodingSpeed

BarkoderSDK.setDecodingSpeed(decodingSpeed);
#set desired ROI
BarkoderSDK.setRegionOfInterest(0, 0, 100, 100);
#set desired DPM mode
BarkoderSDK.setDatamatrixDpmModeEnabled(False);Performing a Decode / Scan #
Python
#---------------read and scan an image---------

Python
#---------------handle the result--------------
