How to read an inverted barcode?
Typically, normal barcode images include a dark barcode on a light background. An inverted image in this case would have a light barcode on a dark background instead. In order to read those types of barcodes, the
grayscaleTransformationModes array of
furtherModes must prioritize
GTM_INVERTED like shown in the below example.
settings.furtherModes.grayscaleTransformationMode = Dynamsoft.DBR.EnumGrayscaleTransformationMode.GTM_INVERTED; await scanner.updateRuntimeSettings(settings);
