BarcodeFormatIds

BarcodeFormatIds is a parameter to specify the formats of the barcode in BarcodeFormat group 1 to be read. It is a combined value of BarcodeFormat Enumeration items.

Remarks

The default value is all supported barcode formats in BarcodeFormat group 1.
The barcode format our library will search for is composed of BarcodeFormat group 1 and BarcodeFormat group 2, so you need to specify the barcode format in group 1 and group 2 individually.

Setting Methods

BarcodeFormatIds is supported to be set through RuntimeSetting or JSON template.

As `PublicRuntimeSettings` Member

BarcodeFormatIds can be set dynamically during runtime as a member of PublicRuntimeSettings struct.
