Property Value

true to use double pass when reading Datamatrix symbols. Otherwise, false. The default value is false.
Remarks

When reading 2D barcodes, LEADTOOLS can perform internal auto preprocessing on the image and try again if the engine cannot detect the barcode required. This may take extra processing and increase the barcode detection time. Therefore, it is not recommended to always have EnableDoublePass enabled except in certain situations:

Example

For an example, refer to DatamatrixBarcodeReadOptions.
