CWIMAQDataMatrixPolarities Enumeration
CWIMAQDataMatrixPolarities are the constants that specify what polarity of Data Matrix barcode the method searches for.
You can use the following constants with this data type:
- cwimaqDataMatrixPolarityAutoDetect—The method should determine the polarity of the Data Matrix barcode.
- cwimaqDataMatrixPolarityBlackOnWhite—The method should search for a Data Matrix barcode with dark data on a bright background.
- cwimaqDataMatrixPolarityWhiteOnBlack—The method should search for a Data Matrix barcode with bright data on a dark background.
