EMatrixCodeReader::Learn

This method is deprecated.

Tries to locate, decode and read the Data Matrix code in the given ROI.

Namespace: Euresys::Open_eVision

[C++]

EMatrixCode Learn(
   const EROIBW8& roi
)

Parameters

roi

ROI in which the Data Matrix has to be found.

Remarks

If successful, it adds the parameters of the Data Matrix code found into the internal learning database. The decoding results can be found in the returned EMatrixCode object. The addition of the parameters of the Data Matrix code found into the internal learning database means that subsequent Read operations will be faster, but can only be performed on similar Data Matrix codes/conditions. Only the parameters that are tagged for learning are remembered for the subsequent EMatrixCodeReader::Read operations (see EMatrixCodeReader::SetLearnMaskElement). See the EMatrixCode::Found property for information about the outcome of the Learn process.
