EMatrixCodeReader::LearnMore

This method is deprecated.

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

Namespace: Euresys::Open_eVision

[C++]

EMatrixCode LearnMore(
   const EROIBW8& roi
)

Parameters

roi

ROI in which the Data Matrix has to be found.

Remarks

If successful, it cumulates the parameters of the Data Matrix code found with those already present in the internal learning database. The decoding results can be found in the returned EMatrixCode object. The cumulation of the parameters of the Data Matrix code found with those already present in 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 LearnMore process.
