Constructors

BaseOCR(nint, nint, Action<nint>)

Factory-pattern constructor. smartPtr is a cv::Ptr<T>* that owns the object lifetime; rawPtr is the T* extracted from it for P/Invoke.

protected BaseOCR(nint smartPtr, nint rawPtr, Action<nint> releaseSmartPtr)

Parameters

smartPtr nint

rawPtr nint

releaseSmartPtr Action<nint>
