  • 아티클

ConfidenceAlternates Property

Returns the collection of alternates in which each alternate in the collection consists of the segments with the same property values.

Declaration

[C++]

[propget] HRESULT get_ConfidenceAlternates (
    [out, retval] IInkRecognitionAlternates** RecognitionAlternates
);

[Microsoft® Visual Basic® 6.0]

Public Property Get ConfidenceAlternates() As IInkRecognitionAlternates

Property Value

IInkRecognitionAlternates Returns the IInkRecognitionAlternates collection of alternates, with each alternate in the collection having the same confidence value as this alternate. The method leaves the parameter intact if it fails.

This property is read-only.

Return Value

HRESULT value Description
S_OK Success.
E_POINTER IInkRecognitionAlternates is an invalid pointer.
E_INVALIDARG The recognition range is invalid.
E_INK_EXCEPTION An exception occurred while processing.
E_OUTOFMEMORY Out of memory.

Remarks

This property is an alternative to the AlternatesWithConstantPropertyValues method. For more information about properties of alternates, see the RecognitionProperty constants.

Example

[Visual Basic 6.0]

This Visual Basic 6.0 example uses the ConfidenceAlternates property to display the alternates within the top alternate divided by confidence level boundaries for the recognized ink.
