Заметки

Because so many variations exist between users' handwriting, handwriting recognizers can sometimes convert handwriting into text that is different from what the user intended. When an InkAnalyzer performs analysis on a Strokes collection, the InkAnalyzer finds the most likely set of words that the handwriting represents. In addition, the InkAnalyzer also finds sets of alternative recognition matches, which are stored in an AnalysisAlternateCollection. In order for a user to take advantage of recognition alternates, you must create a user interface that allows the user to select the correct AnalysisAlternate.

AnalysisAlternate objects are generally obtained through the InkAnalyzer.GetAlternates method. The first AnalysisAlternate object in the collection is what the InkAnalyzer considers to be the most likely alternate.

Примеры

This example calls GetAlternates on an InkAnalyzer, theInkAnalyzer. It then loops through the AnalysisAlternateCollection and populates a ListBox, alternatesListBox, with all of the alternates that do not have an InkRecognitionConfidence of Poor recognition confidence.

alternatesListBox.Items.Clear()
' ContextNodeCollection selectedSubNodes is obtained via
' DirectCast(theInkAnalyzer.RootNode, RootNode).GetNodesFromTextRange(selStart, selLength);
Me.currentAlternates = theInkAnalyzer.GetAlternates(selectedSubNodes)
Dim alternate As AnalysisAlternate
For Each alternate In Me.currentAlternates
    ' Add only those that are not Poor confidence
    If alternate.InkRecognitionConfidence <> _
       Microsoft.Ink.InkRecognitionConfidence.Poor Then
        alternatesListBox.Items.Add(alternate.RecognizedString)
    End If
Next alternate

            alternatesListBox.Items.Clear();
            // ContextNodeCollection selectedSubNodes is obtained via
            // ((RootNode)theInkAnalyzer.RootNode).GetNodesFromTextRange(ref selStart, ref selLength);
            this.currentAlternates = theInkAnalyzer.GetAlternates(selectedSubNodes);
            foreach (AnalysisAlternate alternate in this.currentAlternates)
            {
                // Add only those that are not Poor confidence
                if (alternate.InkRecognitionConfidence !=
                    Microsoft.Ink.InkRecognitionConfidence.Poor)
                {
                    alternatesListBox.Items.Add(alternate.RecognizedString);
                }
            }
