Параметры

s
Тип: Microsoft.Ink.Strokes
The Strokes collection contained within the alternate.

selectionStart
Тип: System.Int32%
The start position of the range of recognized text.

selectionLength
Тип: System.Int32%

Заметки

Use this method to retrieve the text that corresponds to a specified range of Stroke objects. For example, consider a Strokes collection, "how are you", that was drawn using nine strokes (one for each letter and three for each word). If a collection that consists of the sixth and seventh strokes is passed in, corresponding to characters "e" and "y", the text range returned matches the alternate containing "are you" and the selection start and length matches this substring.

Примеры

This C# example calls the GetTextRangeFromStrokes method on the TopAlternate property of a RecognitionResult object, theRecognitionResult, passing in a Strokes collection from within the strokes that make up the recognition result in theStrokes.

[C#]

// . . .
int theStart = 0;
int theLength = 0;
theRecognitionResult.TopAlternate.GetTextRangeFromStrokes(theStrokes, ref theStart, ref theLength);
// . . .

This Visual Basic .NET example calls the GetTextRangeFromStrokes method on the TopAlternate property of a RecognitionResult object, theRecognitionResult, passing in a Strokes collection from within the strokes that make up the recognition result in theStrokes.

[Visual Basic]

' . . .
Dim theStart As Integer = 0
Dim theLength As Integer = 0
TheRecognitionResult.TopAlternate.GetTextRangeFromStrokes(theStrokes, _
    theStart, theLength)
