IInkRecognizerContext::get_PrefixText method (msinkaut.h)

Gets or sets the characters that come before the InkStrokes collection in the InkRecognizerContext object.

This property is read/write.

Syntax

HRESULT get_PrefixText(
  BSTR *Prefix
);

Parameters

Prefix

Return value

None

Remarks

The prefix helps improve recognition results by supplying the recognizer with more context about the handwriting.

Setting the PrefixText property succeeds only if the Strokes property is NULL. You must set the PrefixText property before you attach a InkStrokes collection to the Strokes property of the InkRecognizerContext, or you must set the Strokes property to NULL and then set the PrefixText property.

The prefix text is ignored unless you have set both the IRM_Coerce and IRM_WordModeInkRecognitionModes flags in the RecognitionFlags property.

The SuffixText property gets or sets the characters that come after the InkStrokes collection in the InkRecognizerContext object and also helps improve the recognition result.

If your application provides a correction interface when converting ink to text, the application may allow the user to select characters within a word and use the stylus to generate replacement characters. Your application can use the PrefixText and SuffixText properties to improve recognition of the new ink.
