InkRecognizerCapabilities Enumeration

Defines values that specify the attributes of an ink recognizer.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace:  System.Windows.Ink.AnalysisCore
Assembly:  IACore (in IACore.dll)

public enum InkRecognizerCapabilities

Member nameDescription
NoneNo capabilities specified.
DoNotCareIgnores all other flags that are set.
ObjectSupports object recognition; otherwise, recognizes only text.
FreeInputSupports free input, where ink is entered without the use of a recognition guide, such as a line or a box.
LinedInputSupports lined input, which is similar to writing on lined paper.
BoxedInputSupports boxed input, where each character or word is entered in a box.
CharacterAutoCompletionInputSupports character Autocomplete. Recognizers that support character Autocomplete require boxed input.
RightAndDownSupports handwriting input in right and down order, such as in western languages and some East Asian languages.
LeftAndDownSupports handwriting input in left and down order, such as in Hebrew and Arabic languages.
DownAndLeftSupports handwriting input in down and left order, such as in some East Asian languages.
DownAndRightSupports handwriting input in down and right order, such as in some East Asian languages.
ArbitraryAngleSupports text written at arbitrary angles.
LatticeSupports returning a Lattice object as an alternative to String for handwriting recognition results.
AdviseInkChangeSupports interrupting background recognition, such as when the ink has changed.
StrokeReorderSupports that stroke order—spatial and temporal—is handled as part of the recognition operation. The InkAnalyzerBase does not reorder strokes before sending ink to the InkRecognizerBase.
PersonalizableSupports personalized handwriting, where the recognizer improves recognition when exposed to the same handwriting over time.
PrefersArbitraryAngleSupports an option available under the InkAnalyzerBase - of not rotating handwriting to a horizontal orientation before sending the ink to the InkRecognizer.
PrefersParagraphBreakingIndicates that the InkAnalyzerBase should send entire paragraphs of ink to the InkRecognizerBase, allowing the InkRecognizerBase instances to do the line breaking and word (or character) breaking.
PrefersSegmentationRecognitionRecognizes only one word or character per recognition operation. The InkAnalyzerBase performs segmentation on the handwriting and sends only one segment at a time to the InkRecognizerBase.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values. Use this enumeration to find an installed ink recognizer that supports the attributes you need.

The following example demonstrates the InkRecognizerCapabilities enumeration.
