Constants

RC_None

No capabilities specified.

RC_DoNotCare

Ignores all other flags that are set.

RC_Object

Supports object recognition; otherwise, recognizes only text.

RC_FreeInput

Supports free input, where ink is entered without the use of a recognition guide, such as a line or a box.

RC_LinedInput

Supports lined input, which is similar to writing on lined paper.

RC_BoxedInput

Supports boxed input, where each character or word is entered in a box.

RC_CharacterAutoCompletionInput

Supports character Autocomplete. Recognizers that support character Autocomplete require boxed input.

RC_RightAndDown

Supports handwriting input in right and down order, such as in western languages and some East Asian languages.

RC_LeftAndDown

Supports handwriting input in left and down order, such as in Hebrew and Arabic languages.

RC_DownAndLeft

Supports handwriting input in down and left order, such as in some East Asian languages.

RC_DownAndRight

Supports handwriting input in down and right order, such as in some East Asian languages.

RC_ArbitraryAngle

Supports text written at arbitrary angles.

RC_Lattice

Supports returning a lattice as an alternative a string for handwriting recognition results.

RC_AdviseInkChange

Supports interrupting background recognition, such as when the ink has changed.

RC_StrokeReorder

Supports that stroke order, spatial and temporal, is handled as part of the recognition operation. The IInkAnalyzer does not reorder strokes before sending ink to the IInkAnalysisRecognizer.

RC_Personalizable

Supports personalized handwriting, where the recognizer improves recognition when exposed to the same handwriting over time.

RC_PrefersArbitraryAngle

The IInkAnalyzer need not rotate the handwriting to a horizontal orientation before sending the ink to the IInkAnalysisRecognizer.

RC_PrefersParagraphBreaking

The IInkAnalyzer should send entire paragraphs of ink to the IInkAnalysisRecognizer, allowing the IInkAnalysisRecognizer to do the line breaking and word (or character) breaking.

RC_PrefersSegmentationRecognition

Recognizes only one word or character per recognition operation. The IInkAnalyzer performs segmentation on the handwriting and sends only one segment at a time to the IInkAnalysisRecognizer.

Remarks

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