StrokeType enumeration

Indicates whether a stroke should be analyzed as part of a drawing or as part of writing.

Syntax

typedef enum StrokeType { 
  StrokeType_Unclassified  = 0,
  StrokeType_Writing       = 1,
  StrokeType_Drawing       = 2
} StrokeType;

Constants

StrokeType_Unclassified

The stroke might be either part of a drawing or part of writing.

StrokeType_Writing

The stroke is part of writing.

StrokeType_Drawing

The stroke is part of a drawing.

Examples

The following example shows part of a stroke event handler, implemented in a similar fashion to the C++ Event Sinks Sample. The added stroke is checked to see if the top of its bounding box has been drawn below a margin, drawingMargin. If so, the IInkAnalyzer object, m_spInkAnalyzer, is set to analyze the stroke as a drawing stroke, rather than as a handwriting stroke. CheckHResult is a function that takes an HRESULT and a string, and throws an exception created with the string if the HRESULT is not SUCCESS.

IInkRectangle* bounds;
CheckHResult(pStroke->GetBoundingBox(IBBM_Default, &bounds), "IInkStrokeDisp::GetBoundingBox failed");
long top;
CheckHResult(bounds->get_Top(&top), "IInkRectangle::get_Top failed");
if (top > drawingMargin)
{
    long strokeId;
    CheckHResult(pStroke->get_ID(&strokeId), "IInkStrokeDisp::get_ID failed");
    m_pInkAnalyzer->SetStrokeType(strokeId, StrokeType_Drawing);
}
