StrokeType enumeration
Indicates whether a stroke should be analyzed as part of a drawing or as part of writing.
typedef enum StrokeType {
StrokeType_Unclassified = 0,
StrokeType_Writing = 1,
StrokeType_Drawing = 2
} StrokeType;
-
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.
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);
}
