IInkStrokeDisp::PolylineCusps

4/8/2010

Gets an array that contains the indices of the cusps of the IInkStrokeDisp object.

Syntax

[propget] HRESULT get_PolylineCusps (
  [out, retval] VARIANT *PolylineCusps
);

Parameters

Return Value

HRESULT value Description

S_OK

Success.

E_POINTER

The parameter pointer was NULL or invalid.

E_OUTOFMEMORY

Cannot allocate memory for the array.

E_INK_EXCEPTION

An exception occurred inside the method.

Remarks

The array returned by the PolylineCusps property is an index into the array returned by the IInkStrokeDisp::GetPoints method. Each index in the PolylineCusps property corresponds to a point in the array returned by the GetPoints method that is a cusp of the points of the stroke.

A cusp is a point on the stroke where the direction of writing changes in a discontinuous fashion. For example, if the stroke represents the capital letter "L", this property returns three cusps: two corresponding to the first and last control points on the stroke and the third representing the corner of the "L".

The location of a cusp can be determined by using the cusp as an index into the array returned by the GetPoints method.
