IInkStrokeDisp::get_BezierCusps method (msinkaut.h)

Article
02/22/2024

Gets an array that contains the indices of the cusps of the Bezier approximation of the stroke.

This property is read-only.

Syntax

HRESULT get_BezierCusps(
  VARIANT *Cusps
);

Parameters

Cusps

Return value

None

Remarks

Note The array of Bezier control points that the BezierPoints property returns are made up of x and y values. The BezierCusps property refers only to the x values in this array. The y values can be retrieved by an action similar to the following below.

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 following code extracts the x and y values of the Bezier cusps of an IInkStrokeDisp, theStroke, and stores them in a two-dimensional array called BezierCuspValues.
