IInkStrokeDisp::SelfIntersections
4/8/2010
Returns the self–intersections of the IInkStrokeDisp object.
Syntax
[propget] HRESULT get_SelfIntersections (
[out, retval] VARIANT *SelfIntersections
);
Parameters
SelfIntersections
An array of floating point index values that represents the self-intersections of a IInkStrokeDisp object.This property is read only.
For more information about the VARIANT structure, see Using the Automation Library with Windows Mobile Ink.
Return Value
| HRESULT value | Description |
|---|---|
S_OK |
Success. |
E_POINTER |
The parameter pointer was NULL or invalid. |
E_OUTOFMEMORY |
Cannot allocate memory for the points. |
E_INK_EXCEPTION |
An exception occurred inside the method. |
Remarks
A self-intersection is the point of a stroke where the stroke crosses over itself.
A floating point index is a float value that represents a location somewhere between two points in the stroke. As examples, if 0.0 is the first point in the stroke and 1.0 is the second point in the stroke, 0.5 is halfway between the first and second points. Similarly, a floating point index value of 37.25 represents a location that is 25 percent along the line between points 37 and 38 of the stroke.
Note
A floating point index is returned for each intersection and line segment combination. If a stroke has one intersection, this property returns two self intersections, one for each line segment that is part of the intersection.
