XRFillRule (Windows Embedded CE 6.0)
1/6/2010
This enumeration specifies how the intersecting areas of the objects that are contained in an IXRGeometry are combined to form the area of the IXRGeometry.
Syntax
enum XRFillRule
{
XRFillRule_EvenOdd=0,
XRFillRule_Nonzero=1
};
Members
- XRFillRule_EvenOdd
Rule that determines whether a point is in the fill region by drawing a ray from that point to infinity in any direction and counting the number of path segments within the given shape that the ray crosses. If this number is odd, the point is inside; if even, the point is outside.
- XRFillRule_Nonzero
Rule that determines whether a point is in the fill region of the path by drawing a ray from that point to infinity in any direction and then examining the positions where a segment of the shape crosses the ray. Starting with a count of 0, add one every time that a segment crosses the ray from left to right and subtract one every time that a path segment crosses the ray from right to left. After counting the crossings, if the result is 0, then the point is outside the path; otherwise, it is inside.
