XPS_FILL_RULE enumeration

The rule used by a composite shape to determine whether a given point is part of the geometry.

Syntax


typedef enum  { 
  XPS_FILL_RULE_EVENODD  = 1,
  XPS_FILL_RULE_NONZERO
} XPS_FILL_RULE;

Constants

XPS_FILL_RULE_EVENODD

The rule that determines whether a point is in the fill region. This is determined by drawing a ray from the point to infinity in any direction, and counting the number of path segments within the shape that the ray crosses. If this number is odd, the point is inside; if even, the point is outside.

XPS_FILL_RULE_NONZERO

The rule that determines whether a point is in the fill region of the path. This is determined by drawing a ray from the point to infinity in any direction, and examining the places where a segment of the shape crosses the ray. Start the count at 0, then add 1 whenever a path segment crosses the ray from left to right; subtract 1 whenever a path segment crosses the ray from right to left. After the crossings are counted, the point is outside the path if the result is zero and inside if otherwise.
