public class PathPaintingRenderInfo
extends Object

Contains information relating to painting current path.

Since:

5.5.6

Field Summary

static int	EVEN_ODD_RULE The even-odd rule determines whether a point is inside a path by drawing a ray from that point in any direction and simply counting the number of path segments that cross the ray, regardless of direction.
static int	FILL Value specifying fill operation to perform on the current path.
static int	NO_OP End the path object without filling or stroking it.
static int	NONZERO_WINDING_RULE The nonzero winding number rule determines whether a given point is inside a path by conceptually drawing a ray from that point to infinity in any direction and then examining the places where a segment of the path crosses the ray.
static int	STROKE Value specifying stroke operation to perform on the current path.

Constructor Summary

PathPaintingRenderInfo(int operation, GraphicsState gs)
If the operation is NO_OP then the rule is ignored, otherwise NONZERO_WINDING_RULE is used by default.

Field Detail

NONZERO_WINDING_RULE

public static final int NONZERO_WINDING_RULE

The nonzero winding number rule determines whether a given point is inside a path by conceptually drawing a ray from that point to infinity in any direction and then examining the places where a segment of the path crosses the ray. Starting with a count of 0, the rule adds 1 each time a path segment crosses the ray from left to right and subtracts 1 each time a segment crosses from right to left. After counting all the crossings, if the result is 0, the point is outside the path; otherwise, it is inside. For more details see PDF spec.

Constant Field Values

EVEN_ODD_RULE

public static final int EVEN_ODD_RULE

The even-odd rule determines whether a point is inside a path by drawing a ray from that point in any direction and simply counting the number of path segments that cross the ray, regardless of direction. If this number is odd, the point is inside; if even, the point is outside. For more details see PDF spec.

Constant Field Values

NO_OP

public static final int NO_OP

End the path object without filling or stroking it. This operator shall be a path-painting no-op, used primarily for the side effect of changing the current clipping path

Constant Field Values

STROKE

public static final int STROKE

Value specifying stroke operation to perform on the current path.

Constant Field Values

FILL

public static final int FILL

Value specifying fill operation to perform on the current path. When the fill operation is performed it should use either nonzero winding or even-odd rule.
