Field Summary

Fields

Modifier and Type	Field	Description
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.
static final int	FILL	Value specifying fill operation to perform on the current path.
private GraphicsState	gs
static final int	NO_OP	End the path object without filling or stroking it.
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.
private int	operation
private int	rule
static final int	STROKE	Value specifying stroke operation to perform on the current path.

Field Details

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.

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

See Also:

• 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.

Constructor Details

PathPaintingRenderInfo

public PathPaintingRenderInfo(int operation,
 int rule,
 GraphicsState gs)

Parameters:

operation - One of the possible combinations of STROKE and FILL values or NO_OP

rule - Either NONZERO_WINDING_RULE or EVEN_ODD_RULE.

gs - The graphics state.

PathPaintingRenderInfo
