Class PolylineShapeIterator

public class PolylineShapeIterator extends Object implements PathIterator

PathIterator for PolylineShape. This class was originally written by wil - amristar.com.au and integrated into iText by Bruno.

Field Summary
protected AffineTransform	affine an affine transformation to be performed on the polyline.
protected int	index the index of the current segment in the iterator.
protected PolylineShape	poly The polyline over which we are going to iterate.

Constructor Summary
	PolylineShapeIterator(PolylineShape l, AffineTransform at) Creates a PolylineShapeIterator.

Method Summary
int	currentSegment(double[] coords) Returns the coordinates and type of the current path segment in the iteration.
int	currentSegment(float[] coords) Returns the coordinates and type of the current path segment in the iteration.
int	getWindingRule() Return the winding rule for determining the insideness of the path.
boolean	isDone() Tests if there are more points to read.
void	next() Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.

Field Detail

affine

protected AffineTransform affine

an affine transformation to be performed on the polyline.

index

protected int index

the index of the current segment in the iterator.

poly

protected PolylineShape poly

The polyline over which we are going to iterate.

Constructor Detail

PolylineShapeIterator

PolylineShapeIterator(PolylineShape l, AffineTransform at)

Creates a PolylineShapeIterator.

Method Detail

currentSegment

public int currentSegment(double[] coords)

Returns the coordinates and type of the current path segment in the iteration. The return value is the path segment type: SEG_MOVETO, SEG_LINETO, SEG_QUADTO, SEG_CUBICTO, or SEG_CLOSE. A double array of length 6 must be passed in and may be used to store the coordinates of the point(s). Each point is stored as a pair of double x,y coordinates. SEG_MOVETO and SEG_LINETO types will return one point, SEG_QUADTO will return two points, SEG_CUBICTO will return 3 points and SEG_CLOSE will not return any points.

getWindingRule

public int getWindingRule()

Return the winding rule for determining the insideness of the path.

isDone

public boolean isDone()

Tests if there are more points to read.

Returns: true if there are more points to read

public void next()

Moves the iterator to the next segment of the path forwards along the primary direction of traversal as long as there are more points in that direction.
