Method Detail

flush

public void flush()
           throws IOException

Description copied from interface: PathConstructor

Flushes any cached info to the output file. The path is complete at this point.

Specified by:

flush in interface PathConstructor

Throws:

IOException

addPath

public boolean addPath(Shape s)
                throws IOException

Description copied from interface: PathConstructor

Adds the points of the shape using path construction operators. The path is neither stroked nor filled.

Specified by:

addPath in interface PathConstructor

Returns:

true if even-odd winding rule should be used, false if non-zero winding rule should be used.

Throws:

IOException

addPath

public boolean addPath(Shape s,
                       AffineTransform transform)
                throws IOException

Description copied from interface: PathConstructor

Adds the points of the shape using path construction operators, using the given transform. The path is neither stroked nor filled.

Specified by:

addPath in interface PathConstructor

Returns:

true if even-odd winding rule should be used, false if non-zero winding rule should be used.

Throws:

IOException

public static boolean addPath(PathConstructor out,
                              Shape s,
                              AffineTransform transform)
                       throws IOException

Throws:

IOException

isEvenOdd
