Method Detail

scaleToFit

public static double scaleToFit(Dimension src,
                                Dimension dest)

Return the scale value from src to dest proportionally

Parameters:

src - source dimension

dest - destination dimension

Returns:

the scale value

getBounds2D

public static Rectangle2D getBounds2D(List<Shape> shapeList)

Return bounds for the supplied shapeList

Parameters:

shapeList - List of Shape

Returns:

bounds for the supplied shapeList

createShape

public static Shape createShape(String pathString)
                         throws IllegalArgumentException

Return Shape for the supplied pathString that conform to SVG d attribute

Parameters:

pathString - String that conform to SVG d attribute

Returns:

Shape

Throws:

IllegalArgumentException - when parse fail

simplify

public static List<Point2D> simplify(double tol,
                                     List<Point2D> pointList,
                                     List<Point2D> simplifyList)

Computes the simplified version of the pointList and approximation tolerance and stores on the simplifyList. If simplifyList is null a new List object is allocated.

Parameters:

tol - approximation tolerance in pixel

pointList - List of Point2D

simplifyList - List of Point2D or null

Returns:

simplifyList of Point2D

getPathSegType

public static int getPathSegType(String type)
