Method Detail

deltaTransformPoint

public static java.awt.geom.Point2D deltaTransformPoint(java.awt.geom.AffineTransform transform,
                                                        float x,
                                                        float y)

deltaTransformPoint

public static void deltaTransformPoint(java.awt.geom.AffineTransform transform,
                                       float[] pts)

deltaTransformPoint

public static void deltaTransformPoint(java.awt.geom.AffineTransform transform,
                                       java.awt.geom.Point2D pt)

inverseTransformRect

public static void inverseTransformRect(java.awt.geom.AffineTransform transform,
                                        java.awt.geom.Rectangle2D rect)

Transform a rectangle in device space to user space. The rectangle is modified. The coordinates of the result are normalized (lower left corner has smallest coordinate values).

Parameters:

transform - The transformation from user space to device space.

rect - The rectangle whose coordinates are transformed, the rectangle is modified.

normalizeRect

public static void normalizeRect(float[] pts)

normalizeRect

public static void normalizeRect(java.awt.geom.Rectangle2D rect)

Normalize the rectangle. The x and y value of the rectangle are updated to have the smallest coordinates (lower left corner).

Parameters:

rect - The rectangle whose coordinates are normalized, the rectangle is modified.

toFloatArray

public static float[] toFloatArray(java.awt.geom.Rectangle2D rect)

transformPoint

public static java.awt.geom.Point2D transformPoint(java.awt.geom.AffineTransform transform,
                                                   float x,
                                                   float y)

transformPoint

public static void transformPoint(java.awt.geom.AffineTransform transform,
                                  float[] pts)

transformPoint

public static void transformPoint(java.awt.geom.AffineTransform transform,
                                  java.awt.geom.Point2D pt)

transformRect

public static void transformRect(java.awt.geom.AffineTransform transform,
                                 float[] pts)

transformRect

public static void transformRect(java.awt.geom.AffineTransform transform,
                                 java.awt.geom.Rectangle2D rect)

Transform a rectangle, the rectangle is modified. The coordinates of the result are normalized (lower left corner has smallest coordinate values).

Parameters:

transform - The transformation from user space to device space.

rect - The rectangle whose coordinates are transformed, the rectangle is modified.
