public class Shear
extends Transform

This class represents an Affine object that shears coordinates by the specified multipliers. The matrix representing the shearing transformation around a pivot point (pivotX, pivotY) with multiplication factors x and y is as follows:

             [   1   x   0   -x*pivotY   ]
             [   y   1   0   -y*pivotX   ]
             [   0   0   1       0       ]

For example:

Text text = new Text("Using Shear for pseudo-italic font");
text.setX(20);
text.setY(50);
text.setFont(new Font(20));

text.getTransforms().add(new Shear(-0.35, 0));
