createMathTransform
protected MathTransform createMathTransform(ParameterValueGroup values) throws ParameterNotFoundException Constructs anAffineTransform2D
math transform from the specified group of parameter values.The similarity transform is a particular case of Affine Transform 2D where:
m00 = SCALE * cos(ROTATION) m01 = SCALE * sin(ROTATION) m02 = TRANSLATION_1 m10 = -m01 m11 = m00 m12 = TRANSLATION_2
- Specified by:
createMathTransform

- Parameters:
values
- The group of parameter valuesPARAMETERS
.- Returns:
- an
AffineTransform2D
. - Throws:
ParameterNotFoundException
- if a required parameter was not found.- See Also:
