Constructor Details

ConcatenatedTransform2D

ConcatenatedTransform2D(org.opengis.referencing.operation.MathTransform transform1,
 org.opengis.referencing.operation.MathTransform transform2)

Constructs a concatenated transform.

Method Details

isValid

boolean isValid()

Checks if transforms are compatibles with this implementation.

Overrides:

isValid in class ConcatenatedTransform

transform

public Point2D transform(Point2D ptSrc,
 Point2D ptDst)
                  throws org.opengis.referencing.operation.TransformException

Transforms the specified ptSrc and stores the result in ptDst. This method is a copy of AbstractMathTransform2D.transform(Point2D, Point2D).

Specified by:

transform in interface org.opengis.referencing.operation.MathTransform2D

Throws:

org.opengis.referencing.operation.TransformException

createTransformedShape

public Shape createTransformedShape(Shape shape)
                             throws org.opengis.referencing.operation.TransformException

Transforms the specified shape.

Specified by:

createTransformedShape in interface org.opengis.referencing.operation.MathTransform2D

Parameters:

shape - shape to transform.

Returns:

transformed shape.

Throws:

org.opengis.referencing.operation.TransformException - if a transform failed.

derivative

public org.opengis.referencing.operation.Matrix derivative(Point2D point)
                                                    throws org.opengis.referencing.operation.TransformException

Gets the derivative of this transform at a point. This method delegates to the ConcatenatedTransform.derivative(DirectPosition) method because the transformation steps ConcatenatedTransform.transform1 and ConcatenatedTransform.transform2 may not be instances of MathTransform2D.

Specified by:

derivative in interface org.opengis.referencing.operation.MathTransform2D

Parameters:

point - the position where to evaluate the derivative.

Returns:

the derivative at the specified point as a 2×2 matrix.

Throws:

org.opengis.referencing.operation.TransformException - if the derivative cannot be evaluated at the specified point.

inverse

public org.opengis.referencing.operation.MathTransform2D inverse()
                                                          throws org.opengis.referencing.operation.NoninvertibleTransformException

Creates the inverse transform of this object.

Specified by:

inverse in interface org.opengis.referencing.operation.MathTransform

Specified by:

inverse in interface org.opengis.referencing.operation.MathTransform2D

Overrides:

inverse in class ConcatenatedTransform

Throws:

org.opengis.referencing.operation.NoninvertibleTransformException
