Method Details

inverse

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

Returns the inverse of this math transform.

Specified by:

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

Specified by:

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

Specified by:

inverse in class AbstractMathTransform2D.Inverse

Returns:

the inverse of this transform.

transform

public org.opengis.referencing.operation.Matrix transform(double[] srcPts,
 int srcOff,
 double[] dstPts,
 int dstOff,
 boolean derivate)
                                                   throws org.opengis.referencing.operation.TransformException

Inverse transforms the specified srcPts and stores the result in dstPts. If the derivative has been requested, then this method will delegate the derivative calculation to the enclosing class and inverts the resulting matrix.

Specified by:

transform in class AbstractMathTransform

Parameters:

srcPts - the array containing the source coordinates (cannot be null).

srcOff - the offset to the point to be transformed in the source array.

dstPts - the array into which the transformed coordinates is returned. May be the same than srcPts. May be null if only the derivative matrix is desired.

dstOff - the offset to the location of the transformed point that is stored in the destination array.

derivate - true for computing the derivative, or false if not needed.

Returns:

the matrix of the transform derivative at the given source position, or null if the derivate argument is false.

Throws:

org.opengis.referencing.operation.TransformException - if the point cannot be transformed or if a problem occurred while calculating the derivative.
