Examples of org.opengis.referencing.operation.MathTransform.transform()

org.opengis.referencing.operation.MathTransform.transform()
Transforms the specified {@code ptSrc} and stores the result in{@code ptDst}. If {@code ptDst} is {@code null}, a new {@link DirectPosition} object is allocated and then the result of thetransformation is stored in this object. In either case, {@code ptDst}, which contains the transformed point, is returned for convenience. If {@code ptSrc} and {@code ptDst} are the same object,the input point is correctly overwritten with the transformed point. @param ptSrc the specified coordinate point to be transformed. @param ptDst the specified coordinate point that stores the result of transforming{@code ptSrc}, or {@code null}. @return the coordinate point after transforming {@code ptSrc} and storing the resultin {@code ptDst}, or a newly created point if {@code ptDst} was null. @throws MismatchedDimensionException if {@code ptSrc} or{@code ptDst} doesn't have the expected dimension. @throws TransformException if the point can't be transformed.
