Constructors/destructors for psPlaneTransform, psPlaneDistort

[Eric.VanAlst@…]

In SDR-02 paragraph 5.3.1, the data types psPlaneTransform and psPlaneDistor
are defined. Should there be constructors and destructors for these types
similar to psSphereTransform is section 5.3.2?

[eugene]

yes, there should be constructors & destructors.

the constructors needs to take the polynomial orders for each dimension.

[Eric.VanAlst@…]

The resolution specifies there should be constructors and destructors but this
functions are not present in SDR-06 section 5.3.1.

[Paul Price]

Added constructors to the SDRS. We don't specify destructors unless there's
something special that needs to be done, and in this case, there isn't.

Each of \code{psPlaneTransform} and \code{psPlaneDistort} has an
appropriate allocator that takes the polynomial order in each
dimension. Both the \code{x} and \code{y} polynomials shall be have
the same dimensions.
\begin{verbatim}
psPlaneTransform *psPlaneTransformAlloc(int n1, int n2);
psPlaneDistort *psPlaneDistortAlloc(int n1, int n2, int n3, int n4);
\end{verbatim}

[Paul Price]

Should be fixed in SDRS-07 and ADD-06 (7 September 2004).
