public: 
ApplyTransformationParametersCommand();

Example

This example computes the translation parameters. The example makes the assumption that you have saved the position of the registration marks of the reference image in a file. Modify this example and replace the manual assignment of the rmData with your own code to load the reference registration mark data before testing this example.
