ApplyTransformationParametersCommand Constructor()

Summary

Initializes a new ApplyTransformationParametersCommand class object with default parameters.

Syntax

Java

Objective-C

C++

public ApplyTransformationParametersCommand()

Public Function New()

- (instancetype)init

public ApplyTransformationParametersCommand()

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.
