#include <sitkTransform.h>
A simplified wrapper around a variety of ITK transforms.
The interface to ITK transform objects to be used with the ImageRegistrationMethod, ResampleImageFilter and other SimpleITK process objects. The transforms are designed to have a serialized array of parameters to facilitate optimization for registration.
Provides a base class interface to any type of ITK transform. Objects of this type may have their interface converted to a derived interface while keeping the same reference to the ITK object.
Additionally, this class provides a basic interface to a composite transforms.

Construct a specific transformation.
- Deprecated:
- This constructor will be removed in future releases.
Use an image to construct a transform.
The input displacement image is transferred to the constructed transform object. The input image is modified to be a default constructed Image object.
Only the sitkDisplacementField transformation type can currently be constructed this way. Image must be of sitkVectorFloat64 pixel type with the number of components equal to the image dimension.

- This constructor will be removed in future releases.

Return a new inverse transform of the same type as this.
Creates a new transform object and tries to set the value to the inverse. As not all transform types have inverse and some transforms are not invertable, an exception will be throw is there is no inverse.
Get access to internal ITK data object.
The return value should imediately be assigned to as itk::SmartPointer.
In many cases the value may need to be dynamically casted to the the actual transform type.

Performs actually coping if needed to make object unique.
The Transform class by default performs lazy coping and assignment. This method make sure that coping actually happens to the itk::Transform pointed to is only pointed to by this object.

Performs a shallow copy of the internal ITK transform. A deep copy will be done if the transform in modified.

Try to change the current transform to it's inverse.
If the transform has an inverse, i.e. non-singular linear transforms, then a new ITK transform is created of the same type and this object is set to it.
However not all transform have a direct inverse, if the inverse does not exist or fails false will be returned and this transform will not be modified.
