[Insight-developers] itkImageMapper & Tcl Wrapping

[Luis Ibanez]

Hi Brad,

The problem with the Tcl wrapping of the itk::ImageMapper
was related with a couple of default options in the template
parameters.


1) Affine transform is by defauld : 3D
   So the definition of AffineTransform<float> results in
   AffineTransform<float,3>. A mapper was being defined with 
   a 2D image and a 3D transform.

2) The affine transform was instatiated with <float> but the
   Interpolator that it is used by the mapper is by default 
   instantiated over <double>. That resulted in a mismatch
   between Point<double,3> and Point<float,3> in the Evaluate()
   method.

So, a "TransformDouble" == AffineTransform<double>  was added 
to Insight/Testing/Code/Algorithms/CMakeListsTcl.txt, and 
the ImageMapper was instantiated over: Image3D and TransformDouble.

With this changes, the ImageMapper wrapping is working under 
Linux 2.2.18 and gcc 2.95.2.



Additionally, a test for itkImageMapper was added under 
Insight/Code/Algorithms/itkImageMapperTest.cxx
