[Insight-users] Create image types in run time

[Luis Ibanez]

Hi David,

Yes, the typical way of doing this is to write an Image class
that internally contains instantiation of all the image types
that you want to manage.

Then, you use Switch statements in order to pick the appropriate
type at run time.

For an example on how to do this,
please look at the Insight Journal paper:

     http://www.insight-journal.org/browse/publication/146

The paper includes the source code that manage multiple image types.


You will find the same source code in the InsightApplications
checkout, under the directory:

     InsightApplications/Auxiliary/vtk
         vtkKWImage.cxx
         vtkKWImage.h
         vtkKWImageIO.cxx
         vtkKWImageIO.h


Note that, this code is mostly intended to interface with VTK,
but it will still illustrate how to manage a set of different
image types at run time.


    Regards,


       Luis
