[Insight-users] test image for DeformableRegistration7.cxx and DeformableRegistration8.cxx

[Luis Ibanez]

Hi Xavier,


Thanks for your clarification.


The reason why you cannot use BMP as file format for the resampled
images is that they are declared as using pixeltype = "signed short".


This pixel type is not supported by the BMP fileformat.


BTW, BMP is an extremely poor fileformat for medical images, you
may want to avoid it unless you are in a really desperate situation.


You may want to use Analyze or MetaImage in order to save the output
images, and MetaImage or VTK in order to save the deformation field.



    Regards,


       Luis
