[Insight-users] pointer to image data

[Angobar]

Thanks for your reply J

 

What I want to do is to translate an image that is referenced with a doublé* pointer to a itk smartpointer. I think that the filter structure is not suitable for me in that case.

 

I have try this : ImageType::Pointer salida = ImageType::New();

                salida = reinterpret_cast<ImageType::Pointer> (out_inv);

 

But is not working, then I have try with a function that do this process:

 

 

void prueba_r01::double2itk( double* im_proc, ImageType::Pointer salida, int alto, int ancho)

{

                ImageType::IndexType pixelIndex;

                ImageType::PixelType pixelValue;

 

                for (int x=0; x<ancho; x++){

                               pixelIndex[0]=x;

                               for (int y=0; y<alto; y++){

                                               pixelIndex[1]=y;

                                               pixelValue= *(im_proc+x+ancho*y);

                                               salida->SetPixel(pixelIndex,pixelValue);

                               }

 

                }

}

 

But is giving me some problems in run-time….

 

Thanks for your help!!

Regards

Hello!

Sorry for the late reply but i am on holidays now so i check my emails not so often.
and i also do not have any examples here to show since i am in a another country.
but basically you can make this up for any filter. for example a very easy one
to compile is the recursivegaussian filter.
also i am just implementing itk functions to another application and i don't
think you will gain any insight about that applications preferences of how to 
make pointers to data. but what i have to do is:

1. create an image with correct size an pixel type
2. lock that data as continuous block
3. make a pointer with reinterpret_cast to that image's data
4. and then use the output of an itk filter as i wrote in that email.

Hope this helps!

Cheers,
toni

Sorry, I have a very similar problem just right now, what kind of object o what was the definition of "filter" for this case?
