[Insight-users] ManagedITK + vtkdotnet

[Dan Mueller]

Hi Dário,

At the moment, itkVTKImageExport is not wrapped in ManagedITK, but you
should still be able to use vtkImageImport to import an image (below
example in C#):

// Read image using ITK
const uint dim = 3;
itk.itkPixelType pixel = itk.itkPixelType.UC;
itk.itkImage input = itk.itkImage.New(pixel, dim);
input.Read("C:/Temp/engine.mhd");

// Import image to VTK
vtk.vtkImageImport import = new vtk.vtkImageImport();
import.SetImportVoidPointer(input.Buffer);
import.SetDataScalarTypeToUnsignedChar();
import.SetNumberOfScalarComponents((int)input.PixelType.NumberOfComponentsPerPixel);
import.SetDataExtent(0, input.Size[0], 0, input.Size[1], 0, input.Size[2]);
import.SetDataSpacing(input.Spacing.Data);
import.SetDataOrigin(input.Origin.Data);
import.Update();

If you need the update requests to be propagated between the ITK and
VTK pipelines, then you will need to wrap itkVTKImageExport. I don't
have the time to do this at the moment, but let me know if you really
need this and I can give you some good pointers for how to get started
with a ManagedITK external project to make it happen.

Hope this helps,

Cheers, Dan
