[vtkusers] vtkImageActor error

[shivanna.prashanth at wipro.com]

Hi all,
  I am trying to set input to vtkImageActor from vtkImageReslice output
as shown below

     vtkImageReslice *axial=vtkImageReslice::New();
    axial->SetInput(vtkImgRdr->GetOutput());
    axial->SetOutputDimensionality(2);
    axial->SetInterpolationModeToCubic();
    axial->SetResliceAxesDirectionCosines(1, 0, 0,
        0, 1, 0,
        0, 0, 1);

    axial->Update();
   
    vtkImageActor *axial_actor = vtkImageActor::New();
    axial_actor->SetInput(axial->GetOutput());

When above code is executed I get the following errors at run time.

ERROR: In C:\martink\vtk42\VTK\Rendering\vtkImageActor.cxx, line 159
vtkOpenGLImageActor (0x05463DF8): This filter requires unsigned char
scalars as input

ERROR: In C:\martink\vtk42\VTK\Rendering\vtkImageActor.cxx, line 159

Can any one suggest me a solution for the above problem.


Thanks & Regards
Prashanth
