[vtkusers] vtkImageReslice problem...output parameters are reset???

[Mathieu Coursolle]

Hi, 
I have a vtkImageData representing a volume. I want to
display the image of a single slice.
However, once I set my volume to a vtkImageReslice, the
vtkImageReslice output parameters are not the same as its
input...in fact, the SetInput does not seem to have any effect...
Here is how I do it...
 
vtkImageData* volume = vtkImageData::New();
   volume->SetScalarTypeToFloat();
   volume->SetDimensions(74, 25, 8);
   volume->AllocateScalars();
   volume->SetSpacing(2, 2, 2.5);
   volume->SetOrigin(0, 0, 0);
 
float* data = (float*)(volume->GetScalarPointer());
memcpy(data, source_data; 74 * 25 * 8 * sizeof(float));
 
vtkImageReslice* slice = vtkImageSlice::New();
   slice->SetInput(volume);
 
int d1[3];
volume->GetDimensions(d);
int d2[3];
slice->GetOutput()->GetDimensions(d);
 
d should be the same in both cases rigth???
It is always good in the volume but 0 in the slice
output...Any idea why???
 
Your help would really be appreciated...
Thanx!
