Hi!<br>
<br>
I am new to vtk.<br>
<br>
I am using the vtkImageImport class to view a non vtk object:<br>
<br>
importer->SetImportVoidPointer(&myAdapter->m_ImageISIS->voxel<short>(0,0,0,0));<br>
importer->SetWholeExtent(0,dimensions[0]-1,0,dimensions[1]-1,0,dimensions[2]-1);<br>
importer->SetDataExtentToWholeExtent();<br>
importer->SetDataScalarTypeToShort();<br>
importer->Update();<br>
viewer->SetInputConnection(importer->GetOutputPort());<br>
viewer->SetZSlice(100);<br>
viewer->Render();<br>
sleep(5);<br>
<br>
This works fine. The second thing i want to do is safe the data as a
vtk image and open it with paraview:<br>
<br>
vtkImageWriter* writer = vtkImageWriter::New();<br>
writer->SetFileDimensionality(3);<br>
writer->SetInputConnection(importer->GetOutputPort());<br>
writer->SetFileName("test.vtk");<br>
writer->UpdateWholeExtent();<br>
writer->Write();<br>
<br>
The file is safed, but i can not open it with paraview. There is always
a message: "a reader for ... could not be found. please choose one". <br>
And when i choose vtk image reader the message:<br>

appears.<br>
<br>
The third thing i want to do is store the data to a vtkImageData object.<br>
Is there any possibility to directly forward the vtkImageImport (or
pointer of the first element of the data array) to the vtkImageData, so
i do not have to do it voxel by voxel? Because this needs a lot of time
for big data.<br>
<br>
Thanks for your help!<br>
<br>
cheers<br>
