| − | # Examples:
| |
| − | ## Use the SampleData module to load the MR Head volume. You can control the scalar display options using this module.
| |
| − | ## Use the SampleData module to download the DTI Head volume. A tensor-specific display interface will allow you to display a variety of scalar modes and display glyphs.

| |
| − | # When loading a 2D image(jpg, png, tiff ...), the window level(colors) might be skewed. To see the original colors switch the ''Window Level'' combobox to '''Manual Min/Max''', then set ''Min'' to '''0''' and ''Max'' to '''255'''.
| |
| − | ## Also use the Spacing field to enter the volumetric pixel sizes of the image data.
| |
| − | ## While you can display color volumes as slices, most slicer modules do not work natively with RGB or RGBA data, the new [http://slicer.org/doc/html/VectorToScalarVolume_8py_source.html VectorToScalarVolume] converter can be used to create a volume for use, for example, with the Editor. (added post-4.1).

| − | ===How to create a volume node from scratch? ===
| |
| − | You need to create a vtkImageData, a vtkMRMLScalarVolumeNode and a vtkMRMLScalarVolumeDisplayNode.
| |
| − | <pre>
| |
| − | vtkNew<vtkImageData> imageData;
| |
| − | imageData->SetScalarTypeToUnsignedChar();
| |
| − | imageData->SetNumberOfScalarComponents(1);
| |
| − | imageData->SetDimensions(10,10,10);
| |
| − | imageData->Allocate();
| |
| − | // initialize the pixels here.
| |
| − | | |
| − | vtkNew<vtkMRMLScalarVolumeNode> volumeNode;
| |
| − | volumeNode->SetAndObserveImageData(volume);
| |
| − | volumeNode->SetOrigin( -10., -10., -10.);
| |
| − | volumeNode->SetSpacing( 2., 2., 2. );
| |
| − | mrmlScene->AddNode( volumeNode.GetPointer() );
| |
| − | | |
| − | vtkNew<vtkMRMLScalarVolumeDisplayNode> displayNode;
| |
| − | mrmlScene->AddNode( displayNode.GetPointer() );
| |
| − | volumeNode->SetAndObserveDisplayNodeID(displayNode->GetID());
| |
| − | | |
| − | </pre>
| |
| − | Note that the origin and spacing must be set on the volume node instead of the image data.

| − | [[Documentation/{{documentation/version}}/SlicerApplication/SupportedDataFormat|Here]] is the list of supported file formats.
