<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkImageAlgorithm is a filter superclass that hides much of the pipeline complexity. It handles breaking the pipeline execution into smaller extents so that the vtkImageData limits are observed. It also provides support for multithreading. If you don't need any of this functionality, consider using vtkSimpleImageToImageFilter instead. .SECTION See also vtkSimpleImageToImageFilter</p>
<p>To create an instance of class vtkImageAlgorithm, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkImageAlgorithm
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkImageAlgorithm has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, <code>obj</code> is an instance of the vtkImageAlgorithm class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>
<code>int = obj.IsA (string name)</code> </li>
<li>
<code>vtkImageAlgorithm = obj.NewInstance ()</code> </li>
<li>
<code>vtkImageAlgorithm = obj.SafeDownCast (vtkObject o)</code> </li>
<li>
<code>vtkImageData = obj.GetOutput ()</code> - Get the output data object for a port on this algorithm. </li>
<li>
<code>vtkImageData = obj.GetOutput (int )</code> - Get the output data object for a port on this algorithm. </li>
<li>
<code>obj.SetOutput (vtkDataObject d)</code> - Get the output data object for a port on this algorithm. </li>
<li>
<code>obj.SetInput (vtkDataObject )</code> - Set an input of this algorithm. You should not override these methods because they are not the only way to connect a pipeline. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::SetInputConnection(). These methods transform the input index to the input port index, not an index of a connection within a single port. </li>
<li>
<code>obj.SetInput (int , vtkDataObject )</code> - Set an input of this algorithm. You should not override these methods because they are not the only way to connect a pipeline. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::SetInputConnection(). These methods transform the input index to the input port index, not an index of a connection within a single port. </li>
<li>
<code>vtkDataObject = obj.GetInput (int port)</code> </li>
<li>
<code>vtkDataObject = obj.GetInput ()</code> </li>
<li>
<code>vtkImageData = obj.GetImageDataInput (int port)</code> </li>
<li>
<code>obj.AddInput (vtkDataObject )</code> - Add an input of this algorithm. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::AddInputConnection(). See SetInput() for details. </li>
<li>
<code>obj.AddInput (int , vtkDataObject )</code> - Add an input of this algorithm. Note that these methods support old-style pipeline connections. When writing new code you should use the more general vtkAlgorithm::AddInputConnection(). See SetInput() for details. </li>
