<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkImplicitFunctionToImageStencil will convert a vtkImplicitFunction into a stencil that can be used with vtkImageStencil or with other classes that apply a stencil to an image.</p>
<p>To create an instance of class vtkImplicitFunctionToImageStencil, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkImplicitFunctionToImageStencil
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkImplicitFunctionToImageStencil 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 vtkImplicitFunctionToImageStencil class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>
<code>int = obj.IsA (string name)</code> </li>
<li>
<code>vtkImplicitFunctionToImageStencil = obj.NewInstance ()</code> </li>
<li>
<code>vtkImplicitFunctionToImageStencil = obj.SafeDownCast (vtkObject o)</code> </li>
<li>
<code>obj.SetInput (vtkImplicitFunction )</code> - Specify the implicit function to convert into a stencil. </li>
<li>
<code>vtkImplicitFunction = obj.GetInput ()</code> - Specify the implicit function to convert into a stencil. </li>
<li>
<code>obj.SetInformationInput (vtkImageData )</code> - Set a vtkImageData that has the Spacing, Origin, and WholeExtent that will be used for the stencil. This input should be set to the image that you wish to apply the stencil to. If you use this method, then any values set with the SetOutputSpacing, SetOutputOrigin, and SetOutputWholeExtent methods will be ignored. </li>
<li>
<code>vtkImageData = obj.GetInformationInput ()</code> - Set a vtkImageData that has the Spacing, Origin, and WholeExtent that will be used for the stencil. This input should be set to the image that you wish to apply the stencil to. If you use this method, then any values set with the SetOutputSpacing, SetOutputOrigin, and SetOutputWholeExtent methods will be ignored. </li>
<li>
<code>obj.SetOutputOrigin (double , double , double )</code> - Set the Origin to be used for the stencil. It should be set to the Origin of the image you intend to apply the stencil to. The default value is (0,0,0). </li>
<li>
<code>obj.SetOutputOrigin (double a[3])</code> - Set the Origin to be used for the stencil. It should be set to the Origin of the image you intend to apply the stencil to. The default value is (0,0,0). </li>
<li>
<code>double = obj. GetOutputOrigin ()</code> - Set the Origin to be used for the stencil. It should be set to the Origin of the image you intend to apply the stencil to. The default value is (0,0,0). </li>
<li>
<code>obj.SetOutputSpacing (double , double , double )</code> - Set the Spacing to be used for the stencil. It should be set to the Spacing of the image you intend to apply the stencil to. The default value is (1,1,1) </li>
<li>
<code>obj.SetOutputSpacing (double a[3])</code> - Set the Spacing to be used for the stencil. It should be set to the Spacing of the image you intend to apply the stencil to. The default value is (1,1,1) </li>
<li>
<code>double = obj. GetOutputSpacing ()</code> - Set the Spacing to be used for the stencil. It should be set to the Spacing of the image you intend to apply the stencil to. The default value is (1,1,1) </li>
<li>
<code>obj.SetOutputWholeExtent (int , int , int , int , int , int )</code> - Set the whole extent for the stencil (anything outside this extent will be considered to be "outside" the stencil). If this is not set, then the stencil will always use the requested UpdateExtent as the stencil extent. </li>
<li>
<code>obj.SetOutputWholeExtent (int a[6])</code> - Set the whole extent for the stencil (anything outside this extent will be considered to be "outside" the stencil). If this is not set, then the stencil will always use the requested UpdateExtent as the stencil extent. </li>
<li>
<code>int = obj. GetOutputWholeExtent ()</code> - Set the whole extent for the stencil (anything outside this extent will be considered to be "outside" the stencil). If this is not set, then the stencil will always use the requested UpdateExtent as the stencil extent. </li>
<li>
<code>obj.SetThreshold (double )</code> - Set the threshold value for the implicit function. </li>
<li>
<code>double = obj.GetThreshold ()</code> - Set the threshold value for the implicit function. </li>
</ul>
