Generic image filter with one input.
<p>
<a class="el" href="a01551.html" title="Generic image filter with one input.">vtkSimpleImageToImageFilter</a> is a filter which aims to avoid much of the complexity associated with <a class="el" href="a00727.html" title="Generic algorithm superclass for image algs.">vtkImageAlgorithm</a> (i.e. support for pieces, multi-threaded operation). If you need to write a simple image-image filter which operates on the whole input, use this as the superclass. The subclass has to provide only an execute method which takes input and output as arguments. Memory allocation is handled in <a class="el" href="a01551.html" title="Generic image filter with one input.">vtkSimpleImageToImageFilter</a>. Also, you are guaranteed to have a valid input in the Execute(input, output) method. By default, this filter requests it's input's whole extent and copies the input's information (spacing, whole extent etc...) to the output. If the output's setup is different (for example, if it performs some sort of sub-sampling), ExecuteInformation has to be overwritten. As an example of how this can be done, you can look at vtkImageShrink3D::ExecuteInformation. For a complete example which uses templates to support generic data types, see <a class="el" href="a01551.html" title="Generic image filter with one input.">vtkSimpleImageToImageFilter</a>.<p>
