generate an image stencil
<p>
<a class="el" href="a00837.html" title="generate an image stencil">vtkImageStencilSource</a> is a superclass for filters that generate image stencils. Given a clipping object such as a <a class="el" href="a00855.html" title="abstract interface for implicit functions">vtkImplicitFunction</a>, it will set up a list of clipping extents for each x-row through the image data. The extents for each x-row can be retrieved via the GetNextExtent() method after the extent lists have been built with the BuildExtents() method. For large images, using clipping extents is much more memory efficient (and slightly more time-efficient) than building a mask. This class can be subclassed to allow clipping with objects other than <a class="el" href="a00855.html" title="abstract interface for implicit functions">vtkImplicitFunction</a>. <dl class="see" compact><dt><b>See also:</b></dt><dd><a class="el" href="a00855.html" title="abstract interface for implicit functions">vtkImplicitFunction</a> <a class="el" href="a00835.html" title="combine images via a cookie-cutter operation">vtkImageStencil</a> <a class="el" href="a01275.html" title="use polydata to mask an image">vtkPolyDataToImageStencil</a> </dd></dl>
