generate isoline(s) from structured points set
<p>
<a class="el" href="a00989.html" title="generate isoline(s) from structured points set">vtkMarchingSquares</a> is a filter that takes as input a structured points set and generates on output one or more isolines. One or more contour values must be specified to generate the isolines. Alternatively, you can specify a min/max scalar range and the number of contours to generate a series of evenly spaced contour values.<p>
To generate contour lines the input data must be of topological dimension 2 (i.e., an image). If not, you can use the ImageRange ivar to select an image plane from an input volume. This avoids having to extract a plane first (using vtkExtractSubVolume). The filter deals with this by first trying to use the input data directly, and if not a 2D image, then uses the ImageRange ivar to reduce it to an image.<p>
<dl class="warning" compact><dt><b>Warning:</b></dt><dd>This filter is specialized to images. If you are interested in contouring other types of data, use the general <a class="el" href="a00323.html" title="generate isosurfaces/isolines from scalar values">vtkContourFilter</a>. </dd></dl>
