<h1>ALE Exclusion Regions</h1>
|
|
|
|
<p>ALE offers exclusion regions as a way to disallow certain areas from being
|
|
used in alignment and (optionally) rendering. Spatial coordinates are
|
|
expressed in the rendering coordinate system (prior to scaling). In cases
|
|
where the default transformation is used with the original frame, this is
|
|
identical to the unscaled original frame coordinate system, taking the
|
|
upper-left corner to be (0, 0). Frame numbering begins with 0, which represents
|
|
the original frame.
|
|
|
|
<p>All specified volumes are excluded from alignment (except where they affect
|
|
the alignment reference image), and are excluded from rendering by default.
|
|
(See the <a href="../rendering/chains/">rendering chains</a> page for
|
|
information on how to ignore exclusion regions.) Exclusion region syntax is
|
|
as follows:
|
|
|
|
<pre>
|
|
--ex <args> Exclude a specified volume.
|
|
<args> are space-delimited horizontal,
|
|
vertical, and frame limits:
|
|
<xmin> <xmax> <ymin> <ymax> <fmin> <fmax>
|
|
</pre>
