<p><a name="index-picture-box-384"></a><strong>Syntax:</strong>
<a name="index-picturebox-385"></a>
<pre class="example">     picturebox[<var>baseline</var>]
     picturebox[<var>baseline</var>] (<var>p1</var>)(<var>p2</var>)
</pre>
   <p class="noindent">The first form of <code>picturebox</code> causes a scalar <var>baseline</var>
fraction to be emitted in the <code>pspicture</code>
<a name="index-g_t_0040code_007bpspicture_007d-386"></a><a name="index-baseline-fraction-387"></a>environment of the output.  See
<code>PSTricks</code> documentation for <code>pspicture</code>.

   <p>In the second form, the <var>baseline</var> fraction is optional, and the
two points that follow define the diagonal of a three-dimensional
bounding box
<a name="index-bounding-box-388"></a>for the completed scene.  The parallel projection
<a name="index-parallel-projection-389"></a><a name="index-projection_002c-parallel-390"></a>of the bounding box
determines the corners of the drawing's <code>pspicture*</code> environment,
which is used in place of <code>pspicture</code>.  This causes PostScript to
clip
<a name="index-clipping-391"></a>the final drawing to the bounding box in 2d.  If there is a
<code>camera</code> specified, the camera tranformation is applied to the
bounding box, and the <code>pspicture</code> is set just large
enough to include the transformed box.

   <p>When no bounding box is given, <code>sketch</code> computes one
automatically.
