The function <code class="function">lqr_carver_get_ref_height</code> returns the internal reference
height of the image contained in the <code class="classname">LqrCarver</code> object pointed to by
<em class="parameter"><code>carver</code></em>, in pixel units.
</p><p>
The reference height is set as the original height at carver initialization, and reset any time
the carver gets subsequently flattened, either explicitly through <a class="xref" href="ref-lqr-carver-flatten.html" title="lqr_carver_flatten"><span class="refentrytitle"><code class="function">lqr_carver_flatten</code></span>(3)</a> or implicitly when the rescale direction changes or
an enlargment beyond the maximum enlargement step is performed.
