<p>
<a class="link" href="GwyLayerMask.html" title="GwyLayerMask"><span class="type">GwyLayerMask</span></a> is a data view layer that can paint data as a color mask with
varying opacity. It is not normally usable outside a <a class="link" href="GwyDataView.html" title="GwyDataView"><span class="type">GwyDataView</span></a>.
</p>
<p>
The layer takes all infromation from its parent <a class="link" href="GwyDataView.html" title="GwyDataView"><span class="type">GwyDataView</span></a>, therefore you
do not set its properties directly, but you change them in the corresponding
<a href="../libgwyddion/GwyContainer.html"><span class="type">GwyContainer</span></a> and/or use methods like <a class="link" href="GwyLayerMask.html#gwy-layer-mask-set-color-key" title="gwy_layer_mask_set_color_key ()"><code class="function">gwy_layer_mask_set_color_key()</code></a> to
make the layer read a different value from the container.
