<h2>Description</h2>
<p>
Retrieves a previously stored snapshot (in memory), i.e. sets all valuator to the corresponding values stored in that snaphot.

<div class="refsect1" title="Initialization">
<a id="idp20812528"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>inumsnap</em></span> -- current number of snapshots.
</p>
<p>
<span class="emphasis"><em>index</em></span> -- a number referring unequivocally to a snapshot. Several snapshots can be stored in the same bank.
</p>
<p>
<span class="emphasis"><em>igroup</em></span> -- (optional) an integer number referring to a snapshot-related group of widget. It allows to get/set, or to load/save the state of a subset of valuators. Default value is zero that refers to the first group. The group number is determined by the opcode <a class="link" href="FLsetSnapGroup.html" title="FLsetSnapGroup"><em class="citetitle">FLsetSnapGroup</em></a>.

<h2>Performance</h2>
<p>
<span class="emphasis"><em>FLgetsnap</em></span> retrieves a previously stored snapshot (in memory), i.e. sets all valuator to the corresponding values stored in that snapshot. The <span class="emphasis"><em>index</em></span> argument unequivocally must refer to an already existing snapshot. If the <span class="emphasis"><em>index</em></span> argument refers to an empty snapshot or to a snapshot that doesn't exist, no action is done. <span class="emphasis"><em>FLsetsnap</em></span> outputs the current number of snapshots (<span class="emphasis"><em>inumsnap</em></span> argument).
</p>
<p>
For purposes of snapshot saving, widgets can be grouped, so that snapshots affect only a defined group of widgets. The opcode <a class="link" href="FLsetSnapGroup.html" title="FLsetSnapGroup"><em class="citetitle">FLsetSnapGroup</em></a> is used to specify the group for all widgets declared after it, until the next <a class="link" href="FLsetSnapGroup.html" title="FLsetSnapGroup"><em class="citetitle">FLsetSnapGroup</em></a> statement.
