<a name="ClutterKeyframeTransition.description"></a><h2>Description</h2>
<p><a class="link" href="ClutterKeyframeTransition.html" title="ClutterKeyframeTransition"><span class="type">ClutterKeyframeTransition</span></a> allows animating a property by defining
"key frames": values at a normalized position on the transition
duration.</p>
<p>The <a class="link" href="ClutterKeyframeTransition.html" title="ClutterKeyframeTransition"><span class="type">ClutterKeyframeTransition</span></a> interpolates the value of the property
to which it's bound across these key values.</p>
<p>Setting up a <a class="link" href="ClutterKeyframeTransition.html" title="ClutterKeyframeTransition"><span class="type">ClutterKeyframeTransition</span></a> means providing the times,
values, and easing modes between these key frames, for instance:</p>
<div class="informalexample"><pre class="programlisting">
  ClutterTransition *keyframe;

  keyframe = clutter_keyframe_transition_new ("opacity");
  clutter_transition_set_from (keyframe, G_TYPE_UINT, 255);
  clutter_transition_set_to (keyframe, G_TYPE_UINT, 0);
  clutter_keyframe_transition_set (CLUTTER_KEYFRAME_TRANSITION (keyframe),
                                   G_TYPE_UINT,
                                   1, /* number of key frames */
                                   0.5, 128, CLUTTER_EASE_IN_OUT_CUBIC);
</pre></div>
<p></p>
<p>The example above sets up a keyframe transition for the <a class="link" href="ClutterActor.html#ClutterActor--opacity" title="The “opacity” property"><span class="type">“opacity”</span></a>
property of a <a class="link" href="ClutterActor.html" title="ClutterActor"><span class="type">ClutterActor</span></a>; the transition starts and sets the value of the
property to fully transparent; between the start of the transition and its mid
point, it will animate the property to half opacity, using an easy in/easy out
progress. Once the transition reaches the mid point, it will linearly fade the
actor out until it reaches the end of the transition.</p>
<p>The <a class="link" href="ClutterKeyframeTransition.html" title="ClutterKeyframeTransition"><span class="type">ClutterKeyframeTransition</span></a> will add an implicit key frame between the last
and the 1.0 value, to interpolate to the final value of the transition's
interval.</p>
<p><a class="link" href="ClutterKeyframeTransition.html" title="ClutterKeyframeTransition"><span class="type">ClutterKeyframeTransition</span></a> is available since Clutter 1.12.</p>
