L.3.4.6 Conditional Properties

Another important aspect of time nodes is conditional properties. There are four such conditions:

Start Condition

Conditions that must be met for a time node to start.

Previous Condition

Conditions that must be met for a time node to go back to the previous time node.

Next Conditions

Conditions that must be met for a time node to advance to the next time node.

End Conditions

Conditions that must be met for a time node to end.

Conditional properties are useful for providing finer granularity as to exactly when a time node should be activated. For example, suppose we have a shape with an entrance appearance after five seconds. The stCondLst element should be used as follows:

<p:par>
  <p:cTn id="5">
    <p:stCondLst>
      <p:cond delay="5000"/>
    </p:stCondLst>
  </p:cTn>
</p:par>
