<h3>Description</h3>
<p>
Cine_Control module records all the movements of the objects displayed in the data viewer. In playback mode the movements are played with a set frame rate. Recorded is everything covering the data window, except the mouse pointer.
</p>
<h3>Inputs</h3>
<p>
<i><b>mode</b></i>
</p>
<p>
Parameter for playing the loop forward (mode=0) or backward (mode=1)
</p>
<p>
<i><b>rate</b></i>
</p>
<p>
Reference to the frame rate value, via the parameter block, which is referenced by the &CineParams input.
</p>
<p>
<i><b>start</b></i>
</p>
<p>
Defines the start frame (usually set to 0)
</p>
<p>
<i><b>end</b></i>
</p>
<p>
Defines the end frame. Used with CineInteract the end frame is set automatically. With CineLoop the end frame has to be set.
</p>
<p>
<i><b>run</b></i>
</p>
<p>
Reference to the capture value, via the parameter block, which is referenced by the &CineParams input.
</p>
<h3>Outputs</h3>
<p>
<i><b>value</b></i>
</p>
<p>
Value of the currently shown frame.
</p>
<h3>Utility Macros</h3>
<p>
The Cine_Control module is used in the Functional Macro CineFunc and is cooperating with the Image_cache module.
</p>
<h3>Example</h3>
<p>
An example application CineInteractEg and CineLoopEg is provided, which uses the AVS/Express sample data file mri.fld, to show the functionality of the macro.
</p>
<h3>Files</h3>
<p>
<I>iac_proj/cine/cine_mods.v</I> contains the CineParams group, the Image_Cache module and the Cine_Control module V definitions.
