## Synopsis

    void                clutter_cex100_set_plane            (gdl_plane_id_t plane);
    enum                ClutterCex100BufferingMode;

## Description

The CEX100 backend for Clutter provides some Intel CE3100/CE4100 specific API

You need to include `<clutter/egl/clutter-cex100.h>` to have access to the functions documented here.

## Details

### clutter_cex100_set_plane ()

    void                clutter_cex100_set_plane            (gdl_plane_id_t plane);

Intel CE3100 and CE4100 have several planes (frame buffers) and a hardware blender to blend the planes togeteher and produce the final image.

`clutter_cex100_set_plane()` let's you configure the GDL plane where the stage will be drawn. By default Clutter will pick UPP_C (GDL_PLANE_ID_UPP_C).

### Note

This function has to be called before `clutter_init()`

`plane` : | a GDL plane

### enum ClutterCex100BufferingMode

    typedef enum /*< prefix=CLUTTER_CEX100 >*/
    {
      CLUTTER_CEX100_DOUBLE_BUFFERING = 2,
      CLUTTER_CEX100_TRIPLE_BUFFERING = 3
    } ClutterCex100BufferingMode;

Enum passed to `clutter_cex100_set_buffering_mode()`.

`CLUTTER_CEX100_DOUBLE_BUFFERING` | The GDL plane will be double buffered
`CLUTTER_CEX100_TRIPLE_BUFFERING` | The GDL plane will be triple buffered

### clutter_cex100_set_buffering_mode ()

    void                clutter_cex100_set_buffering_mode   (ClutterCex100BufferingMode mode);

Configure the buffering mode of the underlying GDL plane. The GDL surface used by Clutter to draw can be backed up by either one or two back buffers thus being double or triple buffered, respectively.

Clutter defaults to `CLUTTER_CEX100_TRIPLE_BUFFERING`.

### Note

This function has to be called before `clutter_init()`

`mode` : | a ClutterCex100BufferingMode
