Description

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

You need to include <clutter/cex100/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

Since 1.6

enum ClutterCex100BufferingMode

typedef enum {
  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

Since 1.6

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

Since 1.6

clutter_cex100_get_egl_display ()

EGLDisplay          clutter_cex100_get_egl_display      (void);

Retrieves the EGL display used by Clutter, if it supports the EGL windowing system and if it is running using an EGL backend.

Returns :

the EGL display used by Clutter, or 0

Since 1.10
