| X11 Texture From PixmapX11 Texture From Pixmap — Functions for creating and manipulating 2D meta textures derived from X11 pixmaps. | 
These functions allow high-level meta textures (See the CoglMetaTexture interface) that derive their contents from an X11 pixmap.
CoglBool
cogl_is_texture_pixmap_x11 (void *object);
Checks whether object
 points to a CoglTexturePixmapX11 instance.
Since: 1.4
Stability Level: Unstable
CoglTexturePixmapX11 * cogl_texture_pixmap_x11_new (CoglContext *context,uint32_t pixmap,CoglBool automatic_updates,CoglError **error);
Creates a texture that contains the contents of pixmap
. If
automatic_updates
 is TRUE then Cogl will attempt to listen for
damage events on the pixmap and automatically update the texture
when it changes.
| context | ||
| pixmap | A X11 pixmap ID | |
| automatic_updates | Whether to automatically copy the contents of the pixmap to the texture. | |
| error | A CoglError for exceptions |

Stability Level: Unstable
void cogl_texture_pixmap_x11_update_area (CoglTexturePixmapX11 *texture,int x,int y,int width,int height);
Forces an update of the given texture
 so that it is refreshed with
the contents of the pixmap that was given to
cogl_texture_pixmap_x11_new().
| texture | A CoglTexturePixmapX11 instance | |
| x | x coordinate of the area to update | |
| y | y coordinate of the area to update | |
| width | width of the area to update | |
| height | height of the area to update |

CoglBool
cogl_texture_pixmap_x11_is_using_tfp_extension
                               (CoglTexturePixmapX11 *texture);
Checks whether the given texture
 is using the
GLX_EXT_texture_from_pixmap or similar extension to copy the
contents of the pixmap to the texture.  This extension is usually
implemented as zero-copy operation so it implies the updates are
working efficiently.
Since: 1.4
Stability Level: Unstable
void cogl_texture_pixmap_x11_set_damage_object (CoglTexturePixmapX11 *texture,uint32_t damage,CoglTexturePixmapX11ReportLevel report_level);
Sets the damage object that will be used to track automatic updates
to the texture
. Damage tracking can be disabled by passing 0 for
damage
. Otherwise this damage will replace the one used if TRUE
was passed for automatic_updates to cogl_texture_pixmap_x11_new().
Note that Cogl will subtract from the damage region as it processes damage events.
| texture | A CoglTexturePixmapX11 instance | |
| damage | A X11 Damage object or 0 | |
| report_level | The report level which describes how to interpret the damage events. This should match the level that the damage object was created with. |
