Description

Details

cogl_check_extension ()

gboolean            cogl_check_extension                (const char *name,
                                                         const char *ext);

Warning

cogl_check_extension has been deprecated since version 1.2 and should not be used in newly-written code. OpenGL is an implementation detail for Cogl and so it's not appropriate to expose OpenGL extensions through the Cogl API. This function can be replaced by the following equivalent code:

1
gboolean retval = (strstr (ext, name) != NULL) ? TRUE : FALSE;

Check whether name occurs in list of extensions in ext.

name :

extension to check for

ext :

list of extensions

Returns :

TRUE if the extension occurs in the list, FALSE otherwise.

cogl_viewport ()

void                cogl_viewport                       (unsigned int width,
                                                         unsigned int height);

Warning

cogl_viewport has been deprecated since version 1.2 and should not be used in newly-written code. Use cogl_set_viewport() instead

Replace the current viewport with the given values.

width :

Width of the viewport

height :

Height of the viewport

Since 0.8.2


cogl_get_bitmasks ()

void                cogl_get_bitmasks                   (int *red,
                                                         int *green,
                                                         int *blue,
                                                         int *alpha);

Gets the number of bitplanes used for each of the color components in the color buffer. Pass NULL for any of the arguments if the value is not required.

red :

Return location for the number of red bits or NULL. [out]

green :

Return location for the number of green bits or NULL. [out]

blue :

Return location for the number of blue bits or NULL. [out]

alpha :

Return location for the number of alpha bits or NULL. [out]

cogl_set_depth_test_enabled ()

void                cogl_set_depth_test_enabled         (gboolean setting);

Warning

cogl_set_depth_test_enabled has been deprecated since version 1.4 and should not be used in newly-written code. Use cogl_material_set_depth_test_enabled() instead.

Sets whether depth testing is enabled. If it is disabled then the order that actors are layered on the screen depends solely on the order specified using clutter_actor_raise() and clutter_actor_lower(), otherwise it will also take into account the actor's depth. Depth testing is disabled by default.

setting :

TRUE to enable depth testing or FALSE to disable.

cogl_get_depth_test_enabled ()

gboolean            cogl_get_depth_test_enabled         (void);

Warning

cogl_get_depth_test_enabled has been deprecated since version 1.4 and should not be used in newly-written code. Use cogl_material_get_depth_test_enabled() instead.

Queries if depth testing has been enabled via cogl_set_depth_test_enable()

Returns :

TRUE if depth testing is enabled, and FALSE otherwise
