typedef struct _MxTextureCache MxTextureCache;
The contents of this structure are private and should only be accessed through the public API.
typedef struct { GObjectClass parent_class; void (* loaded) (MxTextureCache *self, const gchar *uri, ClutterTexture *texture); void (* error_loading) (MxTextureCache *self, GError *error); /* padding for future expansion */ void (*_padding_0) (void); void (*_padding_1) (void); void (*_padding_2) (void); void (*_padding_3) (void); void (*_padding_4) (void); } MxTextureCacheClass;
MxTextureCache * mx_texture_cache_get_default (void
);
Returns the default texture cache. This is owned by Mx and should not be unreferenced or freed.
Returns : |
a MxTextureCache. [transfer none] |
ClutterTexture * mx_texture_cache_get_texture (MxTextureCache *self
,const gchar *uri
);
Create a new ClutterTexture with the specified image. Adds the image to the cache if the image had not been previously loaded. Subsequent calls with the same image URI/path will return a new ClutterTexture with the previously loaded image.
|
A MxTextureCache |
|
A URI or path to a image file |
Returns : |
a newly created ClutterTexture. [transfer none] |
ClutterActor * mx_texture_cache_get_actor (MxTextureCache *self
,const gchar *uri
);
This is a wrapper around mx_texture_cache_get_texture()
which returns
a ClutterActor.
|
A MxTextureCache |
|
A URI or path to a image file |
Returns : |
a newly created ClutterTexture. [transfer none] |
gboolean mx_texture_cache_contains (MxTextureCache *self
,const gchar *uri
);
Checks whether the given URI/path is contained within the texture cache.
|
A MxTextureCache |
|
A URI or path to an image file |
Returns : |
TRUE if the image exists, FALSE otherwise |
Since 1.2
void mx_texture_cache_insert (MxTextureCache *self
,const gchar *uri
,CoglHandle *texture
);
Inserts a texture into the texture cache. This can be useful if you want to cache a texture from a custom or unhandled URI type, or you want to override a particular texture.
If the image is already in the cache, this texture will replace it. A reference will be taken on the given texture.
|
A MxTextureCache |
|
A URI or local file path |
|
A CoglHandle to a texture |
Since 1.2
CoglHandle mx_texture_cache_get_cogl_texture (MxTextureCache *self
,const gchar *uri
);
Create a CoglHandle representing a texture of the specified image. Adds the image to the cache if the image had not been previously loaded. Subsequent calls with the same image URI/path will return the CoglHandle of the previously loaded image with an increased reference count.
|
A MxTextureCache |
|
A URI or path to an image file |
Returns : |
a CoglHandle to the cached texture. [transfer none] |
gint mx_texture_cache_get_size (MxTextureCache *self
);
Returns the number of items in the texture cache
|
A MxTextureCache |
Returns : |
the current size of the cache |
void mx_texture_cache_load_cache (MxTextureCache *self
,const char *filename
);
gboolean mx_texture_cache_contains_meta (MxTextureCache *self
,const gchar *uri
,gpointer ident
);
Checks whether there are any textures associated with the given URI by the given identifier.
|
A MxTextureCache |
|
A URI or path to an image file |
|
A unique identifier |
Returns : |
TRUE if the data exists, FALSE otherwise |
Since 1.2
CoglHandle mx_texture_cache_get_meta_cogl_texture (MxTextureCache *self
,const gchar *uri
,gpointer ident
);
Retrieves the CoglHandle of the previously added image associated with the given unique identifier.
See mx_texture_cache_insert_meta()
|
A MxTextureCache |
|
A URI or path to an image file |
|
A unique identifier |
Returns : |
A CoglHandle to a texture, with an added
reference. NULL if no image was found. [transfer full]
|
Since 1.2
ClutterTexture * mx_texture_cache_get_meta_texture (MxTextureCache *self
,const gchar *uri
,gpointer ident
);
Create a new ClutterTexture using the previously added image associated with the given unique identifier.
See mx_texture_cache_insert_meta()
|
A MxTextureCache |
|
A URI or path to an image file |
|
A unique identifier |
Returns : |
A newly allocated ClutterTexture, or
NULL if no image was found. [transfer full]
|
Since 1.2
void mx_texture_cache_insert_meta (MxTextureCache *self
,const gchar *uri
,gpointer ident
,CoglHandle *texture
,GDestroyNotify destroy_func
);
Inserts a texture that's associated with a URI into the cache. If the metadata already exists for this URI, it will be replaced.
This is useful if you have a widely used modification of an image, for example, an image with a border composited around it.
|
A MxTextureCache |
|
A URI or local file path |
|
A unique identifier |
|
A CoglHandle to a texture |
|
An optional destruction function for ident
