st_texture_cache_get_default ()

StTextureCache *
st_texture_cache_get_default (void);

st_texture_cache_load_sliced_image ()

ClutterActor *
st_texture_cache_load_sliced_image (StTextureCache *cache,
                                    GFile *file,
                                    gint grid_width,
                                    gint grid_height,
                                    gint scale,
                                    GFunc load_callback,
                                    gpointer user_data);

This function reads a single image file which contains multiple images internally. The image file will be divided using grid_width and grid_height ; note that the dimensions of the image loaded from path should be a multiple of the specified grid dimensions.

st_texture_cache_bind_cairo_surface_property ()

ClutterActor *
st_texture_cache_bind_cairo_surface_property
                               (StTextureCache *cache,
                                GObject *object,
                                const char *property_name);

Create a ClutterTexture which tracks the cairo_surface_t value of a GObject property named by property_name . Unlike other methods in StTextureCache, the underlying CoglTexture is not shared by default with other invocations to this method.

If the source object is destroyed, the texture will continue to show the last value of the property.

st_texture_cache_load_gicon ()

ClutterActor *
st_texture_cache_load_gicon (StTextureCache *cache,
                             StThemeNode *theme_node,
                             GIcon *icon,
                             gint size,
                             gint scale);

This method returns a new ClutterActor for a given GIcon. If the icon isn't loaded already, the texture will be filled asynchronously.

st_texture_cache_load_file_async ()

ClutterActor *
st_texture_cache_load_file_async (StTextureCache *cache,
                                  GFile *file,
                                  int available_width,
                                  int available_height,
                                  int scale);

Asynchronously load an image. Initially, the returned texture will have a natural size of zero. At some later point, either the image will be loaded successfully and at that point size will be negotiated, or upon an error, no image will be set.

st_texture_cache_load_file_to_cogl_texture ()

CoglTexture *
st_texture_cache_load_file_to_cogl_texture
                               (StTextureCache *cache,
                                GFile *file,
                                gint scale);

This function synchronously loads the given file path into a COGL texture. On error, a warning is emitted and NULL is returned.

st_texture_cache_load_file_to_cairo_surface ()

cairo_surface_t *
st_texture_cache_load_file_to_cairo_surface
                               (StTextureCache *cache,
                                GFile *file,
                                gint scale);

This function synchronously loads the given file path into a cairo surface. On error, a warning is emitted and NULL is returned.

StTextureCacheLoader ()

CoglTexture *
(*StTextureCacheLoader) (StTextureCache *cache,
                         const char *key,
                         void *data,
                         GError **error);

See st_texture_cache_load(). Implementations should return a texture handle for the given key, or set error .

st_texture_cache_load ()

CoglTexture *
st_texture_cache_load (StTextureCache *cache,
                       const char *key,
                       StTextureCachePolicy policy,
                       StTextureCacheLoader load,
                       void *data,
                       GError **error);

Load an arbitrary texture, caching it. The string chosen for key should be of the form "type-prefix:type-uuid". For example, "url:file:///usr/share/icons/hicolor/48x48/apps/firefox.png", or "stock-icon:gtk-ok".
