- * @brief An Image object represents an image resource that can be added to ImageActors.
+ * @DEPRECATED_1_2.41
*
- * Image objects can be shared between ImageActors. This is practical if you have a visual element on screen
- * which is repeatedly used. An example would be a button background image.
- * The image resource is discarded when all ImageActors using the Image object are discarded or in case they
- * were created with ReleasePolicy::Unused, taken off stage.
- * Note: if a resource was shared between Image objects it exists until its last reference is gone.
+ * @brief An Image object represents an image resource that can be used for rendering.
*
- * Image objects are responsible for the underlying resource's lifetime.
+ * Image objects can be shared between Actors. This is practical if you have a visual element on screen
+ * which is repeatedly used.
*
- * <i>ReleasePolicies</i>
- * - Unused: release resource once ImageActor using it is taken off stage.
- * - Never: keep resource alive until Image object is thrown away.
+ * The image resource is released as soon as the last Image handle is released.
+ * @SINCE_1_0.0
+ * @note If a resource was shared between Image objects it exists until its last reference is gone.
*
- * <i>Resolution of conflicting policies</i>
- * If the same image is created more than once with conflicting policies, ReleasePolicy "Never" overrides "Unused".
+ * Image objects are responsible for the underlying resource's lifetime.
