41 /*! \brief Information associated with VGImage.
42 *
43 * A VGImage can associated one of pattern or surface. This type is
44 * used to make sure previous associated pattern or surface being
45 * released before new association.
46 *
47 * A _ge_openvg_img can be associated by mutltiple patterns and
48 * surfaces. But, at most one of associated patterns or surfaces, the
49 * _ge_openvg_img can be activated for at any instant.
50 * _ge_openvg_img::activated_for trace the object it being activated
51 * for. When a context will be current, the _ge_openvg_img associated
52 * with its surface would be activated for the surface. When a paint
53 * wil be used, the _ge_openvg_img associated must be activated for
54 * the paint. Before activated, the old activation must be
55 * deactivated. _ge_openvg_img::deactivate_func is a pointer to
56 * deactivation function of activated pattern or surface.
57 *
58 * \sa _ge_openvg_img_t
59 * \note This is type is for internal using of OpenVG graphic engine.
