The AccessibleGraphicShape service is implemented by the
graphic object shapes shapes com.sun.star.drawing.GraphicObjectShape and
com.sun.star.presentation.GraphicObjectShape.
The support of the ::drafts::com::sun::star::accessibility::XAccessibleImage interface
requires the shape to provide a description of the displayed image
and the image's size in the screen coordinate system (pixel). At
the time being this interface does not provide information that is
not available through the AccessibleShape service:
the size returned by the
::drafts::com::sun::star::accessibility::XAccessibleImage::getWidth and ::drafts::com::sun::star::accessibility::XAccessibleImage::getHeight functions is the same as that
returned by the ::drafts::com::sun::star::accessibility::XAccessibleComponent::getSize function; the description
returned by ::drafts::com::sun::star::accessibility::XAccessibleImage::getAccessibleImageDescription function
is the same as the one returned by the ::drafts::com::sun::star::accessibility::XAccessibleContext::getAccessibleDescription function.
This makes the additional interface for
the time being basically an indicator of graphic shapes. This may
change in the future.
