Description
Returns the opacity value used to draw the visible appearance of an annotation (requires Acrobat 5 or higher).A value of 1 determines that the annotation is completely opaque. If the value is zero, newly created annotations will be invisible. The opacity flag is not supported by all annotation types.
At time of publication the opacity property is used for annotations only. Later versions of DynaPDF use this property may be for other PDF objects too.
