Set the decoration state for a single signature in a PDF document. This function does not check whether the field exists. The decorations set by this function are ignored unless setDecorations(true) is in effect. #ds_auto will be assumed for all fields for which setDecorationState() has not been called. Any values set with this function will be ignored for rendering TIFF documents.
