        SECTION 9.1                                                                 Multimedia



KEY   TYPE              VALUE

O     number            (Optional) A number in the range 0.0 to 1.0 specifying the constant opacity value to
                        be used in painting the background color specified by B. A value below 1.0 means
                        the window is transparent; for example, windows behind a floating window show
                        through if the media does not cover the entire floating window. A value of 0.0 indi-
                        cates full transparency and makes B irrelevant. Ignored for full-screen and hidden
                        windows.
                        Default value: 1.0 (fully opaque).

M     integer           (Optional) A monitor specifier (see Table 9.28) that specifies which monitor in a
                        multi-monitor system a floating or full-screen window should appear on. Ignored
                        for other types.
                        Default value: 0 (document monitor). Unrecognized value in MH: object is non-via-
                        ble; in BE: treat as default value.

F     dictionary        (Required if the value of W is 0; otherwise ignored) A floating window parameters
                        dictionary (see Table 9.19) specifying the size, position, and options used in dis-
                        playing floating windows.

        The F entry in the media screen parameters MH/BE dictionaries is a floating win-
        dow parameters dictionary, whose entries are listed in Table 9.19. The entries in
        the floating window parameters dictionary are treated as if they were present in
        the MH or BE dictionaries that they are referenced from. That is, the contained
        entries are individually evaluated for viability rather than the dictionary being
        evaluated as a whole. (There may be an F entry in both MH and BE. In such a case,
        if a given entry is present in both floating window parameters dictionaries, the
        one in the MH dictionary takes precedence.)

        The D, P, and RT entries are used to specify the rectangle that the floating window
        occupies. Once created, the floating window’s size and position are not tied to any
        other window, even if the initial size or position was computed relative to other
        windows.

        Unrecognized values for the R, P, RT, and O entries are handled as follows: if they
        are nested within an MH dictionary, the floating window parameters object (and
        hence the media screen parameters object) must be considered non-viable; if they
        are nested within a BE dictionary, they should be considered to have their default
        values.
