COMMAND NAME:

        INSTAPLOT

        Writes an image of the workstation screen to a file named
        "vw.spool", which can then be plotted on an 11 inch black and white
        Versatec electrostatic plotter using Valid's proprietary spoolers.
        Black pixels on the screen become black dots on the plot.
        White pixels on the screen become white dots on the plot.
        While generating the plot on Sun systems, the screen
        is frozen, the (mouse) cursor disappears and user input is
        suspended until the screen image is processed.


USAGE:
        INSTAPLOT DATE INVERSE FAST
OPTIONS:

        INSTAPLOT accepts the following options:

        INVERSE:
        Inverts the output so black becomes white and vice versa.

        DATE:
        Prints out a banner indicating the date and time of the instaplot.
        The default is to not print the date banner.

        FAST:
        Saves the screen memory in virtual space first, allowing the user
        to interact with the window system before the plot is complete.
        The disadvantage to this is that lots of virtual memory is consumed
        (> 1Meg) when doing this (not recommended).

        The options may occur in any order.  Omitting the options
        causes a default plot to be generated.

EXAMPLES:

        > INSTAPLOT
        > INSTAPLOT INVERSE
        > INSTAPLOT DATE
        > SYSTEM "rsh gonzo lpr -Pvplot < vw.spool" {spool the plot}

ADDITIONAL INFORMATION:

        On Sun-3/110 displays, use of the overlay planes slows the
        rasterizing process considerably.  This usage of the overlay
        planes is the default for "suntools" on Sun-3/110 displays.
        Using the "-8bit_color_only" argument to "suntools" will prevent
        this; but Sun notes that using the color planes for certain
        window objects will cause slower graphics/text speed in them.

        The black/white color is determined by the colormap visible at
        the time of the instaplot.  This is usually dependent on the
        position of the mouse cursor.

        Since the output is only black and white, some color combinations
        will be indistinguishable on the plot.
