COMMAND NAME:

        INSTAPLOT

        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 not to 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 is that a large quantity 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
on machine gonzo}

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;
however, 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
which is 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.
