dumpdhgr -- Dump a Double-Hires Picture (1.2) : external command / by
            Jeff Hansen

syntax:  dumpdhgr pathname [-n]

ex:      dumpdhgr /picture/dhirespic -i<ctrl-I>H
         dumpdhgr /hard1/graphics/piechart.pic -n
         dumpdhgr /doublepic/=:fot

Dumpdhgr will dump a double-hires picture to the printer specified in your
Davex configuration file.  ProDOS filetypes BIN and FOT are allowed, and
the file is checked for size (number of blocks) to determine a valid
picture file.  The picture is diplayed on the screen, and will be inversed
as printing progresses.  A wildcard pathname is allowed--use at your own
discression.

options:

-n   Printer picture in 'normal' format.  The default is 'inverse', i.e.
     black dots on the screen are printed black on the printer.  'Normal'
     is just the opposite, white dots print as black.

-i   Printer card initialization string.  This string should be the code that
     your interface uses to enable printing of the high (8th) bit (necessary
     for graphics printing).  Consult your manual for the proper codes.  It
     will usually be in the form of "ctrl-I <char>".  Use the override feature
     of the Davex command line to enter control characters (type ctrl-O, then
     ctrl-I).  The default is "ctrl-I H", which works on Grappler interfaces.
