       dxprint - Capture and print screen image.

       dxprint [ flags ] [ file ]

       The  dxprint  (Print  Screen)  program allows you to capture the screen
       image in printable form.

       The available output formats are PostScript, Sixel, and	DDIF  (Digital
       Document Interchange Format).

       An  optional  time  delay  gives	 you  time  to rearrange the screen to
       iconify or restack windows, or to give focus to	the  window  with  the
       color map to be used for the capture.

       Output is sent to the standard output unless file is supplied.

       The  -X	option	displays  the  dxprint Graphical User Interface (GUI).
       This reference page describes the dxprint command line  interface.  Use
       the GUI help facility for help with the dxprint GUI.

       Consult the usage diagrams, above, to determine	what  combinations  of
       flags are permissible.

   Flags Specifying GUI and Time Delay
       Brings  up  the	dxprint	 graphical  user  interface from which you can
       invoke help for more information.  Causes a  wait  of  integer  seconds
       before the actual capture occurs, so that the screen arrangement can be
       changed prior to the capture. If deleted, no delay will occur.

   Flags Specifying Area to Capture
       Specify all four of the following options for a partial capture.	 Spec‐
       ify  none  of  the  options  for	 a  full screen capture.  There are no
       default values for these options.  Defines the upper left corner of the
       capture	region	in pixel units from the left edge of the screen active
       area.  Defines the upper left corner of the  capture  region  in	 pixel
       units  from  the top edge of the screen active area.  Defines the lower
       right corner of the capture region in pixel units from the left edge of
       the  capture  region  (in  other	 words, its width).  Defines the lower
       right corner of the capture region in pixel units from the top edge  of
       the capture region (in other words, its height).

   Flags Specifying Output File Format
       If no output-specifying flags are used, the default is -pf (PostScript,
       rotated/scaled to fit page).

       PostScript is the only output format that is by	default	 sent  to  the
       standard output. DDIF and Sixel formats are binary and must be saved to
       a file, with a command such as:

       dxprint -s file

       Creates the output file in Sixel format. A Sixel file can be viewed  in
       a  DECterm by using the cat command, or it can be printed on most types
       of printers from Digital Equipment Corporation.	Default.  Creates  the
       output  file  in	 PostScript  format.   Creates the output file in DDIF
       (CDA)  format.  A  DDIF	file  can  be  viewed  with  the  CDA	viewer
       (/usr/bin/X11/dxvdoc)  and  edited  with	 the  DECwindows bitmap editor

       The following three switches modify the output file when used according
       to the usage diagrams above.  Creates a (Sixel only) output file with a
       horizontal doubling of the printable output.  This is useful to	elimi‐
       nate a “squeezed” appearance of the screen image when printed on print‐
       ers that have a greater horizontal resolution than vertical resolution,
       such  as	 the  Digital LA50.  Creates an output file with a reversal of
       light and dark.	This option is useful to save  printer	ink  or	 toner
       when  printing  screen  images that are mostly dark.  Creates an output
       file that is either printed at a 90 degree angle, or uniformly  reduced
       in size, or both, so that it will fit entirely within an A-size printed
       page.  This option is implied when PostScript is chosen by default  (by
       omitting	 the -s, -p, and -D flags).  For Sixel captures, specifies the
       Sixel output device.  Integer represents a printer from	the  following

	   VT terminal or DECterm		 2
	   LA50					12
	   LA75					13
	   LA100				14
	   Laser printer (LN03, LPS20, etc.)	15
	   LCG01				19
	   LJ250 (256 color mode)		20
	   LA210				21
	   LJ250 (8 color mode)			24
       The default for black and white (-b) and greyscale (-G) screen captures
       is the LN03. The default for color captures (-c) is the LJ250.

   Flags Specifying Output Color
       Default.	 Creates a black and white capture file.   This	 rendering  is
       supported by all workstations and printers.  It will create a high con‐
       trast printed output - screen areas darker than 50%  gray  will	appear
       black,  and  lighter  screen  areas will appear white.  Creates a gray-
       scale capture file.  This rendering is supported by all	printers,  but
       only by color or gray-scale workstations.  A color screen image will be
       represented in the file by suitable shades of gray, but	there  may  be
       adjacent	 regions of different colors that coincidentally have the same
       gray value when printed and thus will “blend into” each other.  Creates
       a  color capture file.  This color rendering is supported by all print‐
       ers but only on color workstations (with any number of  color  planes).
       Printing	 it  on	 a  black  and white printer will give varying results
       depending on the printer. Sixel output is optimized for a Digital LJ250
       color printer.

       This  example  captures a reversed-contrast full-screen PostScript cap‐
       ture in the file mysnapshot.ps (in the current working directory) after
       a one second delay.

	      dxprint -p -r -t mysnapshot.ps This example captures a black and
	      white PostScript image of the  area  bounded  by	(100,100)  and
	      (300,150) to standard output.

	      dxprint -x100 -y100 -w200 -h50
