dpsexec is a Display PostScript program that
allows the user to interact directly with the PostScript interpreter through
a command interface. dpsexec reads lines of text from standard input and
passes each line to the PostScript interpreter for execution. It creates
a window that displays the results of graphics operations as they are executed.
dpsexec exits when end of file is reached on standard input, or when the
user types "quit<return>", which executes the PostScript quit operator.
By
default, dpsexec executes the PostScript executive operator before it accepts
any user input. This operator puts the PostScript interpreter in "interactive
executive" mode so that the user can control the interpreter directly.
In this mode, the PostScript interpreter supports certain line-editing
functions and prompts the user when it is ready to execute more input. See
section 2.4.4, "Using the Interpreter Interactively," of the PostScript Language
Reference Manual, Second Edition, for detailed information on this mode
of operation.
- -display name
- specifies the display on which to open
a connection to the Display PostScript system. If no display is specified,
the DISPLAY environment variable is used.
- -sync
- establishes a synchronous
connection with the specified X display.
- -backup
- uses backing store for the
window in which graphics are displayed, if possible. This is generally
only effective with the DPS NX system.
- -noexec
- prevents dpsexec from entering
"interactive executive" mode. The primary effect of this option is to
inhibit printing the PS> prompt before each line of input is accepted. This
option is useful when dpsexec is run with standard input redirected from
a file or a pipe.
- -root
- tells dpsexec to draw into the root window instead
of into a window that it creates.
- -drawable windowId
- tells dpsexec to draw
into the specified window instead of into a window that it creates.
- -height
n
- sets the height of the created window.
- -width n
- sets the width of the created
window.
PostScript language error messages are printed to standard
output.
