This file belongs to the PS_VIEW package.
-----------------------------------------------------------------------------
Version 2.01: June 25th, 1998
-----------------------------------------------------------------------------
The package PS_VIEW belongs to the public domain. You are entitled to do with
the files of which it consists whatever you wish. If you alter a file,
however, please remove the line containing the comment
`This file belongs to the PS_VIEW package.'
in order to avoid a mess.
-----------------------------------------------------------------------------
DIRECTORY OVERVIEW
The package is essentially a PostScript program (hence its portability),
providing an interactive environment for previewing PostScript documents
using Ghostscript interpreter.
It enables scaling, rotating, restart, on-line help, printing the screen,
etc. For more details see below.
The package consists of the following files:
2PS_VIEW.DOC this file
ANSIPRE.BAT DOS batch file, prepares access to ``arrow'' keys,
used by GV.BAT, GVP.BAT, and GVS.BAT;
in order to use it you need to have installed ANSI.SYS
ANSIPOST.BAT DOS batch file, clears settings of ANSIPRE.BAT,
used by GV.BAT, GVP.BAT, and GVS.BAT;
in order to use it you need to have installed ANSI.SYS
GV.PAR parameters for a previewing session using VGA
GV.BAT sample batch file for previewing single page documents
GVP.BAT sample batch file for previewing multi-page documents
GVS.BAT sample batch file for sequential previewing documents
PS_VIEW.PS the ``engine''
PS_HELP.PS on-line help, used by PS_VIEW.PS (to invoke help press F1
or Alt-H during the previewing session)
PS_LOCAL.PS description of local environment, to be adjusted
if necessary
PS_V201.POL the program description (in Polish)
Additionally, the package contains the following files not connected
immediately with the previewing environment, but perhaps of some value for
beginner:
GS.BAT sample batch file for ,,raw'' previewing (without PS_VIEW)
GS.PAR parameters for ,,raw'' previewing, using VGA
GJ.BAT sample batch file for LaserJetIIIp printer (300 dpi)
GJ4P.BAT sample batch file for LaserJetIVp printer (600 dpi)
GJC.BAT sample batch file for color DeskJet550C printer (300 dpi)
GJ.PAR parameters for preparing output for a printer
GJC.PAR parameters for preparing output for color printing
HP3P_510.PS correction file for LJET3 driver for Ghostscript 5.10
(see batch file GJ.BAT)
GAMMA.PS parameter file for color printing (see batch file GJC.BAT)
Moreover, QUIT.PS is referred to. It belongs to the standard Ghostscript
distribution.
-----------------------------------------------------------------------------
LOCATION OF FILES (DOS)
It is assumed that all the package is placed in the directory T:\PS_VIEW.
If another destination place is required, the following files should be
adjusted:
GJ.PAR, GJC.PAR, GS.PAR, GV.PAR,
GG.BAT, GJ.BAT, GJ4P.BAT, GJC.BAT, GS.BAT, GV.BAT, GVP.BAT, GVS.BAT
The program GS386.EXE and all of the batch files are assumed to be in
a directory specified by the DOS environment variable PATH.
-----------------------------------------------------------------------------
USING PS_WIEW WITH OTHER SCREEN DEVICES
In this package the standard VGA is enforced, but
you can use your SVGA device, if it is one of the Ghostscript devices.
We used and tested Ghostscript revision 5.10, compiled by Piotr Strzelczyk,
with following devices:
VGA EGA SVGA16 VESA ATIW TSENG TVGA TVGAGRAY CIRR CIRRGRAY VESB VESC VESD.
For example, if you have the Trident SVGA, your GV.PAR may contain
-sDEVICE=tvga instead of -sDEVICE=vga
and one of the screen resolution settings:
-r61 for the screen resolution 1024 x 768,
-r54 for the screen resolution 800 x 600,
-r41 for the screen resolution 640 x 480.
-----------------------------------------------------------------------------
LIST OF PS_VIEW COMMANDS + SYNOPSIS + ALIASES
-----------------------------------------------------------------------------
In order to preview a document all you need to do is to invoke one of batch
files GV.BAT, GVP.BAT or GVS.BAT with a parameter being the name of the
document to be previewed.
GV.BAT should be used with single page documents (e.g., EPS files),
GVP.BAT---with multi-page documents, conforming the structure of files
generated by Tomas Rokicki's DVIPS driver,
GVS.BAT---provides a sequential access to multi-page documents.
After starting a previewing session you have several possibilities, briefly
described below. In curly braces appear optional parameters. In order to use
``hot-keys'' shown in the fourth column, you have to install ANSI.SYS (in
CONFIG.SYS). After entering a ``normal'' operation (second column) you have
to press [Enter]; ANSI aliases supply [Enter] code automatically.
