- ********
- ******** How to install Ghostscript ********
- ********
-
- To run Ghostscript, you need the executable program, and also some
- external initialization files:
- gs_*.ps (gs_dps1.ps, gs_fonts.ps, gs_init.ps, gs_lev2.ps,
- gs_statd.ps, gs_dbt_e.ps, gs_sym_e.ps)
- uglyr.gsf
- Fontmap
-
- The file name of the executable program depends on the environment;
- see the instructions for the specific platforms below.
-
- The Ghostscript fileset includes a set of fonts (.gsf files); you
- should have them on line as well.
-
- VMS
- ---
-
- Installing Ghostscript on a VMS system requires compiling it first.
- The name of the executable is GS.EXE.
-
- You should install all the files, including the fonts, in the same
- directory as the executable and initialization files. By default,
- this is the directory in which you did the compilation. Consult the
- command file (VMS-CC.MAK or VMS-GCC.MAK) for more details.
-
- If you have DECWindows/Motif installed, you may wish to replace the
- FONTMAP file with the file FONTMAP.VMS. Read the comment at the
- beginning of the latter file for more information.
-
- MS-DOS
- ------
-
- There are two MS-DOS executables in the standard Ghostscript
- distribution:
- - GS.EXE runs on any MS-DOS machine, but is limited to 640K.
- - GS386.EXE runs on any 386 or 486 machine, and will use all
- available extended (not expanded) memory.
-
- You should install all the files except the fonts in C:\GS, and the
- fonts in C:\GS\FONTS.
-
- If you have Adobe Type Manager fonts installed on your system, and you
- wish to use them with Ghostscript, you may wish to replace the FONTMAP
- file with FONTMAP.ATM, and to add to the environment variable GS_LIB the
- name of the directory where the fonts are located (see below for more
- information about GS_LIB). Before you do this, please read carefully the
- license that accompanies the ATM fonts; Aladdin Enterprises takes no
- responsibility for any possible violations of such licenses.
-
- MS Windows
- ----------
-
- The name of the executable is GSWIN.EXE. Ghostscript requires Windows
- 3.1, and you must run Windows in 386 Enhanced or Standard (not Real) mode.
- Since Ghostscript is a large program, you will need to run Windows in
- Enhanced mode (so that it can provide virtual memory) unless you have at
- least 6 Mb of RAM.
-
- You should install all the files except the fonts in C:\GS, and the
- fonts in C:\GS\FONTS.
-
- See under "MS-DOS" above for information about using Adobe Type
- Manager fonts with Ghostscript.
-
- OS/2 2.0
- --------
-
- Ghostscript currently only runs in an OS/2 DOS Box. Please read the
- MS-DOS notes, since they apply to this environment as well.
-
- If you run GS386 in the OS/2 2.0 DOS Box, you must select the
- "ENABLED" setting for the DPMI_DOS_API option of the DOS Box. GS386
- will not run with the "AUTO" setting.
-
- Unix
- ----
-
- Installing Ghostscript on a Unix system requires compiling it first.
- The name of the executable is gs. The makefile installs all the
- files, except the fonts, in /gnu or various subdirectories
- thereof. The fonts should be installed in
- /gnu/lib/ghostscript/fonts. Consult the makefile for more
- details.
-
- ********
- ******** Shell scripts for Ghostscript
- ********
-
- The Ghostscript distribution includes several Unix shell scripts for
- driving Ghostscript in different environments. These are all
- user-contributed code: please contact the user identified in the file, not
- Aladdin Enterprises, if you have questions.
-
- > pv.sh - preview a specified page of a dvi file in an X window.
-
- > sysvlp.sh - System V 3.2 lp interface for parallel printer.
-
- > pj-gs.sh - printing on an H-P PaintJet under HP-UX.
-
- > unix-lpr.sh - queue filter for lpr under Unix.
- > lprsetup.sh - setup for unix-lpr.sh.
-
- If one of these serves your needs, you may be able to skip most of
- the rest of this document.
-
- ********
- ******** How to use the Ghostscript interpreter ********
- ********
-
- To invoke the interpreter, give the command
- gs <filename1> ... <filenameN>
- The interpreter will read in the files in sequence and execute them.
- After doing this, it reads further input from the primary input stream
- (normally the keyboard). Each line (i.e. characters up to a <return>) is
- interpreted separately. To exit from the interpreter, type quit<return>.
- The interpreter also exits gracefully if it encounters end-of-file.
- Typing the interrupt character, e.g., control-C, is also safe.
-
- The interpreter recognizes several switches described below, which may appear
- anywhere in the command line and apply to all files thereafter.
-
- You can get a help message by invoking Ghostscript with
- gs -h
- or
- gs -?
- This message also lists the available devices. For a little more
- information, a one-line description of each device appears near the
- beginning of the file devs.mak.
-
- Choosing the output device
- --------------------------
-
- Ghostscript may be built with multiple output devices. Ghostscript
- normally opens the first one and directs output to it. To use device xyz
- as the initial output device, include the switch
- -sDEVICE=xyz
- in the command line. Note that this switch must precede the first .ps
- file, and only its first invocation has any effect. For example, for
- printer output in a normal configuration that includes an Epson printer
- driver, you might use the shell command
- gs -sDEVICE=epson myfile.ps
- instead of just
- gs myfile.ps
- Alternatively, you can type
- (epson) selectdevice
- (myfile.ps) run
- All output then goes to the printer instead of the display until further
- notice. You can switch devices at any time by using the selectdevice
- procedure, e.g.,
- (vga) selectdevice
- or
- (epson) selectdevice
- As yet a third alternative, you can define an environment variable
- GS_DEVICE as the desired default device name. The order of precedence for
- these alternatives, highest to lowest, is:
- selectdevice
- (command line)
- GS_DEVICE
- (first device in build list)
-
- To select the density on a printer, use
- gs -sDEVICE=<device> -r<xres>x<yres>
- For example, on a 9-pin Epson-compatible printer, you can get the
- lowest-density (fastest) mode with
- gs -sDEVICE=epson -r60x72
- and the highest-density mode with
- gs -sDEVICE=epson -r240x72.
- On a 24-pin printer, the lowest density is
- gs -sDEVICE=epson -r60x60
- and the highest-density 24-pin mode is
- gs -sDEVICE=epson -r360x180
-
- If you select a printer as the output device, Ghostscript also allows you
- to control where the device sends its output. Normally, output goes
- directly to the printer (PRN) on MS-DOS systems, and to a scratch file on
- Unix or VMS systems. To send the output to a series of files foo1.xyz,
- foo2.xyz, ..., use the switch
- -sOutputFile=foo%d.xyz
- (For compatibility with older versions of Ghostscript, -sOUTPUTFILE=
- also works.) The %d is a printf format specification; you can use
- other formats like %02d. Each file will receive one page of output.
- Alternatively, to send the output to a single file foo.xyz, with all
- the pages concatenated, use the switch
- -sOutputFile=foo.xyz
-
- On Unix systems, you can send the output directly to a pipe. For
- example, to pipe the output to the command `lpr' (which, on many Unix
- systems, is the command that spools output for a printer), use the
- switch
- -sOutputFile=\|lpr
- You can also send output to stdout for piping with the switch
- -sOutputFile=-
- In this case you must also use the -q switch, to prevent Ghostscript from
- writing messages to stdout.
-
- To find out what devices are available, type
- devicenames ==
- after starting up Ghostscript. Alternatively you can use the -h or
- -? switch in the command line, as described above.
-
- Device configuration
- --------------------
-
- Ghostscript is normally configured to expect U.S. letter paper,
- although there is a way to make A4 paper the default for certain
- printers at compilation time (see devs.mak for details). To select a
- different paper size as the default, use the switch
- -sPAPERSIZE=a_known_paper_size
- e.g.,
- -sPAPERSIZE=a4
- or
- -sPAPERSIZE=legal
- You can use any paper size listed in the table at the beginning of
- gs_statd.ps. (Individual documents can also specify a paper size,
- which will take precedence over the one specified on the command
- line.)
-
- Printing on a Hewlett-Packard LaserJet at full resolution (300 DPI)
- requires a printer with at least 1.5 Mb of memory. 150 DPI printing
- requires only .5 Mb. You can select 150 DPI printing with the command
- line switch
- -r150
- This is not necessary on DeskJet printers.
-
- On MS-DOS systems using the Borland compiler, if Ghostscript gives
- you a 'limitcheck in setdevice' error, it may mean Ghostscript's
- standard buffer size wasn't large enough. Likewise, if Ghostscript
- gives you a 'VMerror in setdevice' error, it means the buffer size
- was too large. You can use the -dBufferSpace= switch to set the
- buffer size to a different value, e.g.,
- -dBufferSpace=50000
- The default value is 25000; the smallest value Ghostscript accepts is
- 10000; the largest valid value is 65000.
-
- File searching
- --------------
-
- When looking for the initialization files (gs_*.ps), the files related to
- fonts, or the file for the 'run' operator, Ghostscript first tries opening
- the file with the name as given (i.e., using the current working directory
- if none is specified). If this fails, and the file name doesn't specify
- an explicit directory or drive (i.e., doesn't begin with '/' on Unix
- systems; doesn't contain a ':' or begin with a '/' or '\' on MS-DOS
- systems; doesn't contain a ':' or a square bracket on VMS systems),
- Ghostscript will try directories in the following order:
-
- - The directory/ies specified by the -I switch(es) in the command
- line (see below), if any;
-
- - The directory/ies specified by the GS_LIB environment variable,
- if any;
-
- - The directory/ies specified by the GS_LIB_DEFAULT macro in the
- Ghostscript makefile, if any.
-
- Each of these (GS_LIB_DEFAULT, GS_LIB, and -I parameter) may be either a
- single directory, or a list of directories separated by a character
- appropriate for the operating system (':' on Unix systems, ';' on VMS
- systems, ';' on MS-DOS systems).
-
- When Ghostscript starts up, it also looks at the GS_FONTPATH environment
- variable, which is also a list of directories. It goes to those
- directories and looks for all files that appear to contain PostScript
- fonts; it then effectively adds all those files and fonts to its internal
- copy of the Fontmap (the catalog of fonts and the files that contain
- them).
-
- Temporary files
- ---------------
-
- By default, Ghostscript creates temporary files named _temp_XX.XXX in the
- current directory on MS-DOS and VMS systems, and named gs_XXXXX in the
- /tmp directory on Unix systems. You can change the directory in which
- Ghostscript will create these files by setting the TEMP environment
- variable to the name of the directory.
-
- Ghostscript currently doesn't do a very good job of deleting temporary
- files when it exits; you may have to delete them manually from time to
- time.
-
- ********
- ******** Notes on specific platforms ********
- ********
-
- VMS
- ---
-
- On VMS systems, the last character of each "directory" name indicates what
- sort of entity the "directory" references. If the "directory" name ends
- with a colon, it is taken as referring to a logical device, e.g.:
- $ DEFINE GHOSTSCRIPT_DEVICE DUA1:[GHOSTSCRIPT_14]
- $ DEFINE GS_LIB GHOSTSCRIPT_DEVICE:
- If the "directory" name ends with a closing square bracket, it is taken as
- referring to a real directory, e.g.:
- $ DEFINE GS_LIB DUA1:[GHOSTSCRIPT]
-
- To run Ghostscript with switches, you must type a command like
-
- $ gs "-dNODISPLAY"
-
- because the C run time library will convert the command
- parameters/arguments to lowercase unless you enclose them in double quotes
- which preserves the case.
-
- If you are on an X Windows display (for which gs is built), you can do
-
- $ set display/create/node="domain-name"/transport=tcpip
-
- For example,
-
- $ set display/create/node="doof.city.com"/transport=tcpip
-
- and then run Ghostscript
-
- $ gs
-
- If you write printer output to a file and then want to print the file
- later, use the "/PASSALL" qualifier to the PRINT command.
-
- MS-DOS
- ------
-
- If you are running Ghostscript on a MS-DOS machine with a display
- that is not EGA/VGA compatible, you must use the Borland compiler.
- You must build Ghostscript with the BGI driver as the default, and
- you will need the appropriate .BGI file from the Borland Turbo C
- library. (Ghostscript includes the EGA/VGA driver in the
- executable.)
-
- If you are using the BGI driver, two additional environment variables
- become relevant:
-
- BGIPATH - defines the directory where Ghostscript will look for
- the appropriate BGI driver. If BGIPATH is not defined, Ghostscript will
- look in the directory defined as BGIDIR in the makefile. In either case,
- if no driver is found in the designated directory, Ghostscript will look
- in the current directory.
-
- BGIUSER - a string of the form nn.dname, where nn is a hexadecimal
- number giving a display mode and dname is the name of a file containing a
- user-supplied BGI driver. If BGIUSER is defined and the BGI device is
- selected, Ghostscript will supply nn as the display mode and will obtain
- the driver from the file named dname.
-
- Some applications, such as Microsoft Word, require a prologue in front of
- the PostScript files they output. In the case of Word, this is one of the
- *.ini files included with the Word distribution. Other applications may
- require other prologues. These may be specified on the Ghostscript
- command line, e.g.,
- gs prologue.ini myfile.ps
-
- X Windows
- ---------
-
- Ghostscript looks for the following resources under the program name
- "ghostscript" and class name "Ghostscript":
-
- Name Class Default
- ---- ----- -------
- background Background white
- foreground Foreground black
- borderColor BorderColor black
- borderWidth BorderWidth 1
- geometry Geometry NULL
- xResolution Resolution **
- yResolution Resolution **
- useExternalFonts UseExternalFonts true
- useScalableFonts UseScalableFonts true

- maxRGBRamp MaxRGBRamp 5
- useBackingPixmap UseBackingPixmap true
- useXPutImage UseXPutImage true
- useXSetTile UseXSetTile true
- regularFonts RegularFonts see below
- symbolFonts SymbolFonts see below
- dingbatFonts DingbatFonts see below
-
- ** Calculated from display metrics.
-
- Notes on Resources:
-
- The geometry resource only affects window placement.
-
- Resolution is given in pixels per inch.
-
- The font tolerance gives largest acceptable difference in
- height of the screen font. The tolerance is expressed as
- a percentage of the height of the desired font.
-
- The palette resource can be used to restrict ghostscript to
- using a grayscale or monochrome palette.
-
- The maxRGBRamp and maxGrayRamp control the maximum number of
- colors that ghostscript allocates ahead of time for the dither
- cube/ramp. Ghostscript will never preallocate more than half
- of the cells in a colormap.
-
- To use native X11 fonts, ghostscript must map PostScript font names to
- the XLFD font names. The regularFonts, symbolFonts, and dingbatFonts
- resources give the name mapping for different encodings. The XLFD font
- name in the mapping must contain seven dashes. The X driver adds the
- additional size and encoding fields to bring the total number of dashes
- in the font name to 14. Here are the default font mappings:
-

- To set these resources, put them in a file (such as ~/.Xdefaults) in the
- following form:
-
- Ghostscript*geometry: -0+0
- Ghostscript*xResolution: 72
- Ghostscript*yResolution: 72
-
- Then load the defaults into the X server:
-
- % xrdb -merge ~/.Xdefaults
-
- On H-P systems, Ghostscript will take advantage of the "HP XLFD
- Enhancements" to use native X11 fonts for fonts that are anamorphically
- scaled, rotated, or mirrored. If the user has installed these changes to
- their X or font server, they will automatically be used when appropriate.
-
- Normal switches
- ---------------
-
- @filename
- Causes Ghostscript to read filename and treat its
- contents the same as the command line. (This is
- intended primarily for getting around DOS'
- 128-character limit on the length of a command line.)
- Switches or file names in the file may be separated by
- any amount of white space (space, tab, line break);
- there is no limit on the size of the file.
-
- -- filename arg1 ...
- Takes the next argument as a file name as usual, but takes
- all remaining arguments (even if they have the syntactic
- form of switches) and defines the name ARGUMENTS in
- userdict (not systemdict) as an array of those strings,
- *before* running the file. When Ghostscript finishes
- executing the file, it exits back to the shell.
-
- -Dname=token
- -dname=token
- Define a name in systemdict with the given definition.
- The token must be exactly one token (as defined by the
- 'token' operator) and must not contain any whitespace.
-
- -Dname
- -dname
- Define a name in systemdict with value=null.
-
- -Sname=string
- -sname=string
- Define a name in systemdict with a given string as value.
- This is different from -d. For example,
- -dname=35
- is equivalent to the program fragment
- /name 35 def
- whereas
- -sname=35
- is equivalent to
- /name (35) def
-
- -q
- Quiet startup -- suppress normal startup messages,
- and also do the equivalent of -dQUIET.
-
- -ffilename
- Executes the given file, even if its name begins with a -.
-
- -gnumber1xnumber2
- Equivalent to -dDEVICEWIDTH=number1 and
- -dDEVICEHEIGHT=number2. This is for the benefit of
- devices (such as X11 windows and VESA displays) that require
- (or allow) width and height to be specified.
-
- -rnumber
- -rnumber1xnumber2
- Equivalent to -dDEVICEXRESOLUTION=number1 and
- -dDEVICEYRESOLUTION=number2. This is for the benefit of
- devices (such as printers) that support multiple
- X and Y resolutions.
-
- -Idirectories
- Adds the designated list of directories at the head of the
- search path for library files.
-
- -
- This is not really a switch. It indicates to Ghostscript
- that the standard input is coming from a file or a pipe.
- Ghostscript reads from stdin until reaching end-of-file,
- executing it like any other file, and then continues
- processing the command line. At the end of the command
- line, Ghostscript exits rather than going into its
- interactive mode.
-
- Note that gs_init.ps makes systemdict read-only, so the values of names
- defined with -D/d/S/s cannot be changed (although, of course, they can be
- superseded by definitions in userdict or other dictionaries.)
-
- Special names
- -------------
-
- -dDISKFONTS
- causes individual character outlines to be loaded from the disk
- the first time they are encountered. (Normally Ghostscript loads all the
- character outlines when it loads a font.) This may allow loading more
- fonts into RAM, at the expense of slower rendering.
-
- -dNOBIND
- disables the 'bind' operator. Only useful for debugging.
-
- -dNOCACHE
- disables character caching. Only useful for debugging.
-
- -dNODISPLAY
- suppresses the normal initialization of the output device. This
- may be useful when debugging.
-
- -dNOPAUSE
- disables the prompt and pause at the end of each page. This may
- be desirable for applications where another program is 'driving'
- Ghostscript.
-
- -dNOPLATFONTS
- disables the use of fonts supplied by the underlying platform
- (X Windows or Microsoft Windows). This may be needed if the platform
- fonts look undesirably different from the scalable fonts.
-
- -dSAFER
- disables the deletefile and renamefile operators, and the
- ability to open files in any mode other than read-only. This may be
- desirable for spoolers or other sensitive environments.
-
- -dWRITESYSTEMDICT
- leaves systemdict writable. This is necessary when running
- special utility programs such as font2c and pcharstr, which must bypass
- normal PostScript access protection.
-
- -sDEVICE=device
- selects an alternate initial output device, as described above.
-
- -sOutputFile=filename
- selects an alternate output file (or pipe) for the initial output
- device, as described above.
-
- Debugging switches
- ------------------
-
- The -Z switch only applies if the interpreter was built for a
- debugging configuration (DEBUG=1 or -DDEBUG selected at compile
- time).
-
- -A Turn on allocator debugging (gs_malloc and gs_free).
-
- -e Turn on tracing of error returns from operators.
-
- -E Abort when any operator returns with an error.
-
- -Mn Force the interpreter's allocator to acquire additional
- memory in units of nK, rather than the default (currently
- 20K on MS-DOS systems, 50K on Unix). n is a positive
- decimal integer (not exceeding 63 on MS-DOS systems).
-
- -Zxxx Turn on debugging printout.
- Each of the xxx characters selects an option:
- if the string is empty, all options are selected.
- Case is significant.
- 1 = type 1 font interpreter (type1addpath)
- 2 = curve subdivider/rasterizer
- a = allocator (large blocks only)
- A = allocator (all calls)
- b = bitmap image processor
- B = bitmap images, detail
- c = color/halftone mapper
- d = dictionary put/undef
- f = fill algorithm (summary)
- F = fill algorithm (detail)
- g = gsave/grestore[all]
- h = halftone renderer
- i = interpreter, just names
- I = interpreter, everything
- k = character cache & xfonts
- K = character cache, every access
- l = command lists, bands
- L = command lists, everything
- m = makefont and font cache
- n = name lookup (new names only)
- o = outliner (stroke)
- p = path tracer
- q = clipping
- r = arc renderer
- s = scanner
- t = tiling algorithm
- u = undo saver (for save/restore)
- U = undo saver, more detail
- v = rectangle fill
- V = device-level output
- w = compression encoder/decoder
- x = transformations
- y = Type 1 hints
- Y = Type 1 hints, every access
- z = trapezoid fill
-
