PN 93000131C GNU Ghostscript Release Notes Version 2.6.1 Software Package P/N 75000131C Diskette P/N 40000833C V2.6.1 (3.5") Diskette P/N 40000834C V2.6.1 (5.25") INTRODUCTION This package contains GNU Ghostscript, an interpreter for the PostScript language. This version of Ghostscript has been compiled with support for creating FAX format output files, and includes a shell script, ps2fax which will convert PostScript level 1 to FAX for use with the DigiFAX System. GNU Ghostscript is a printer emulator, and can be used to convert Postscript printer streams produced by word processors and other applications to FAX format. DISKETTES All of the software diskettes included with this product are specially formatted to be readable by both tar and cpio. This means that they can be read using either the SCO XENIX or UNIX custom command, or by the installpkg command found on ISC, AT&T, Intel, Everex, and Dell versions of UNIX/386. Although your operating system may support installation of either of these types of formats, we recommend that you use the command shown in the following table to install the diskettes: Operating System Installation Command __________________________________________________________________ AT&T UNIX System V/386 Release 3.2.x installpkg Dell UNIX System V/386 Release 3.2.x installpkg Everex Esix System V/386 Release 3.2.x installpkg INTERACTIVE 386/ix Release 2.0.x sysadm installpkg INTERACTIVE UNIX System V/386 Release 3.2.x sysadm installpkg SCO XENIX System V/386 Release 2.3.2 custom SCO UNIX System V/386 3.2.x custom SCO Open Desktop Release 1.x custom All versions of System V Release 4.0 installpkg All versions of System V Release 4.2 installpkg __________________________________________________________________ __________ PostScript is a trademark of Adobe Systems Incorporated. - 1 - PN 93000131C GNU Ghostscript Release Notes Version 2.6.1 If you suspect that a diskette is bad, you can use the UNIX sum command to verify the diskette.

The other variants of the command name produce output suitable for sending to various non- PostScript printers. Note that all of these command names are links to the same shell script. ps2fax performs printer emulation similar to the faxjet printer emulator, except that the printer being emulated is a PostScript printer instead of an HP LaserJet Series II printer. The -ofaxfile option specifies the output file name for the FAX format output. The -l option requests low resolution FAX output. The -a option forces the use of Adobe fonts if they have been installed on your system. The -g option forces the use of the GNU fonts. Otherwise, the default fonts are speci- fied by the DEF_FONTS environment variable inside this script. EXAMPLES To convert a PS file to FAX format, use this command: $ ps2fax -o pagemaker.fax pagemaker.ps Note that the faxsend or faxdir programs will automatically run ps2fax to convert files suffixed with .ps to FAX format. You can use ps2fax to test the conversion process, or to preconvert a file to FAX format. Some word processors assume that a prologue file of Postscript instructions has been previously downloaded to the printer, and do not include the prologue in the printer stream when printing to a file. If your word processor does this, you will need to find this prologue file, and prepend it to the printer stream that is sent through ps2fax. Otherwise, you will get errors from the gs interpreter. FONTS The GNU fonts are included with this package. If you would like to use genuine Adobe fonts instead, please see the README file in /usr/local/lib/ghostscript/fonts-adobe.

To invoke the inter- preter, give the command: gs filename1 ... filenameN The interpreter will read in the PostScript files in sequence and execute them. It is recommended, but not required, that the files be named with the suffix .ps. After doing this, gs reads further input from the primary input stream (normally the keyboard). Each line (i.e. char- acters up to a ) is interpreted separately. To exit from the interpreter, type quit. 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 invok- ing Ghostscript with gs -? This message also lists the available devices. OUTPUT DEVICES 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 confi- guration 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., (laserjet) selectdevice or (epson) selectdevice As yet a third alternative, you can define an environment variable GS_DEVICE as the desired default device name. The GNU Last change: Aladdin Enterprises 1 gs(1) USER COMMANDS gs(1) 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 -rxresxyres 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 out- put. Normally, output goes directly to the printer (PRN) on MS-DOS systems, and to a scratch file on Unix or VMS sys- tems. To send the output to a series of files foo1.xyz, foo2.xyz, ..., use the switch -sOUTPUTFILE=foo%d.xyz The %d is a printf format specification; you can use other formats like %02d. Each file will receive one page of out- put. 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 lp (which, on many Unix systems, is the command that spools output for a printer), use the switch -sOUTPUTFILE=\|lp To find out what devices are available, type devicenames == after starting up Ghostscript. Alternatively you can use the -? switch in the command line, as described above. DEVICE LIMITATIONS Printing on a Hewlett-Packard DeskJet or 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 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 GNU Last change: Aladdin Enterprises 2 gs(1) USER COMMANDS gs(1) 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). OPTIONS @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 GNU Last change: Aladdin Enterprises 3 gs(1) USER COMMANDS gs(1) -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 mes- sages, and also do the equivalent of -dQUIET. -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. -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. -I=fPdirectories 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, exe- cuting it like any other file, and then con- tinues 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 -dASCIIOUT Disables Ghostscript's normal behavior; instead, writes strings to stdout that would have been displayed or printed. For more information, see the file gs_2asc.ps. GNU Last change: Aladdin Enterprises 4 gs(1) USER COMMANDS gs(1) -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 appli- cations where another program is `driving' Ghostscript. -dSAFER Disables the deletefile and renamefile opera- tors, 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 neces- sary 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.

LICENSE GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make GNU Last change: Aladdin Enterprises 6 gs(1) USER COMMANDS gs(1) sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free pro- grams; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to cer- tain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any prob- lems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redis- tributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The ``Program'', below, refers to any such program or work, and a ``work based on the Program'' means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or GNU Last change: Aladdin Enterprises 7 gs(1) USER COMMANDS gs(1) translated into another language. (Hereinafter, translation is included without limitation in the term ``modifica- tion''.) Each licensee is addressed as ``you''. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents con- stitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, pro- vided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or pub- lish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a war- ranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Pro- gram itself is interactive but does not normally print such an announcement, your work based on the Program is GNU Last change: Aladdin Enterprises 8 gs(1) USER COMMANDS gs(1) not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the GNU Last change: Aladdin Enterprises 9 gs(1) USER COMMANDS gs(1) work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface defini- tion files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include any- thing that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the execut- able. If distribution of executable or object code is made by offering access to copy from a designated place, then offer- ing equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distri- bute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you per- mission to modify or distribute the Program or its deriva- tive works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distri- buting the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modi- fying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the reci- pients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the GNU Last change: Aladdin Enterprises 10 gs(1) USER COMMANDS gs(1) conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforce- able under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contribu- tions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is wil- ling to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is res- tricted in certain countries either by patents or by copy- righted interfaces, the original copyright holder who places the Program under this License may add an explicit geograph- ical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and ``any later version'', you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foun- dation. If the Program does not specify a version number of this License, you may choose any version ever published by GNU Last change: Aladdin Enterprises 11 gs(1) USER COMMANDS gs(1) the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are dif- ferent, write to the author to ask for permission. For software which is copyrighted by the Free Software Founda- tion, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all deriva- tives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRAN- TIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PUR- POSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFEC- TIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redis- tribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the ``copyright'' line and a pointer to where the full notice is found.
