-
 
-<p>
 
-(This is not a complete list of new features: see <a href="News.htm">the
 
-news</a> for details.)
 
-
 
-<p>
 
-Ghostscript now handles essentially all of PostScript LanguageLevel 3 and
 
-PDF 1.3 (Acrobat 4.x compatibility).  See <a
 
-href="Language.htm"><b>Language.htm</b></a> for details.
 
-
 
-<p>
 
-The PDF writer now implements most of the Acrobat (TM) Distiller parameters
 
-for compressing and downsampling images.
 
-
 
-<p>
 
-The PDF writer now recognizes nearly all varieties of pdfmark, other than
 
-the Distiller 3.0 "named object" pdfmarks and the Distiller 4.0 "document
 
-structure" pdfmarks.
 
-
 
-<p>
 
-The PDF writer now handles text in all fonts, not just the 14 built-in ones,
 
-and implements the Distiller parameters affecting font embedding and
 
-subsetting.  (It still usually converts double-byte fonts to bitmaps.)
 
-
 
-<p>
 
-16- and 24-bit X Windows displays are now fully supported.
 
-
 
-<p>
 
-You now need only the header files and shared libraries, not the source
 
-code, if you want to use precompiled versions of the jpeg, libpng, or zlib
 
-libraries.
 
-
 
-<p>
 
-The syntax
 
-<b><tt>%</tt></b><em>iodevice</em><b><tt>%</tt></b><em>filename</em> is now
 
-supported with the <b><tt>-sOutputFile=</tt></b> switch, allowing you to
 
-send raster output to a piped command.
 
-
 
-<p>
 
-You can now use MMK or MMS to build Ghostscript on OpenVMS systems.
 
-
 
-<p>
 
-For driver writers, there are improved facilities for planar output,
 
-rasterizing directly into a driver-provided buffer, detecting bands that are
 
-all white or that only use a subset of the colorants, and providing CRDs
 
-from the driver.
 
-
 
-<p>
 
-The driver API now includes facilities for passing high-level text
 
-operations, completing the set of high-level operations (bitmap images and
 
-vector graphics were implemented in 5.50).  See <a href="Drivers.htm">the
 
-documentation</a> for details.
 
-
 
-<p>
 
-Ghostscript as a dynamically linked library is now supported on the Mac as
 
-well as on Windows.
 
-
 
-<p>
 
-GNU readline was supported in most of the beta distributions for 6.0, but
 
-was removed at the last minute because of objections from the Free Software
 
-Foundation.  Please see <a href="Make.htm#GNU_readline">here</a> for more
 
-information.
 
-
 
-<h2><a name="Changes"></a>Changes (since release 5.50)</h2>
 
-
 
-<h3>Directories and build procedure</h3>
 
-
 
-<p>
 
-The files in the release now have a more complex directory structure.  In
 
-the table below, <em>top</em> refers to the top-level directory,
 
-<b><tt>gs</tt></b><em>n.nn</em>.
 
-
 
-<p>
 
-The <em>top</em><b><tt>/</tt></b> is where you create a link to the
 
-appropriate makefile in <em>top</em><b><tt>/src/</tt></b>.  On all systems
 
-other than MS Windows, the build procedure does not write into this
 
-directory.
 
-
 
-<p>
 
-The files included in the Ghostscript release now are found in five
 
-subdirectories.
 
-
 
-<ul>
 
-<li><em>top</em><b><tt>/src/</tt></b> contains the C/C++ source code, the
 
-makefiles, and all other files needed to build the program.  The build
 
-procedure reads from this directory but does not write into it.  Nothing in
 
-this directory is needed at run time.
 
-
 
-<li><p><em>top</em><b><tt>/lib/</tt></b> contains PostScript and script
 
-files needed at run time.  The build procedure reads from this directory but
 
-does not write into it.  The contents of this directory are needed at run
 
-time and are copied by the Unix <b><tt>make install</tt></b> command.
 
-
 
-<li><em>top</em><b><tt>/doc/</tt></b> contains documentation.  Copied by
 
-<b><tt>make install</tt></b>.
 
-
 
-<li><em>top</em><b><tt>/man/</tt></b> contains Unix <b><tt>man</tt></b>
 
-pages.  Copied by <b><tt>make install</tt></b>.
 
-
 
-<li><em>top</em><b><tt>/examples/</tt></b> contains sample PostScript and
 
-PDF files.  Copied by <b><tt>make install</tt></b>.
 
-
 
-</ul>
 
-
 
-<p>
 
-The build procedure creates two additional subdirectories,
 
-<em>top</em><b><tt>/obj/</tt></b> (or <b><tt>debugobj</tt></b> or
 
-<b><tt>pgobj</tt></b>) and <em>top</em><b><tt>/bin/</tt></b>.  See the
 
-documentation on <a href="Make.htm">how to build Ghostscript</a> for more
 
-information.
 
-
 
-<h2>Other changes</h2>
 
-
 
-<p>
 
-If you are a developer working with the Ghostscript code in any way other
 
-than writing or modifying drivers, please read all of the "Incompatible
 
-changes" sections of the <a href="News.htm">release news</a> for important
 
-information.

-<h2><a name="Known_problems"></a>Known problems</h2>

-See the <a href="News.htm">release news</a> for details.
 
-
 
-<h3><a name="Usage"></a>Usage</h3>
 
-
 
-<p>
 
-On a DOS system, interrupting the interpreter by typing control-C doesn't
 
-restore the display mode.
 
-
 
-<h3><a name="Limitations"></a>Limitations</h3>
 
-
 
-<p>
 
-<b><tt>serialnumber</tt></b> returns the same value in all copies.
 
-
 
-<p>
 
-Some floating point exceptions terminate the interpreter, rather than
 
-producing a <b><tt>limitcheck</tt></b> error.
 
-
 
-<p>
 
-The <b><tt>DCTEncode</tt></b> filter disregards the <b><tt>Blend</tt></b>
 
-parameter, and uses different <b><tt>QuantTables</tt></b> and
 
-<b><tt>HuffTables</tt></b> from Adobe's.
 
-
 
-<p>
 
-The DCT filters do not support nonintegral sample ratios.  Also,
 
-<b><tt>DCTEncode</tt></b> will not create files with Sum(HS&times;VS)&gt;10
 
-(regardless of the value of the <b><tt>Relax</tt></b> parameter) because
 
-they violate the JPEG standard; but <b><tt>DCTDecode</tt></b> will read
 
-such files.
 
-
 
-<p>
 
-The size of the execution stack cannot be changed dynamically.  (However,
 
-the sizes of the operand and dictionary stacks can be changed.)
 
-
 
-<p>
 
-<b><tt>Separation</tt></b> and <b><tt>DeviceN</tt></b> color spaces are
 
-implemented, but devices that actually produce color separations are not

-Some path-building operations that would generate a device coordinate

-<h2><a name="Overview"></a>An overview of Ghostscript</h2>
 
-
 
-<p>
 
-Ghostscript is the name of a set of software that provides:
 
-
 
-<ul>
 
-<li>An interpreter for the <b>PostScript</b><small><sup>TM</sup></small>
 
-language and the Adobe <b>Portable Document Format</b> (<b>PDF</b> --
 
-sometimes confused with Acrobat, Adobe's PDF browser and editor product);
 
-
 
-<li>Input modules (utilities) for reading a variety of raster formats,
 
-including <b>CMYK</b>, <b>GIF</b>, <b>JFIF</b> (<b>JPEG</b>), <b>MIFF</b>,
 
-<b>PBM</b>/<b>PGM</b>/<b>PPM</b>, and <b>PCX</b>;
 
-
 
-<li>Output modules (drivers) for a wide variety of window systems (including
 
-X Windows and Microsoft Windows), raster file formats, and printers, as well
 
-as a PDF output module that implements functions similar to Adobe's
 
-Acrobat<small><sup>TM</sup></small> Distiller<small><sup>TM</sup></small>
 
-product; and
 
-
 
-<li>The Ghostscript library, a set of procedures to implement the graphics
 
-and filtering capabilities that are primitive operations in the PostScript
 
-language and in PDF.
 
-</ul>
 
-
 
-<p>
 
-In simple terms, this means that Ghostscript can read a PostScript or PDF
 
-file and display the results on the screen or convert them into a form you
 
-can print on a non-PostScript printer. Especially together with several
 
-popular <a href="#Previewers">previewers</a>, with Ghostscript you can view
 
-or print an entire document or even isolated pages, even if your computer
 
-doesn't have Display PostScript and your printer doesn't handle PostScript
 
-itself.

-
 
-<p>
 
-Neither artofcode LLC nor any organization known to us currently offers

-just want to use Ghostscript and not redistribute it as part of a product.
 
-Companies that include Ghostscript in their products under a commercial
 
-license (see next section) may offer support to end-users, but it would be
 
-support for the company's own product, not for Ghostscript <em>per se</em>.
 
-
 
-<p>
 
-Nothing in the GNU or AFPL licenses prevents anyone from providing
 
-support for Ghostscript, either free or commercial.  We would be happy to
 
-include in the Ghostscript documentation the contact information for anyone
 
-who wants to offer such support.

-<h3><a name="Commercial_use"></a>What about commercial use?</h3>
 
-
 
-<p>
 
-GNU Ghostscript may not be incorporated into commercial products which
 
-forbid copying or for which customers cannot obtain source code for no more
 
-than the cost of reproduction, although it may be distributed ("aggregated")
 
-with commercial products; AFPL Ghostscript may not be incorporated into
 
-commercial products at all, and may be distributed commercially only under
 
-extremely limited circumstances.  However, Ghostscript is also available for
 
-commercial licensing, which in addition to the right to incorporate
 
-Ghostscript into commercial products includes support, a limited warranty,
 
-high-quality fonts, and other benefits.  For more information about
 
-commercial licensing of Ghostscript, please contact our commercial

-<h3><a name="Platforms"></a>What platforms does Ghostscript run on?</h3>
 
-
 
-<p>
 
-Ghostscript is written entirely in C (with some optional assembly-language
 
-accelerators for DOS platforms), with special care taken to make it run
 
-properly on systems of either byte order ("low-endian" and "high-endian")
 
-and of various word lengths.  GNU Ghostscript is known to run on the
 
-following platform families:
 
-
 
-<ul>
 
-<li>A wide variety of Unix systems using X Windows version 11, releases 4, 5,
 
-and 6, including
 
-
 
-<ul compact>
 
-<li>Sun-3, Sun-4, Sun-386i, Sun SPARCStation with SunOS 4 and Solaris 2.[56]
 
-<li>Generic Intel-based systems running Linux, 386/ix, 386BSD, FreeBSD, ISC Unix, SCO Unix, and Solaris
 
-<li>H-P 9000/300 and 9000/800
 
-<li>DECStation 2100, 3100, and 5xxx
 
-<li>Alpha systems running Digital Unix
 
-<li>VAX running Ultrix
 
-<li>Sequent Symmetry
 
-<li>Convex C1 and C2
 
-<li>Tektronix 4300
 
-<li>SGI Iris Indigo
 
-<li>4.4BSD Unix systems (FreeBSD on Intel)
 
-<li>NetBSD on Intel, Sun SPARC, Motorola M68K (Apple, Amiga, Sun, H-P), and VAX
 
-</ul>
 
-
 
-<li>Sun workstations running SunView
 
-
 
-<li>VAX and Alpha systems running OpenVMS with X11 compiled with
 
-either DEC C or gcc
 
-</ul>
 
-
 
-<p>
 
-AFPL Ghostscript is known to run on all of the above, and additionally
 
-on the following platform families:
 
-
 
-<ul>
 
-<li>IBM PC and compatibles with EGA, VGA, SuperVGA, or compatible graphics
 
-under MS-DOS 3.1, 3.3, 5.0, or 6.22, and Microsoft Windows 3.1, NT, 95, or
 
-98;
 
-
 
-<li>IBM PC and compatibles under DR DOS 6.0;
 
-
 
-<li>IBM PC and compatibles under OS/2 2.0, 2.1 and Warp 3.0.
 
-
 
-<li>Apple Macintosh with System 7 or later, both Motorola 680x0 and PowerPC
 
-native. For specific information on the Macintosh implementation, see
 
-
 
-<blockquote>
 
-<a href="http://www.cs.wisc.edu/~ghost/macos/" 
-class="offsite">http://www.cs.wisc.edu/~ghost/macos/</a>
 
-</blockquote>
 
-</ul>
 
-
 
-<p>
 
-It is very likely that Ghostscript will run under other versions of DOS,
 
-and other versions of Unix that support X11, but it has not been tested in
 
-these environments.  (Ghostscript does not run well on PC-compatibles with
 
-Hercules display cards, since text and graphics output interfere with each
 
-other, but you can work around this by redirecting the text output to a file.)
 
-
 
-<h4><a name="Third-party_platforms"></a>Ports done by users</h4>
 
-

-Ghostscript has been ported to a number of platforms by users, who are

-<h2><a name="How_to_help"></a>How you can help improve Ghostscript</h2>
 
-
 
-<p>
 
-The most valuable thing you can do to help improve Ghostscript is to help
 
-test it.  We make three different grades of release available, each of
 
-which needs a different kind of testing.
 
-
 
-<ul>
 
-<li><em>Stable</em> releases are made available about every 9 months, after
 
-a beta test period.  Reporting problems as described <a
 
-href="#Reporting_problems">above</a> often results in a fix being posted on
 
-our Web site.
 
-</ul>
 
-
 
-<ul>
 
-<li><em>Beta</em> releases are posted starting about 6 weeks before a
 
-planned public release.  These are candidates for public release, and need
 
-intensive testing.
 
-</ul>
 
-
 
-<ul>
 
-<li><em>Development</em> releases are posted every few weeks.  These are not
 
-supposed to be good enough for general use, but testing them is still very
 
-helpful, since it gets problems corrected before the intensive beta test
 
-period.
 
-</ul>
 
-
 
-<p>
 
-You can always find the current public release and the current beta or
 
-tester release on our <a href="http://www.cs.wisc.edu/~ghost/">Web
 
-site</a>.  If you would like to be notified when new beta or tester releases
 
-are posted, please <a href="#Contacting_us">contact us</a>.
 
-
 
-<p>
 
-There are also some useful projects that we don't have enough resources to
 
-work on, and with which we would appreciate help.  See <a

-We don't share any of the above information with anyone else, with two
 
-exceptions:
 
-
 
-<ul><li>
 
-If someone needs help getting the Ghostscript files (because they
 
-have a slow modem or no FTP access), we will sometimes refer them to a
 
-nearby user from this list.  In this case, we give them only the name, city,
 
-and e-mail address.
 
-</ul>
 
-
 
-<ul><li>
 
-One of the documentation files included with Ghostscript includes a
 
-thank-you for all the people who have helped develop and test it.
 
-</ul>
 
-
 
-<p>
 
-If you prefer that we not use your name even in these ways, please let us know.
 
-
 
-<p>
 
-If you are interested in testing Ghostscript on the Macintosh platform,
 
-please mail the completed questionnaire to <a
 
-href="mailto:mac-gs-beta-request@aladdin.com">mac-gs-test-request@aladdin.com</a>.
 
-If you are interested in testing Ghostscript on platforms other than the
 
-Macintosh, please mail the completed questionnaire to <a
 
-href="mailto:gs-test-request@aladdin.com">gs-test-request@aladdin.com</a>.
 
-(Of course, you can mail it to both places if appropriate.)

-href="http://www.cs.wisc.edu/~ghost/doc/AFPL/tester.htm"
 
-class="offsite">http://www.cs.wisc.edu/~ghost/doc/AFPL/tester.htm</a>, where they can find
 
-out about getting these filesets.

-<p>
 
-Thanks again for being willing to help improve Ghostscript.

-ICC profile I/O library (icclib), README file
 
----------------------------------------------
 
-
 
-Date 99/11/29, Version 1.23
 
-
 
-This distribution contains source code which implements the reading and
 
-writing of color profile files that conform to the International Color
 
-Consortium (ICC) Profile Format Specification, Version 3.4.
 
-
 
-For more information about the ICC, and for copies of the specification,
 
-please refer to http://www.color.org/.
 
-
 
-(Note that this software is written from the ICC V3.4 standard, but the
 
-software and its author are not affiliated with, or otherwise connected
 
-with the ICC.)
 
-
 
-The ICC profile I/O library archive is kept at
 
-http://web.access.net.au/argyll/color.html
 
-
 
-Motivation
 
-
 
-Color is still very much a black art to many programmers dealing with
 
-computer graphics. The ICC Profile Format is an industry attempt to provide
 
-an interchange format to help solve the problems of specifying color, and
 
-in transferring color graphics from, and between systems and devices.
 
-Although the ICC format has been around a number of years, and has long
 
-been adopted by companies in the business of providing systems for
 
-publishing and printing, and is now widely used as part of commercial
 
-operating system support for device independent color, its uptake in the
 
-general world of computer graphics has been slow.
 
-
 
-The writing of this library was prompted by my private and professional
 
-enthusiasm for computer graphics, and color. Inspired by other examples of
 
-freely usable software (notably the Independent JPEG Group's free JPEG
 
-software, and Sam Leffler's TIFF library), I have decided to make this
 
-library available under similar terms.  I hope that this library will
 
-provide a starting point for including ICC profile support more widely that
 
-is currently the case, particularly in open source code projects.
 
-
 
-Overview
 
-
 
-This package contains a C software implementation of the ICC Profile
 
-Format, Version 3.4. The ICC Profile Format attempts to provide a
 
-cross-platform device profile format, that can be used to translate color
 
-data created on one device into another device's native color space. For a
 
-fuller explanation of what the ICC Profile Format is all about, please
 
-refer to http://www.color.org, and the profile specification.
 
-
 
-In summary this library provides:
 
-
 
-   * Full source code, free for commercial and non-commercial use.
 
-   * Support for all version 3.4 header elements, Tags and Tag Types.
 
-   * Conversion to/from machine native representation of all data
 
-     types.
 
-   * Support for user defined Tags.
 
-   * Support for adding/deleting Tags.
 
-   * Support for Tag type sharing within a file (often used for
 
-     sharing LUTs amongst intents).
 
-   * Support for reading/writing embedded profiles.
 
-   * Provides a single function for transforming color values through
 
-     a profile, including support for intents, forward and reverse
 
-     transforms, gamut lookup or preview lookup.
 
-   * Provides support and code examples for creating all profile
 
-     types, monochrome, matrix and Lut.
 
-   * Attempts to be platform neutral.
 
-   * Loads Tag Types on demand to conserve memory space.
 
-
 
-Changes from V1.01
 
-
 
-Major changes since version 1.01 are the addition of the profile color
 
-lookup function, and Lut set_tables support function. The library has also
 
-benefited from many minor bug fixes and enhancements. Special thanks to
 
-Tsutomu Okuno and Yasuhiko Kiuchi for pointing out some subtle bugs in the
 
-code, which I hope now are fixed.
 
-
 
-Changes from V1.20
 
-
 
-A minor change was made to Lab encoding and default scaling of Lut style
 
-profiles, to bring it into line with recommended practice as described in
 
-Michael Bourgoin's 1998 SIGGRAPH course notes. Only icc.c and lutest.c have
 
-been altered.
 
-
 
-Changes from V1.21
 
-
 
-Some endian bugs in the Unicode read/write routines have been corrected, as
 
-well as improving the codes portability to some older SUN systems. The
 
-TextDescription dump() method now dumps Unicode and ScriptCode in Hex.
 
-Simplex (i.e. tetrahedral in 3D) interpolation is now used where
 
-appropriate for clut interpolation. The ICC.1:1998-09 include file is now
 
-being used, but the DeviceSettings and OutputResponse tags are still not
 
-supported.
 
-Added more hooks to support inherited implimentation of color conversion,
 
-used in Argyll to support reversing multi-dimentional table lookups.
 
-
 
-Changes from V1.22
 
-
 
-Fixed important bug in Lut read/write. The matrix values had their
 
-rows and columns switched. Not many profiles exercise this code.
 
-Thanks to David Gillman for discovering this.
 
-Fixup compiler complains about illegal enum values for icmCurveStyle,
 
-and icmDataStyle. Malloc memory icmLut_lookup_clut_nl for gw[], so that
 
-it is more friendly to systems with a limited stack. (Thanks to Dave White)
 
-
 
-Package contents:
 
-
 
- icclib.zipZIP archive of the following files
 
- README    This file.
 
- COPYRIGHT Important! - Permissions for use of this package.
 
- icc.c     Library source file.
 
-
 
- icc.h     Library include file. Note machine dependent defines. Includes
 
-           icc9809.h.
 
- icc9809.h Lightly modified standard ICC header file.
 
- iccdump.c Program that dumps ASCII description of a profile.
 
-
 
- icclu.c   Program that allows interactive or batch translation of color
 
-           values though a profile.
 
- icctest.c Basic library tag Read/Write example and regression test code.
 
-
 
- lutest.c  Color lookup regression test code, and example for creating
 
-           color profiles.
 
- iccrw.c   Source code skeleton for reading and then re-writing a profile.
 
- jamfile   JAM style "makefile" see http://www.perforce.com/jam/jam.html
 
- makefile  UNIX style makefile. Modify this to suite your system.
 
-
 
-
 
-Style
 
-
 
-For handling convenience, I have included all the library source code in
 
-two files. The down side is that they are both hard to read and navigate
 
-through. The code could do with some cleaning up and rearrangement, to make
 
-clear the distinction between public and private elements. (C++ would help
 
-here, but is less portable.) The code attempts to be ANSI C compliant,
 
-written in an object oriented style. Unfortunately, it has not been tested
 
-on a wide variety of platforms, nor with a very wide set of color profiles,
 
-so there my well be a number of bugs to discover. A tutorial on how to use
 
-the library would also be a good thing !
 
-
 
-The best way to learn how to use the library, is to take a look at
 
-icctest.c, lutest.c and iccrw.c. The first is used to test writing and
 
-reading to every type of element, with every possible variation of usage.
 
-You will need a copy of the ICC spec. handy to understand what it all
 
-means. The second source file specifically creates and then tests various
 
-types of profiles, including monochrome, matrix and Lut style profiles. The
 
-last is a source code skeleton, that reads a profile completely into
 
-memory, and then writes it out again to a different file.
 
-
 
-With the release of version 1.23 of icclib, the library is now as useful as
 
-it is likely to be, allowing convenient color conversion between PCS
 
-(profile connection spaces, either XYZ or Lab) and device specific color
 
-spaces. The library does not attempt to be a complete color management
 
-system however, lacking profile creation and linking functionality.
 
-
 
-I welcome feedback, positive or negative, so please mail me at

-		    GHOSTSCRIPT GENERAL PUBLIC LICENSE
 
-		    (Clarified 11 Feb 1988)
 
-
 
- Copyright (C) 1988 Richard M. Stallman
 
- Everyone is permitted to copy and distribute verbatim copies of this
 
- license, but changing it is not allowed.  You can also use this wording
 
- to make the terms for other programs.
 
-
 
-  The license agreements of most software companies keep you at the
 
-mercy of those companies.  By contrast, our general public license is
 
-intended to give everyone the right to share Ghostscript.  To make sure
 
-that you get the rights we want you to have, we need to make
 
-restrictions that forbid anyone to deny you these rights or to ask you
 
-to surrender the rights.  Hence this license agreement.
 
-
 
-  Specifically, we want to make sure that you have the right to give
 
-away copies of Ghostscript, that you receive source code or else can get
 
-it if you want it, that you can change Ghostscript or use pieces of it
 
-in new free programs, and that you know you can do these things.
 
-
 
-  To make sure that everyone has such rights, we have to forbid you to
 
-deprive anyone else of these rights.  For example, if you distribute
 
-copies of Ghostscript, 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 tell them their rights.
 
-
 
-  Also, for our own protection, we must make certain that everyone finds
 
-out that there is no warranty for Ghostscript.  If Ghostscript is
 
-modified by someone else and passed on, we want its recipients to know
 
-that what they have is not what we distributed, so that any problems
 
-introduced by others will not reflect on our reputation.
 
-
 
-  Therefore we (Richard M. Stallman and the Free Software Foundation,
 
-Inc.) make the following terms which say what you must do to be allowed
 
-to distribute or change Ghostscript.
 
-
 
-
 
-			COPYING POLICIES
 
-
 
-  1. You may copy and distribute verbatim copies of Ghostscript source
 
-code as you receive it, in any medium, provided that you conspicuously
 
-and appropriately publish on each copy a valid copyright and license
 
-notice "Copyright (C) 1989 Aladdin Enterprises.  All rights reserved.
 
-Distributed by Free Software Foundation, Inc." (or with whatever year is
 
-appropriate); keep intact the notices on all files that refer to this
 
-License Agreement and to the absence of any warranty; and give any other
 
-recipients of the Ghostscript program a copy of this License Agreement
 
-along with the program.  You may charge a distribution fee for the
 
-physical act of transferring a copy.
 
-
 
-  2. You may modify your copy or copies of Ghostscript or any portion of
 
-it, and copy and distribute such modifications under the terms of
 
-Paragraph 1 above, provided that you also do the following:
 
-
 
-    a) cause the modified files to carry prominent notices stating
 
-    that you changed the files and the date of any change; and
 
-
 
-    b) cause the whole of any work that you distribute or publish,
 
-    that in whole or in part contains or is a derivative of Ghostscript
 
-    or any part thereof, to be licensed at no charge to all third
 
-    parties on terms identical to those contained in this License
 
-    Agreement (except that you may choose to grant more extensive
 
-    warranty protection to some or all third parties, at your option).
 
-
 
-    c) You may charge a distribution fee for the physical act of
 
-    transferring a copy, and you may at your option offer warranty
 
-    protection in exchange for a fee.
 
-
 
-Mere aggregation of another unrelated program with this program (or its
 
-derivative) on a volume of a storage or distribution medium does not bring
 
-the other program under the scope of these terms.
 
-
 
-  3. You may copy and distribute Ghostscript (or a portion or derivative
 
-of it, under Paragraph 2) in object code or executable form under the
 
-terms of Paragraphs 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
 
-    Paragraphs 1 and 2 above; or,
 
-
 
-    b) accompany it with a written offer, valid for at least three
 
-    years, to give any third party free (except for a nominal
 
-    shipping charge) a complete machine-readable copy of the
 
-    corresponding source code, to be distributed under the terms of
 
-    Paragraphs 1 and 2 above; or,
 
-
 
-    c) accompany it with the information you received as to where the
 
-    corresponding source code may be obtained.  (This alternative is
 
-    allowed only for noncommercial distribution and only if you
 
-    received the program in object code or executable form alone.)
 
-
 
-For an executable file, complete source code means all the source code for
 
-all modules it contains; but, as a special exception, it need not include
 
-source code for modules which are standard libraries that accompany the
 
-operating system on which the executable file runs.
 
-
 
-  4. You may not copy, sublicense, distribute or transfer Ghostscript
 
-except as expressly provided under this License Agreement.  Any attempt
 
-otherwise to copy, sublicense, distribute or transfer Ghostscript is
 
-void and your rights to use the program under this License agreement
 
-shall be automatically terminated.  However, parties who have received
 
-computer software programs from you with this License Agreement will not
 
-have their licenses terminated so long as such parties remain in full
 
-compliance.
 
-
 
-  5. If you wish to incorporate parts of Ghostscript into other free
 
-programs whose distribution conditions are different, write to the Free
 
-Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not
 
-yet worked out a simple rule that can be stated here, but we will often
 
-permit this.  We will be guided by the two goals of preserving the free
 
-status of all derivatives of our free software and of promoting the
 
-sharing and reuse of software.
 
-
 
-Your comments and suggestions about our licensing policies and our
 
-software are welcome!  Please contact the Free Software Foundation,
 
-Inc., 675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.
 
-
 
-		       NO WARRANTY
 
-
 
-  BECAUSE GHOSTSCRIPT IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY
 
-NO WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW.  EXCEPT
 
-WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC, RICHARD
 
-M. STALLMAN, ALADDIN ENTERPRISES, L. PETER DEUTSCH, AND/OR OTHER PARTIES
 
-PROVIDE GHOSTSCRIPT "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
 
-EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
 
-WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE
 
-ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF GHOSTSCRIPT IS WITH
 
-YOU.  SHOULD GHOSTSCRIPT PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
 
-NECESSARY SERVICING, REPAIR OR CORRECTION.
 
-
 
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
 
-STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., L. PETER DEUTSCH, ALADDIN
 
-ENTERPRISES, AND/OR ANY OTHER PARTY WHO MAY MODIFY AND REDISTRIBUTE
 
-GHOSTSCRIPT AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
 
-ANY LOST PROFITS, LOST MONIES, OR OTHER SPECIAL, INCIDENTAL OR
 
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
 
-(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
 
-INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A FAILURE OF THE
 
-PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GHOSTSCRIPT, EVEN IF YOU
 
-HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM
 
-BY ANY OTHER PARTY.

+.SH NAME
 
+png \- Portable Network Graphics (PNG) format
 
+.SH DESCRIPTION
 
+PNG (Portable Network Graphics) is an extensible file format for the
 
+lossless, portable, well-compressed storage of raster images. PNG provides
 
+a patent-free replacement for GIF and can also replace many
 
+common uses of TIFF. Indexed-color, grayscale, and truecolor images are
 
+supported, plus an optional alpha channel. Sample depths range from
 
+1 to 16 bits.
 
+.br
 
+
 
+PNG is designed to work well in online viewing applications, such as the
 
+World Wide Web, so it is fully streamable with a progressive display
 
+option. PNG is robust, providing both full file integrity checking and
 
+fast, simple detection of common transmission errors. Also, PNG can store
 
+gamma and chromaticity data for improved color matching on heterogeneous
 
+platforms.

-.TH ANSI2KNR 1 "8 March 2000" \" -*- nroff -*-
 
-.SH NAME
 
-ansi2knr \- convert ANSI C to Kernighan & Ritchie C
 
-.SH SYNOPSIS
 
-\fBansi2knr\fR [\fB--filename\fR \fIfilename\fR] [\fIinput_file\fR [\fIoutput_file\fR]]
 
-.br
 
-.SH DESCRIPTION
 
-\fB--filename\fR provides the file name for the #line directive in the output,
 
-overriding \fIinput_file\fR (if present).
 
-.sp
 
-If no \fIinput_file\fR is supplied, input is read from stdin.
 
-.sp
 
-If no \fIoutput_file\fR is supplied, output goes to stdout.
 
-.sp
 
-There are no error messages.
 
-.sp
 
-\fBansi2knr\fR
 
-recognizes function definitions by seeing a non-keyword identifier at the left
 
-margin, followed by a left parenthesis, with a right parenthesis as the last
 
-character on the line, and with a left brace as the first token on the
 
-following line (ignoring possible intervening comments).  It will recognize a
 
-multi-line header provided that no intervening line ends with a left or right
 
-brace or a semicolon.  These algorithms ignore whitespace and comments, except
 
-that the function name must be the first thing on the line.
 
-.sp
 
-\fBansi2knr\fP
 
-also recognizes adjacent string literals and concatenates them.
 
-.sp
 
-The following constructs will confuse it:
 
-.br
 
-     - Any other construct that starts at the left margin and follows the
 
-above syntax (such as a macro or function call).
 
-.br
 
-     - Some macros that tinker with the syntax of the function header.
 
-.br
 
-     - String literals whose concatenation requires rewriting
 
-their contents; e.g. "ab\0" "07c" is concatenated to "ab\007c",
 
-which is not correct.
 
-.sp
 
-The --varargs switch is obsolete, and is recognized only for
 
-backwards compatibility.  The present version of
 
-\fBansi2knr\fR
 
-will always attempt to convert a ... argument to va_alist and va_dcl.
 
-.SH AUTHOR
 
-L. Peter Deutsch <ghost@aladdin.com> wrote the original ansi2knr and
 
-continues to maintain the current version; most of the code in the current
 
-version is his work.  ansi2knr also includes contributions by Francois
 
-Pinard <pinard@iro.umontreal.ca>, Jim Avera <jima@netcom.com>, and Paul
 
-Eggert <eggert@twinsun.com>.

-
 
-	lpd 2000-04-12 backs out Eggert's changes because of bugs:
 
-	- concatlits didn't declare the type of its bufend argument;
 
-	- concatlits didn't't recognize when it was inside a comment;
 
-	- scanstring could scan backward past the beginning of the string; when
 
-	- the check for \ + newline in scanstring was unnecessary.
 
-
 
-	2000-03-05  Paul Eggert  <eggert@twinsun.com>
 
-
 
-	Add support for concatenated string literals.
 
-	* ansi2knr.c (concatlits): New decl.
 
-	(main): Invoke concatlits to concatenate string literals.
 
-	(scanstring): Handle backslash-newline correctly.  Work with
 
-	character constants.  Fix bug when scanning backwards through
 
-	backslash-quote.  Check for unterminated strings.
 
-	(convert1): Parse character constants, too.
 
-	(appendline, concatlits): New functions.
 
-	* ansi2knr.1: Document this.
 
-
 
-	lpd 1999-08-17 added code to allow preprocessor directives
 
-		wherever comments are allowed
 
-	lpd 1999-04-12 added minor fixes from Pavel Roskin
 
-		<pavel_roskin@geocities.com> for clean compilation with
 
-		gcc -W -Wall
 
-	lpd 1999-03-22 added hack to recognize lines consisting of
 
-		identifier1(identifier2, xxx) as *not* being procedures
 
-	lpd 1999-02-03 made indentation of preprocessor commands consistent
 
-	lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
 
-		endless loop; quoted strings within an argument list
 
-		confused the parser
 
-	lpd 1999-01-24 added a check for write errors on the output,
 
-		suggested by Jim Meyering <meyering@ascend.com>
 
-	lpd 1998-11-09 added further hack to recognize identifier(void)
 
-		as being a procedure
 
-	lpd 1998-10-23 added hack to recognize lines consisting of
 
-		identifier1(identifier2) as *not* being procedures
 
-	lpd 1997-12-08 made input_file optional; only closes input and/or
 
-		output file if not stdin or stdout respectively; prints
 
-		usage message on stderr rather than stdout; adds
 
-		--filename switch (changes suggested by
 
-		<ceder@lysator.liu.se>)
 
-	lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
 
-		compilers that don't understand void, as suggested by
 
-		Tom Lane
 
-	lpd 1996-01-15 changed to require that the first non-comment token
 
-		on the line following a function header be a left brace,
 
-		to reduce sensitivity to macros, as suggested by Tom Lane
 
-		<tgl@sss.pgh.pa.us>
 
-	lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
 
-		undefined preprocessor symbols as 0; changed all #ifdefs
 
-		for configuration symbols to #ifs
 
-	lpd 1995-04-05 changed copyright notice to make it clear that
 
-		including ansi2knr in a program does not bring the entire
 
-		program under the GPL
 
-	lpd 1994-12-18 added conditionals for systems where ctype macros
 
-		don't handle 8-bit characters properly, suggested by
 
-		Francois Pinard <pinard@iro.umontreal.ca>;
 
-		removed --varargs switch (this is now the default)
 
-	lpd 1994-10-10 removed CONFIG_BROKETS conditional
 
-	lpd 1994-07-16 added some conditionals to help GNU `configure',
 
-		suggested by Francois Pinard <pinard@iro.umontreal.ca>;
 
-		properly erase prototype args in function parameters,
 
-		contributed by Jim Avera <jima@netcom.com>;
 
-		correct error in writeblanks (it shouldn't erase EOLs)

- * The PDF writer creates several different kinds of font resources.
 
- * The key differences between them are the values of num_chars, index,
 
- * and descriptor.
 
- *
 
- *	- Synthesized Type 3 bitmap fonts are identified by num_chars != 0 (or
 
- *	equivalently PDF_FONT_IS_SYNTHESIZED = true).  They have index < 0,
 
- *	FontDescriptor == 0.  All other fonts have num_chars == 0.
 
- *
 
- *	- Type 0 fonts have num_chars == 0, index < 0, FontDescriptor == 0.
 
- *	All other non-synthesized fonts have FontDescriptor != 0.
 
- *
 
- *	- The base 14 fonts (when not embedded) have num_chars == 0, index
 
- *	>= 0, FontDescriptor != 0, FontDescriptor->base_font == 0.  All
 
- *	other fonts have index < 0.
 
- *
 
- *	- All other fonts, embedded or not, have num_chars == 0, index < 0,
 
- *	FontDescriptor != 0, FontDescriptor->base_font != 0.  A font is
 
- *	embedded iff FontDescriptor->FontFile_id != 0.
 
- *
 
- * For non-synthesized fonts, the structure representation is designed to
 
- * represent directly the information that will be written in the font
 
- * resource, Encoding, and FontDescriptor dictionaries.  See the comments
 
- * on the pdf_font_t structure below for more detail.
 
- */
 
-
 
-/*
 
- * PDF font names must be large enough for the 14 built-in fonts,
 
- * and also large enough for any reasonable font name + 7 characters
 
- * for the subsetting prefix + a suffix derived from the PDF object number.

-/*
 
- * A FontDescriptor refers to an unscaled, possibly built-in base_font.
 
- * Multiple pdf_fonts with the same outlines (but possibly different
 
- * encodings, metrics, and scaling) may share a single FontDescriptor.
 
- * Each such pdf_font refers to a corresponding gs_font object, and
 
- * the gs_fonts of all such pdf_fonts will have the base_font of the
 
- * FontDescriptor as their eventual base font (through a chain of 0 or
 
- * more base pointers).
 
- *
 
- * Since gs_font objects may be freed at any time, we register a procedure
 
- * to be called when that happens.  The (gs_)font of a pdf_font may be freed
 
- * either before or after the base_font in the FontDescriptor.  Therefore, a
 
- * pdf_font copies enough information from its gs_font that when the gs_font
 
- * is freed, the pdf_font still has enough information to write the Font
 
- * resource dictionary at a later time.  When freeing a gs_font referenced
 
- * from a pdf_font, we only clear the pointer to it from its referencing
 
- * pdf_font.  However, when the base_font of a FontDescriptor is about to be
 
- * freed, we must write the FontDescriptor, and, if the font is embedded,
 
- * the FontFile data.

- * For a given character, check whether the encoding of bfont (the current
 
- * font) is compatible with that of the underlying unscaled, possibly
 
- * standard, base font, and if not, whether we can re-encode the character
 
- * using the base font's encoding.  Return the (possibly re-encoded)
 
- * character if successful.
 
- *
 
- * We have to handle re-encoded Type 1 fonts, because TeX output makes
 
- * constant use of them.  We have several alternatives for how to handle
 
- * characters whose encoding doesn't match their encoding in the base font's
 
- * built-in encoding.  If a character's glyph doesn't match the character's
 
- * glyph in the encoding built up so far, we check if the font has that
 
- * glyph at all; if not, we fall back to a bitmap.  Otherwise, we use one or
 
- * both of the following algorithms:
 
- *
 
- *      1. If this is the first time a character at this position has been
 
- *      seen, assign its glyph to that position in the encoding.
 
- *      We do this step if the device parameter ReAssignCharacters is true.
 
- *      (This is the default.)
 
- *
 
- *      2. If the glyph is present in the encoding at some other position,
 
- *      substitute that position for the character; otherwise, assign the
 
- *      glyph to an unoccupied (.notdef) position.
 
- *      We do this step if the device parameter ReEncodeCharacters is true.
 
- *      (This is the default.)
 
- *
 
- *      3. Finally, fall back to using a bitmap.
 
- *
 
- * If it is essential that all strings in the output contain exactly the
 
- * same character codes as the input, set ReEncodeCharacters to false.  If
 
- * it is important that strings be searchable, but some non-searchable
 
- * strings can be tolerated, the defaults are appropriate.  If searchability
 
- * is not important, set ReAssignCharacters to false.
 
- * 
- * Since the chars_used bit vector keeps track of characters by their
 
- * position in the Encoding, not by their glyph identifier, it can't record
 
- * use of unencoded characters.  Therefore, if we ever use an unencoded
 
- * character in an embedded font, we force writing the entire font rather
 
- * than a subset.  This is inelegant but (for the moment) too awkward to
 
- * fix.
 
- *
 
- * Acrobat Reader 3's Print function has a bug that make re-encoded
 
- * characters print as blank if the font is substituted (not embedded or one
 
- * of the base 14).  To work around this bug, when CompatibilityLevel <= 1.2,
 
- * for non-embedded non-base fonts, no substitutions or re-encodings are
 
- * allowed.

- *    Color dithering for Ghostscript.  The underlying device imaging model
 
- *      supports dithering between two colors to generate intermediate shades.
 
- *      
- *      If the device has high quality colors (at least 32 values
 
- *      per axis), we ask it to map the color directly.
 
- *
 
- *      Otherwise, things are a bit more complicated.  If the device 
- *      supports N shades of each R, G and B independently, there are a total 
- *      of N*N*N colors.  These colors form a 3-D grid in a cubical color 
- *      space.  The following dithering technique works by locating the 
- *      color we want in this 3-D color grid and finding the eight colors 
- *      that surround it.  In the case of dithering into 8 colors with 1 
- *      bit for each red, green and blue, these eight colors will always 
- *      be the same.
 
- *
 
- *      Now we consider all possible diagonal paths between the eight colors
 
- *      and chose the path that runs closest to our desired color in 3-D
 
- *      color space.  There are 28 such paths.  Then we find the position
 
- *      on the path that is closest to our color.
 
- *
 
- *      The search is made faster by always reflecting our color into
 
- *      the bottom octant of the cube and comparing it to 7 paths.
 
- *      After the best path and the best position on that path are found,
 
- *      the results are reflected back into the original color space.
 
- *
 
- *      NOTE: This code has been tested for B/W and Color imaging with
 
- *      1, 2, 3 and 8 bits per component.

-/* ------ Alternate LZWEncode filter implementation ------ */
 
-
 
-/*
 
-
 
-   The encoded data stream produced by this implementation of the LZWEncode
 
-   filter consists of a sequence of 9-bit data elements.  These elements are
 
-   packed into bytes in big-endian order, e.g. the elements
 
-
 
-   100000000 001100001
 
-
 
-   occurring at the very beginning of the data stream would be packed into
 
-   bytes as
 
-
 
-   10000000 00011000 01......
 
-
 
-   The first bit of each data element is a control bit.  If the control bit is
 
-   0, the remaining 8 bits of the data element are a data byte.  If the control
 
-   bit is 1, the remaining 8 bits of the data element define a control
 
-   function:
 
-
 
-   1 00000000   synchronization mark, see below
 
-   1 00000001   end of data
 
-   1 xxxxxxxx   not used (all other values)
 
-
 
-   The synchronization mark occurs at the beginning of the data stream, and at
 
-   least once every 254 data bytes thereafter.
 
-
 
-   This format is derived from basic principles of data encoding (the use of a
 
-   separate flag bit to distinguish out-of-band control information from data
 
-   per se, and the use of a periodic synchronization mark to help verify the
 
-   validity of a data stream); it has no relationship to data compression.  It
 
-   is, however, compatible with LZW decompressors.  It produces output that is
 
-   approximately 9/8 times the size of the input.

-1. Compression algorithm (deflate)
 
-
 
-The deflation algorithm used by zlib (also zip and gzip) is a variation of
 
-LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
 
-the input data.  The second occurrence of a string is replaced by a
 
-pointer to the previous string, in the form of a pair (distance,
 
-length).  Distances are limited to 32K bytes, and lengths are limited
 
-to 258 bytes. When a string does not occur anywhere in the previous
 
-32K bytes, it is emitted as a sequence of literal bytes.  (In this
 
-description, `string' must be taken as an arbitrary sequence of bytes,
 
-and is not restricted to printable characters.)
 
-
 
-Literals or match lengths are compressed with one Huffman tree, and
 
-match distances are compressed with another tree. The trees are stored
 
-in a compact form at the start of each block. The blocks can have any
 
-size (except that the compressed data for one block must fit in
 
-available memory). A block is terminated when deflate() determines that
 
-it would be useful to start another block with fresh trees. (This is
 
-somewhat similar to the behavior of LZW-based _compress_.)
 
-
 
-Duplicated strings are found using a hash table. All input strings of
 
-length 3 are inserted in the hash table. A hash index is computed for
 
-the next 3 bytes. If the hash chain for this index is not empty, all
 
-strings in the chain are compared with the current input string, and
 
-the longest match is selected.
 
-
 
-The hash chains are searched starting with the most recent strings, to
 
-favor small distances and thus take advantage of the Huffman encoding.
 
-The hash chains are singly linked. There are no deletions from the
 
-hash chains, the algorithm simply discards matches that are too old.
 
-
 
-To avoid a worst-case situation, very long hash chains are arbitrarily
 
-truncated at a certain length, determined by a runtime option (level
 
-parameter of deflateInit). So deflate() does not always find the longest
 
-possible match but generally finds a match which is long enough.
 
-
 
-deflate() also defers the selection of matches with a lazy evaluation
 
-mechanism. After a match of length N has been found, deflate() searches for a
 
-longer match at the next input byte. If a longer match is found, the
 
-previous match is truncated to a length of one (thus producing a single
 
-literal byte) and the longer match is emitted afterwards.  Otherwise,
 
-the original match is kept, and the next match search is attempted only
 
-N steps later.
 
-
 
-The lazy match evaluation is also subject to a runtime parameter. If
 
-the current match is long enough, deflate() reduces the search for a longer
 
-match, thus speeding up the whole process. If compression ratio is more
 
-important than speed, deflate() attempts a complete second search even if
 
-the first match is already long enough.
 
-
 
-The lazy match evaluation is not performed for the fastest compression
 
-modes (level parameter 1 to 3). For these fast modes, new strings
 
-are inserted in the hash table only when no match was found, or
 
-when the match is not too long. This degrades the compression ratio
 
-but saves time since there are both fewer insertions and fewer searches.
 
-
 
-
 
-2. Decompression algorithm (inflate)
 
-
 
-The real question is, given a Huffman tree, how to decode fast.  The most
 
-important realization is that shorter codes are much more common than
 
-longer codes, so pay attention to decoding the short codes fast, and let
 
-the long codes take longer to decode.
 
-
 
-inflate() sets up a first level table that covers some number of bits of
 
-input less than the length of longest code.  It gets that many bits from the
 
-stream, and looks it up in the table.  The table will tell if the next
 
-code is that many bits or less and how many, and if it is, it will tell
 
-the value, else it will point to the next level table for which inflate()
 
-grabs more bits and tries to decode a longer code.
 
-
 
-How many bits to make the first lookup is a tradeoff between the time it
 
-takes to decode and the time it takes to build the table.  If building the
 
-table took no time (and if you had infinite memory), then there would only
 
-be a first level table to cover all the way to the longest code.  However,
 
-building the table ends up taking a lot longer for more bits since short
 
-codes are replicated many times in such a table.  What inflate() does is
 
-simply to make the number of bits in the first table a variable, and set it
 
-for the maximum speed.
 
-
 
-inflate() sends new trees relatively often, so it is possibly set for a
 
-smaller first level table than an application that has only one tree for
 
-all the data.  For inflate, which has 286 possible codes for the
 
-literal/length tree, the size of the first table is nine bits.  Also the
 
-distance trees have 30 possible values, and the size of the first table is
 
-six bits.  Note that for each of those cases, the table ended up one bit
 
-longer than the ``average'' code length, i.e. the code length of an
 
-approximately flat code which would be a little more than eight bits for
 
-286 symbols and a little less than five bits for 30 symbols.  It would be
 
-interesting to see if optimizing the first level table for other
 
-applications gave values within a bit or two of the flat code size.

-   Notes beyond the 1.93a appnote.txt:
 
-
 
-   1. Distance pointers never point before the beginning of the output
 
-      stream.
 
-   2. Distance pointers can point back across blocks, up to 32k away.
 
-   3. There is an implied maximum of 7 bits for the bit length table and
 
-      15 bits for the actual data.
 
-   4. If only one code exists, then it is encoded using one bit.  (Zero
 
-      would be more efficient, but perhaps a little confusing.)  If two
 
-      codes exist, they are coded using one bit each (0 and 1).
 
-   5. There is no way of sending zero distance codes--a dummy must be
 
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
 
-      store blocks with no distance codes, but this was discovered to be
 
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
 
-      zero distance codes, which is sent as one code of zero bits in
 
-      length.
 
-   6. There are up to 286 literal/length codes.  Code 256 represents the
 
-      end-of-block.  Note however that the static length tree defines
 
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
 
-      cannot be used though, since there is no length base or extra bits
 
-      defined for them.  Similarily, there are up to 30 distance codes.
 
-      However, static trees define 32 codes (all 5 bits) to fill out the
 
-      Huffman codes, but the last two had better not show up in the data.
 
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
 
-      The exception is that a single code would not be complete (see #4).
 
-   8. The five bits following the block type is really the number of
 
-      literal codes sent minus 257.
 
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
 
-      (1+6+6).  Therefore, to output three times the length, you output
 
-      three codes (1+1+1), whereas to output four times the same length,
 
-      you only need two codes (1+3).  Hmm.
 
-  10. In the tree reconstruction algorithm, Code = Code + Increment
 
-      only if BitLength(i) is not zero.  (Pretty obvious.)
 
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
 
-  12. Note: length code 284 can represent 227-258, but length code 285
 
-      really is 258.  The last length deserves its own, short code
 
-      since it gets used a lot in very redundant files.  The length
 
-      258 is special since 258 - 3 (the min match length) is 255.
 
-  13. The literal/length and distance code bit lengths are read as a
 
-      single stream of lengths.  It is possible (and advantageous) for
 
-      a repeat code (16, 17, or 18) to go across the boundary between
 
-      the two sets of lengths.
