As for other library dependencies, source and binaries are no longer included but must be installed separately. The file layout has changed in one detail: zlib headers are now under XPlatform/zlib rather than XPlatform/zlib/inc. Rather than working around that by moving the headers after the build, I've updated those projects relying on that that I could find, hope it doesn't upset any that are not here. Installation instructions: 1. Download zlib126.zip (or a newer version) from http://www.zlib.net/ , extract the zlib-1.2.6 folder it contains and move/rename it to MOULOpenSourceClientPlugin/StaticSDKs/XPlatform/zlib . 2. Download lpng1510.zip (or a newer version) from http://libpng.org/pub/png/libpng.html , extract the lpng1510 folder it contains and move/rename it to MOULOpenSourceClientPlugin/StaticSDKs/XPlatform/png . 3. Open png/projects/visualc71/libpng.sln in Visual Studio 2003. 4. Select "LIB Debug" from the Solution Configurations popup menu in the toolbar, then Build > Build Solution. 5. Select the "LIB Release" configuration and build the solution. 6. Make a new folder png/lib and move png/projects/visualc71/Win32_LIB_Debug/libpngd.lib as well as png/projects/visualc71/Win32_LIB_Release/libpng.lib into it. 7. Make a new folder zlib/lib and move png/projects/visualc71/Win32_LIB_Debug/ZLib/zlibd.lib as well as png/projects/visualc71/Win32_LIB_Release/ZLib/zlib.lib into it.

Libpng 1.2.1 - December 12, 2001 |
||||
|
||||
This is a public release of libpng, intended for use in production codes. |
||||
|
||||
Changes since the last public release (1.2.0): |
||||
|
||||
Revised makefile.std in contrib/pngminus |
||||
Include background_1 in png_struct regardless of gamma support. |
||||
Revised makefile.netbsd and makefile.macosx, added makefile.darwin. |
||||
Revised example.c to provide more details about using row_callback(). |
||||
Added makefile.so9. |
||||
Removed type casts from all NULLs, except for those appearing in function |
||||
calls when PNG_NO_TYPECAST_NULL is defined. |
||||
Simplified png_create_info_struct() and png_creat_struct_2(). |
||||
Added error message if png_write_info() was omitted. |
||||
Changed typecast of "size" argument to png_size_t in pngmem.c calls to |
||||
the user malloc_fn, to agree with the prototype in png.h |
||||
Added a pop/push operation to pnggccrd.c, to preserve Eflag (Maxim Sobolev) |
||||
Updated makefile.sgi to recognize LIBPATH and INCPATH. |
||||
Updated various makefiles so "make clean" does not remove previous major |
||||
version of the shared library. |
||||
Added a pop/push operation to pngvcrd.c, to preserve Eflag. |
||||
Always allocate 256-entry internal palette, hist, and trans arrays, to |
||||
avoid out-of-bounds memory reference caused by invalid PNG datastreams. |
||||
Added a check for prefix_length > data_length in iCCP chunk handler. |

Installing libpng version 1.2.1 - December 12, 2001 |
||||
|
||||
Before installing libpng, you must first install zlib. zlib |
||||
can usually be found wherever you got libpng. zlib can be |
||||
placed in another directory, at the same level as libpng. |
||||
Note that your system might already have a preinstalled |
||||
zlib, but you will still need to have access to the |
||||
zlib.h and zconf.h include files that correspond to the |
||||
version of zlib that's installed. |
||||
|
||||
You can rename the directories that you downloaded (they |
||||
might be called "libpng-1.2.1" or "lpng109" and "zlib-1.1.3" |
||||
or "zlib113") so that you have directories called "zlib" and "libpng". |
||||
|
||||
Your directory structure should look like this: |
||||
|
||||
.. (the parent directory) |
||||
libpng (this directory) |
||||
INSTALL (this file) |
||||
README |
||||
*.h |
||||
*.c |
||||
contrib |
||||
gregbook |
||||
msvctest |
||||
pngminus |
||||
pngsuite |
||||
visupng |
||||
projects |
||||
beos |
||||
borland |
||||
msvc |
||||
netware.txt |
||||
wince.txt |
||||
scripts |
||||
makefile.* |
||||
pngtest.png |
||||
etc. |
||||
zlib |
||||
README |
||||
*.h |
||||
*.c |
||||
contrib |
||||
etc. |
||||
|
||||
If the line endings in the files look funny, you may wish to get the other |
||||
distribution of libpng. It is available in both tar.gz (UNIX style line |
||||
endings) and zip (DOS style line endings) formats. |
||||
|
||||
If you are building libpng with MSVC, you can enter the libpng\msvc directory |
||||
and follow the instructions in msvc\README.txt. |
||||
|
||||
You can build libpng for WindowsCE by entering the downloading and installing |
||||
the libpng\wince directory as instructed in the projects\wince.txt file, and |
||||
then following the instructions in the README* files. Similarly, you can |
||||
build libpng for Netware as instructed in projects\netware.txt. |
||||
|
||||
Else enter the zlib directory and follow the instructions in zlib/README, |
||||
then come back here and choose the appropriate makefile.sys in the scripts |
||||
directory. |
||||
|
||||

||||
include |
||||

||||
SCOPTIONS.ppc => Used with smakefile.ppc |
||||
|
||||
Copy the file (or files) that you need from the |
||||
scripts directory into this directory, for example |
||||
|
||||
MSDOS example: copy scripts\makefile.msc makefile |
||||
UNIX example: cp scripts/makefile.std makefile |
||||
|
||||
Read the makefile to see if you need to change any source or |
||||
target directories to match your preferences. |
||||
|
||||
Then read pngconf.h to see if you want to make any configuration |
||||
changes. |
||||
|
||||
Then just run "make test" which will create the libpng library in |
||||
this directory and run a quick test that reads the "pngtest.png" |
||||
file and writes a "pngout.png" file that should be identical to it. |
||||
Look for "9782 zero samples" in the output of the test. For more |
||||
confidence, you can run another test by typing "pngtest pngnow.png" |
||||
and looking for "289 zero samples" in the output. Also, you can |
||||
run "pngtest -m *.png" in the "contrib/pngsuite" directory and compare |
||||
your output with the result shown in contrib/pngsuite/README. |
||||
|
||||
Most of the makefiles will allow you to run "make install" to |
||||
put the library in its final resting place (if you want to |
||||
do that, run "make install" in the zlib directory first if necessary). |
||||
|
||||
Further information can be found in the README and libpng.txt |
||||
files, in the individual makefiles, in png.h, in the README files in |
||||
subdirectories of the LIB directory, and the manual pages libpng.3 and png.5. |

README for libpng 1.2.1 - December 12, 2001 (shared library 2.1) |
||||
See the note about version numbers near the top of png.h |
||||
|
||||
See INSTALL for instructions on how to install libpng. |
||||
|
||||
Libpng comes in two distribution formats. Get libpng-*.tar.gz if you |
||||
want UNIX-style line endings in the text files, or lpng*.zip if you want |
||||
DOS-style line endings. |
||||
|
||||
Version 0.89 was the first official release of libpng. Don't let the |
||||
fact that it's the first release fool you. The libpng library has been in |
||||
extensive use and testing since mid-1995. By late 1997 it had |
||||
finally gotten to the stage where there hadn't been significant |
||||
changes to the API in some time, and people have a bad feeling about |
||||
libraries with versions < 1.0. Version 1.0.0 was released in |
||||
March 1998. |
||||
|
||||
**** |
||||
Note that some of the changes to the png_info structure render this |
||||
version of the library binary incompatible with libpng-0.89 or |
||||
earlier versions if you are using a shared library. The type of the |
||||
"filler" parameter for png_set_filler() has changed from png_byte to |
||||
png_uint_32, which will affect shared-library applications that use |
||||
this function. |
||||
|
||||
To avoid problems with changes to the internals of png_info_struct, |
||||
new APIs have been made available in 0.95 to avoid direct application |
||||
access to info_ptr. These functions are the png_set_<chunk> and |
||||
png_get_<chunk> functions. These functions should be used when |
||||
accessing/storing the info_struct data, rather than manipulating it |
||||
directly, to avoid such problems in the future. |
||||
|
||||
It is important to note that the APIs do not make current programs |
||||
that access the info struct directly incompatible with the new |
||||
library. However, it is strongly suggested that new programs use |
||||
the new APIs (as shown in example.c and pngtest.c), and older programs |
||||
be converted to the new format, to facilitate upgrades in the future. |
||||
**** |
||||
|
||||
Additions since 0.90 include the ability to compile libpng as a |
||||
Windows DLL, and new APIs for accessing data in the info struct. |
||||
Experimental functions include the ability to set weighting and cost |
||||
factors for row filter selection, direct reads of integers from buffers |
||||
on big-endian processors that support misaligned data access, faster |
||||
methods of doing alpha composition, and more accurate 16->8 bit color |
||||
conversion. |
||||
|
||||
The additions since 0.89 include the ability to read from a PNG stream |
||||
which has had some (or all) of the signature bytes read by the calling |
||||
application. This also allows the reading of embedded PNG streams that |
||||
do not have the PNG file signature. As well, it is now possible to set |
||||
the library action on the detection of chunk CRC errors. It is possible |
||||
to set different actions based on whether the CRC error occurred in a |
||||
critical or an ancillary chunk. |
||||
|
||||
The changes made to the library, and bugs fixed are based on discussions |
||||
on the PNG implementation mailing list <png-implement@ccrc.wustl.edu> |
||||
and not on material submitted privately to Guy, Andreas, or Glenn. They will |
||||
forward any good suggestions to the list. |
||||
|
||||
For a detailed description on using libpng, read libpng.txt. For |
||||
examples of libpng in a program, see example.c and pngtest.c. For usage |
||||
information and restrictions (what little they are) on libpng, see |
||||
png.h. For a description on using zlib (the compression library used by |
||||
libpng) and zlib's restrictions, see zlib.h |
||||
|
||||
I have included a general makefile, as well as several machine and |
||||
compiler specific ones, but you may have to modify one for your own needs. |
||||
|
||||
You should use zlib 1.0.4 or later to run this, but it MAY work with |
||||
versions as old as zlib 0.95. Even so, there are bugs in older zlib |
||||
versions which can cause the output of invalid compression streams for |
||||
some images. You will definitely need zlib 1.0.4 or later if you are |
||||
taking advantage of the MS-DOS "far" structure allocation for the small |
||||
and medium memory models. You should also note that zlib is a |
||||
compression library that is useful for more things than just PNG files. |
||||
You can use zlib as a drop-in replacement for fread() and fwrite() if |
||||
you are so inclined. |
||||
|
||||
zlib should be available at the same place that libpng is. |
||||
If not, it should be at ftp.uu.net in /graphics/png |
||||
Eventually, it will be at ftp.uu.net in /pub/archiving/zip/zlib |
||||
|
||||
You may also want a copy of the PNG specification. It is available |
||||
as an RFC and a W3C Recommendation. Failing |
||||
these resources you can try ftp.uu.net in the /graphics/png directory. |
||||
|
||||
This code is currently being archived at ftp.uu.net in the |
||||
/graphics/png directory, and on CompuServe, Lib 20 (PNG SUPPORT) |
||||
at GO GRAPHSUP. If you can't find it in any of those places, |
||||
e-mail me, and I'll help you find it. |
||||
|
||||
If you have any code changes, requests, problems, etc., please e-mail |
||||
them to me. Also, I'd appreciate any make files or project files, |
||||
and any modifications you needed to make to get libpng to compile, |
||||
along with a #define variable to tell what compiler/system you are on. |
||||
If you needed to add transformations to libpng, or wish libpng would |
||||
provide the image in a different way, drop me a note (and code, if |
||||
possible), so I can consider supporting the transformation. |
||||
Finally, if you get any warning messages when compiling libpng |
||||
(note: not zlib), and they are easy to fix, I'd appreciate the |
||||
fix. Please mention "libpng" somewhere in the subject line. Thanks. |
||||
|
||||
This release was created and will be supported by myself (of course |
||||
based in a large way on Guy's and Andreas' earlier work), and the PNG group. |
||||
|
||||
randeg@alum.rpi.edu |
||||
png-implement@ccrc.wustl.edu |
||||
|
||||
You can't reach Guy, the original libpng author, at the addresses |
||||
given in previous versions of this document. He and Andreas will read mail |
||||
addressed to the png-implement list, however. |
||||
|
||||
Please do not send general questions about PNG. Send them to |
||||
the address in the specification (png-group@w3.org). At the same |
||||
time, please do not send libpng questions to that address, send them to me |
||||
or to png-implement@ccrc.wustl.edu. I'll |
||||
get them in the end anyway. If you have a question about something |
||||
in the PNG specification that is related to using libpng, send it |
||||
to me. Send me any questions that start with "I was using libpng, |
||||
and ...". If in doubt, send questions to me. I'll bounce them |
||||
to others, if necessary. |
||||
|
||||
Please do not send suggestions on how to change PNG. We have |
||||
been discussing PNG for three years now, and it is official and |
||||
finished. If you have suggestions for libpng, however, I'll |
||||
gladly listen. Even if your suggestion is not used for version |
||||
1.0, it may be used later. |

Text conversion between different code pages (Latin-1 -> Mac and DOS). |
||||
Should we always malloc 2^bit_depth PLTE/tRNS/hIST entries for safety? |
||||
Build gamma tables using fixed point (and do away with floating point entirely). |

background and doing rgb-to-gray transformation. |
||||
Investigate pre-incremented loop counters and other loop constructions. |

Y2K compliance in libpng: |
||||
========================= |
||||
|
||||
December 12, 2001 |
||||
|
||||
Since the PNG Development group is an ad-hoc body, we can't make |
||||
an official declaration. |
||||
|
||||
This is your unofficial assurance that libpng from version 0.71 and |
||||
upward through 1.2.1 are Y2K compliant. It is my belief that earlier |
||||
versions were also Y2K compliant. |
||||
|
||||
Libpng only has three year fields. One is a 2-byte unsigned integer |
||||
that will hold years up to 65535. The other two hold the date in text |
||||
format, and will hold years up to 9999. |
||||
|
||||
The integer is |
||||
"png_uint_16 year" in png_time_struct. |
||||
|
||||
The strings are |
||||
"png_charp time_buffer" in png_struct and |
||||
"near_time_buffer", which is a local character string in png.c. |
||||
|
||||
There are seven time-related functions: |
||||
|
||||
png_convert_to_rfc_1123() in png.c |
||||
(formerly png_convert_to_rfc_1152() in error) |
||||
png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c |
||||
png_convert_from_time_t() in pngwrite.c |
||||
png_get_tIME() in pngget.c |
||||
png_handle_tIME() in pngrutil.c, called in pngread.c |
||||
png_set_tIME() in pngset.c |
||||
png_write_tIME() in pngwutil.c, called in pngwrite.c |
||||
|
||||
All appear to handle dates properly in a Y2K environment. The |
||||
png_convert_from_time_t() function calls gmtime() to convert from system |
||||
clock time, which returns (year - 1900), which we properly convert to |
||||
the full 4-digit year. There is a possibility that applications using |
||||
libpng are not passing 4-digit years into the png_convert_to_rfc_1123() |
||||
function, or that they are incorrectly passing only a 2-digit year |
||||
instead of "year - 1900" into the png_convert_from_struct_tm() function, |
||||
but this is not under our control. The libpng documentation has always |
||||
stated that it works with 4-digit years, and the APIs have been |
||||
documented as such. |
||||
|
||||
The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned |
||||
integer to hold the year, and can hold years as large as 65535. |
||||
|
||||
zlib, upon which libpng depends, is also Y2K compliant. It contains |
||||
no date-related code. |

||||
. ZALLOC the value area for huft_build() instead of using stack |

||||
- added compress2() to allow setting the compression level |
||||
- include sys/types.h to get off_t on some systems (Marc Lehmann & QingLong) |
||||

||||
|
||||
Changes in 1.0.4 (24 Jul 96) |
||||
- In very rare conditions, deflate(s, Z_FINISH) could fail to produce an EOF |
||||
bit, so the decompressor could decompress all the correct data but went |
||||
on to attempt decompressing extra garbage data. This affected minigzip too. |
||||
- zlibVersion and gzerror return const char* (needed for DLL) |
||||

||||
|
||||
Changes in 1.0.3 (2 Jul 96) |
||||
- use z_streamp instead of z_stream *, which is now a far pointer in MSDOS |
||||
small and medium models; this makes the library incompatible with previous |
||||
versions for these models. (No effect in large model or on other systems.) |

||||
avail_out as zero but there is nothing to do |

||||
|
||||

||||
- added Windows DLL support |
||||
- added a function zlibVersion (for the DLL support) |
||||
- fixed declarations using Bytef in infutil.c (pb with MSDOS medium model) |
||||
- Bytef is define's instead of typedef'd only for Borland C |
||||
- avoid reading uninitialized memory in example.c |
||||
- mention in README that the zlib format is now RFC1950 |
||||
- updated Makefile.dj2 |
||||
- added algorithm.doc |
||||
|

||||
- added reference to Perl interface in README |
||||
- put the crc table in FAR data (I dislike more and more the medium model :) |
||||
- added get_crc_table |
||||
- added a dimension to all arrays (Borland C can't count). |
||||
- workaround Borland C bug in declaration of inflate_codes_new & inflate_fast |
||||
- guard against multiple inclusion of *.h (for precompiled header on Mac) |
||||
- Watcom C pretends to be Microsoft C small model even in 32 bit mode. |
||||
- don't use unsized arrays to avoid silly warnings by Visual C++: |
||||
warning C4746: 'inflate_mask' : unsized array treated as '__far' |
||||
(what's wrong with far data in far model?). |
||||
- define enum out of inflate_blocks_state to allow compilation with C++ |
||||
|
||||
Changes in 0.95 (16 Aug 95) |
||||
- fix MSDOS small and medium model (now easier to adapt to any compiler) |
||||
- inlined send_bits |
||||
- fix the final (:-) bug for deflate with flush (output was correct but |
||||
not completely flushed in rare occasions). |
||||
- default window size is same for compression and decompression |
||||
(it's now sufficient to set MAX_WBITS in zconf.h). |
||||
- voidp -> voidpf and voidnp -> voidp (for consistency with other |
||||
typedefs and because voidnp was not near in large model). |
||||
|
||||
Changes in 0.94 (13 Aug 95) |
||||
- support MSDOS medium model |
||||
- fix deflate with flush (could sometimes generate bad output) |
||||
- fix deflateReset (zlib header was incorrectly suppressed) |
||||
- added support for VMS |
||||
- allow a compression level in gzopen() |
||||
- gzflush now calls fflush |
||||
- For deflate with flush, flush even if no more input is provided. |
||||
- rename libgz.a as libz.a |
||||
- avoid complex expression in infcodes.c triggering Turbo C bug |
||||
- work around a problem with gcc on Alpha (in INSERT_STRING) |
||||
- don't use inline functions (problem with some gcc versions) |
||||
- allow renaming of Byte, uInt, etc... with #define. |
||||
- avoid warning about (unused) pointer before start of array in deflate.c |
||||
- avoid various warnings in gzio.c, example.c, infblock.c, adler32.c, zutil.c |
||||
- avoid reserved word 'new' in trees.c |
||||
|
||||
Changes in 0.93 (25 June 95) |
||||
- temporarily disable inline functions |
||||
- make deflate deterministic |
||||
- give enough lookahead for PARTIAL_FLUSH |
||||
- Set binary mode for stdin/stdout in minigzip.c for OS/2 |
||||
- don't even use signed char in inflate (not portable enough) |
||||
- fix inflate memory leak for segmented architectures |
||||
|
||||
Changes in 0.92 (3 May 95) |
||||
- don't assume that char is signed (problem on SGI) |
||||
- Clear bit buffer when starting a stored block |
||||
- no memcpy on Pyramid |
||||
- suppressed inftest.c |
||||
- optimized fill_window, put longest_match inline for gcc |
||||

- Default MEM_LEVEL is 8 (not 9 for Unix) as documented in zlib.h |
||||
- Document the memory requirements in zconf.h |
||||
- added "make install" |
||||
- fix sync search logic in inflateSync |
||||
- deflate(Z_FULL_FLUSH) now works even if output buffer too short |
||||
- after inflateSync, don't scare people with just "lo world" |
||||
- added support for DJGPP |
||||
|
||||
Changes in 0.9 (1 May 95) |
||||
- don't assume that zalloc clears the allocated memory (the TurboC bug |
||||
was Mark's bug after all :) |
||||
- let again gzread copy uncompressed data unchanged (was working in 0.71) |
||||
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented |
||||
- added a test of inflateSync in example.c |
||||
- moved MAX_WBITS to zconf.h because users might want to change that. |
||||
- document explicitly that zalloc(64K) on MSDOS must return a normalized |
||||
pointer (zero offset) |
||||
- added Makefiles for Microsoft C, Turbo C, Borland C++ |
||||
- faster crc32() |
||||
|
||||
Changes in 0.8 (29 April 95) |
||||
- added fast inflate (inffast.c) |
||||
- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this |
||||
is incompatible with previous versions of zlib which returned Z_OK. |
||||
- work around a TurboC compiler bug (bad code for b << 0, see infutil.h) |
||||
(actually that was not a compiler bug, see 0.81 above) |
||||
- gzread no longer reads one extra byte in certain cases |
||||
- In gzio destroy(), don't reference a freed structure |
||||
- avoid many warnings for MSDOS |
||||
- avoid the ERROR symbol which is used by MS Windows |
||||
|
||||
Changes in 0.71 (14 April 95) |

- Fixed more MSDOS compilation problems :( There is still a bug with |
||||
TurboC large model. |
||||
|
||||
Changes in 0.7 (14 April 95) |
||||
- Added full inflate support. |
||||
- Simplified the crc32() interface. The pre- and post-conditioning |
||||
(one's complement) is now done inside crc32(). WARNING: this is |
||||
incompatible with previous versions; see zlib.h for the new usage. |
||||
|
||||
Changes in 0.61 (12 April 95) |
||||
- workaround for a bug in TurboC. example and minigzip now work on MSDOS. |
||||
|
||||
Changes in 0.6 (11 April 95) |
||||
- added minigzip.c |
||||
- added gzdopen to reopen a file descriptor as gzFile |
||||
- added transparent reading of non-gziped files in gzread. |
||||

||||
- don't allocate big arrays in the stack (for MSDOS) |
||||
- fix some MSDOS compilation problems |
||||
|
||||
Changes in 0.5: |
||||
- do real compression in deflate.c. Z_PARTIAL_FLUSH is supported but |
||||
not yet Z_FULL_FLUSH. |
||||
- support decompression but only in a single step (forced Z_FINISH) |
||||
- added opaque object for zalloc and zfree. |
||||
- added deflateReset and inflateReset |
||||
- added a variable zlib_version for consistency checking. |
||||
- renamed the 'filter' parameter of deflateInit2 as 'strategy'. |
||||
Added Z_FILTERED and Z_HUFFMAN_ONLY constants. |
||||
|
||||
Changes in 0.4: |
||||
- avoid "zip" everywhere, use zlib instead of ziplib. |
||||
- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush |
||||
if compression method == 8. |
||||
- added adler32 and crc32 |
||||
- renamed deflateOptions as deflateInit2, call one or the other but not both |
||||
- added the method parameter for deflateInit2. |
||||
- added inflateInit2 |
||||
- simplied considerably deflateInit and inflateInit by not supporting |
||||
user-provided history buffer. This is supported only in deflateInit2 |
||||
and inflateInit2. |
||||
|
||||
Changes in 0.3: |
||||
- prefix all macro names with Z_ |
||||
- use Z_FINISH instead of deflateEnd to finish compression. |
||||
- added Z_HUFFMAN_ONLY |
||||
- added gzerror() |

Frequently Asked Questions about zlib |
||||
|
||||
|
||||
If your question is not there, please check the zlib home page |
||||
http://www.zlib.org which may have more recent information. |
||||
The lastest zlib FAQ is at http://www.gzip.org/zlib/zlib_faq.html |
||||
|
||||
|
||||
1. Is zlib Y2K-compliant? |
||||
|
||||
Yes. zlib doesn't handle dates. |
||||
|
||||
2. Where can I get a Windows DLL version? |
||||
|
||||
The zlib sources can be compiled without change to produce a DLL. If you |
||||
want a precompiled DLL, see http://www.winimage.com/zLibDll/ . Questions |
||||
about the zlib DLL should be sent to Gilles Vollant (info@winimage.com). |
||||
|
||||
3. Where can I get a Visual Basic interface to zlib? |
||||
|
||||
See |
||||
* http://www.winimage.com/zLibDll/cmp-z-it.zip |
||||
* http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm |
||||
* contrib/visual-basic.txt in the zlib distribution |
||||
|
||||
4. compress() returns Z_BUF_ERROR |
||||
|
||||
Make sure that before the call of compress, the length of the compressed |
||||
buffer is equal to the total size of the compressed buffer and not |
||||
zero. For Visual Basic, check that this parameter is passed by reference |
||||
("as any"), not by value ("as long"). |
||||
|
||||
5. deflate() or inflate() returns Z_BUF_ERROR |
||||
|
||||
Before making the call, make sure that avail_in and avail_out are not |
||||
zero. When setting the parameter flush equal to Z_FINISH, also make sure |
||||
that avail_out is big enough to allow processing all pending input. |
||||
|
||||
6. Where's the zlib documentation (man pages, etc.)? |
||||
|
||||
It's in zlib.h for the moment, and Francis S. Lin has converted it to a |
||||
web page zlib.html. Volunteers to transform this to Unix-style man pages, |
||||
please contact Jean-loup Gailly (jloup@gzip.org). Examples of zlib usage |
||||
are in the files example.c and minigzip.c. |
||||
|
||||
7. Why don't you use GNU autoconf or libtool or ...? |
||||
|
||||
Because we would like to keep zlib as a very small and simple |
||||
package. zlib is rather portable and doesn't need much configuration. |
||||
|
||||
8. I found a bug in zlib. |
||||
|
||||
Most of the time, such problems are due to an incorrect usage of |
||||
zlib. Please try to reproduce the problem with a small program and send |
||||
the corresponding source to us at zlib@gzip.org . Do not send |
||||
multi-megabyte data files without prior agreement. |
||||
|
||||
9. Why do I get "undefined reference to gzputc"? |
||||
|
||||
If "make test" produces something like |
||||
|
||||
example.o(.text+0x154): undefined reference to `gzputc' |
||||
|
||||
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or |
||||
/usr/X11R6/lib. Remove any old versions, then do "make install". |
||||
|
||||
10. I need a Delphi interface to zlib. |
||||
|
||||
See the directories contrib/delphi and contrib/delphi2 in the zlib |
||||
distribution. |
||||
|
||||
11. Can zlib handle .zip archives? |
||||
|
||||
See the directory contrib/minizip in the zlib distribution. |
||||
|
||||
12. Can zlib handle .Z files? |
||||
|
||||
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt |
||||
the code of uncompress on your own. |
||||
|
||||
13. How can I make a Unix shared library? |
||||
|
||||
make clean |
||||
./configure -s |
||||
make |
||||
|
||||
14. Why does "make test" fail on Mac OS X? |
||||
|
||||
Mac OS X already includes zlib as a shared library, and so -lz links the |
||||
shared library instead of the one that the "make" compiled. For zlib |
||||
1.1.3, the two are incompatible due to different compile-time |
||||
options. Simply change the -lz in the Makefile to libz.a, and it will use |
||||
the compiled library instead of the shared one and the "make test" will |
||||
succeed. |
||||
|
||||
15. I have a question about OttoPDF |
||||
|
||||
We are not the authors of OttoPDF. The real author is on the OttoPDF web |
||||
site Joel Hainley jhainley@myndkryme.com. |

zlib 1.1.4 is a general purpose data compression library. All the code |
||||
is thread safe. The data format used by the zlib library |
||||
is described by RFCs (Request for Comments) 1950 to 1952 in the files |
||||
http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate |
||||
format) and rfc1952.txt (gzip format). These documents are also available in |
||||
other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html |
||||
|
||||
All functions of the compression library are documented in the file zlib.h |
||||
(volunteer to write man pages welcome, contact jloup@gzip.org). A usage |
||||
example of the library is given in the file example.c which also tests that |
||||
the library is working correctly. Another example is given in the file |
||||
minigzip.c. The compression library itself is composed of all source files |
||||
except example.c and minigzip.c. |
||||
|
||||
To compile all files and run the test program, follow the instructions |
||||
given at the top of Makefile. In short "make test; make install" |
||||
should work for most machines. For Unix: "./configure; make test; make install" |
||||
For MSDOS, use one of the special makefiles such as Makefile.msc. |
||||
For VMS, use Make_vms.com or descrip.mms. |
||||
|
||||
Questions about zlib should be sent to <zlib@gzip.org>, or to |
||||
Gilles Vollant <info@winimage.com> for the Windows DLL version. |
||||
The zlib home page is http://www.zlib.org or http://www.gzip.org/zlib/ |
||||
Before reporting a problem, please check this site to verify that |
||||
you have the latest version of zlib; otherwise get the latest version and |
||||
check whether the problem still exists or not. |
||||
|
||||
PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html |
||||
before asking for help. |
||||
|

Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997 |
||||
issue of Dr. Dobb's Journal; a copy of the article is available in |
||||
http://dogma.net/markn/articles/zlibtool/zlibtool.htm |
||||
|
||||
The changes made in version 1.1.4 are documented in the file ChangeLog. |
||||
The only changes made since 1.1.3 are bug corrections: |
||||
|
||||
- ZFREE was repeated on same allocation on some error conditions. |
||||
This creates a security problem described in |
||||
http://www.zlib.org/advisory-2002-03-11.txt |
||||
- Returned incorrect error (Z_MEM_ERROR) on some invalid data |
||||
- Avoid accesses before window for invalid distances with inflate window |
||||
less than 32K. |
||||
- force windowBits > 8 to avoid a bug in the encoder for a window size |
||||
of 256 bytes. (A complete fix will be available in 1.1.5). |
||||
|
||||
The beta version 1.1.5beta includes many more changes. A new official |
||||
version 1.1.5 will be released as soon as extensive testing has been |
||||
completed on it. |

Notes for some targets: |
||||
|
||||
- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc |
||||
and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL |
||||
The zlib DLL support was initially done by Alessandro Iacopetti and is |
||||
now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL |
||||
home page at http://www.winimage.com/zLibDll |
||||
|
||||
From Visual Basic, you can call the DLL functions which do not take |
||||
a structure as argument: compress, uncompress and all gz* functions. |
||||
See contrib/visual-basic.txt for more information, or get |
||||

|
||||
- For 64-bit Irix, deflate.c must be compiled without any optimization. |
||||
With -O, one libpng test fails. The test works in 32 bit mode (with |
||||
the -n32 compiler flag). The compiler bug has been reported to SGI. |
||||
|
||||
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 |
||||
it works when compiled with cc. |
||||
|
||||
- on Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 |
||||
is necessary to get gzprintf working correctly. This is done by configure. |
||||
|
||||
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works |
||||
with other compilers. Use "make test" to check your compiler. |
||||
|
||||
- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers. |
||||
|
||||
- For Turbo C the small model is supported only with reduced performance to |
||||
avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3 |
||||
|
||||
- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html |

1. Compression algorithm (deflate) |
||||
|
||||
The deflation algorithm used by gzip (also zip and zlib) 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 process of lazy evaluation begins again. 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) |
||||
|
||||
2.1 Introduction |
||||
|
||||
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. |
||||
|
||||
|
||||
2.2 More details on the inflate table lookup |
||||
|
||||
Ok, you want to know what this cleverly obfuscated inflate tree actually |
||||
looks like. You are correct that it's not a Huffman tree. It is simply a |
||||
lookup table for the first, let's say, nine bits of a Huffman symbol. The |
||||
symbol could be as short as one bit or as long as 15 bits. If a particular |
||||
symbol is shorter than nine bits, then that symbol's translation is duplicated |
||||
in all those entries that start with that symbol's bits. For example, if the |
||||
symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a |
||||
symbol is nine bits long, it appears in the table once. |
||||
|
||||
If the symbol is longer than nine bits, then that entry in the table points |
||||
to another similar table for the remaining bits. Again, there are duplicated |
||||
entries as needed. The idea is that most of the time the symbol will be short |
||||
and there will only be one table look up. (That's whole idea behind data |
||||
compression in the first place.) For the less frequent long symbols, there |
||||
will be two lookups. If you had a compression method with really long |
||||
symbols, you could have as many levels of lookups as is efficient. For |
||||
inflate, two is enough. |
||||
|
||||
So a table entry either points to another table (in which case nine bits in |
||||
the above example are gobbled), or it contains the translation for the symbol |
||||
and the number of bits to gobble. Then you start again with the next |
||||
ungobbled bit. |
||||
|
||||
You may wonder: why not just have one lookup table for how ever many bits the |
||||
longest symbol is? The reason is that if you do that, you end up spending |
||||
more time filling in duplicate symbol entries than you do actually decoding. |
||||
At least for deflate's output that generates new trees every several 10's of |
||||
kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code |
||||
would take too long if you're only decoding several thousand symbols. At the |
||||
other extreme, you could make a new table for every bit in the code. In fact, |
||||
that's essentially a Huffman tree. But then you spend two much time |
||||
traversing the tree while decoding, even for short symbols. |
||||
|
||||
So the number of bits for the first lookup table is a trade of the time to |
||||
fill out the table vs. the time spent looking at the second level and above of |
||||
the table. |
||||
|
||||
Here is an example, scaled down: |
||||
|
||||
The code being decoded, with 10 symbols, from 1 to 6 bits long: |
||||
|
||||
A: 0 |
||||
B: 10 |
||||
C: 1100 |
||||
D: 11010 |
||||
E: 11011 |
||||
F: 11100 |
||||
G: 11101 |
||||
H: 11110 |
||||
I: 111110 |
||||
J: 111111 |
||||
|
||||
Let's make the first table three bits long (eight entries): |
||||
|
||||
000: A,1 |
||||
001: A,1 |
||||
010: A,1 |
||||
011: A,1 |
||||
100: B,2 |
||||
101: B,2 |
||||
110: -> table X (gobble 3 bits) |
||||
111: -> table Y (gobble 3 bits) |
||||
|
||||
Each entry is what the bits decode to and how many bits that is, i.e. how |
||||
many bits to gobble. Or the entry points to another table, with the number of |
||||
bits to gobble implicit in the size of the table. |
||||
|
||||
Table X is two bits long since the longest code starting with 110 is five bits |
||||
long: |
||||
|
||||
00: C,1 |
||||
01: C,1 |
||||
10: D,2 |
||||
11: E,2 |
||||
|
||||
Table Y is three bits long since the longest code starting with 111 is six |
||||
bits long: |
||||
|
||||
000: F,2 |
||||
001: F,2 |
||||
010: G,2 |
||||
011: G,2 |
||||
100: H,2 |
||||
101: H,2 |
||||
110: I,3 |
||||
111: J,3 |
||||
|
||||
So what we have here are three tables with a total of 20 entries that had to |
||||
be constructed. That's compared to 64 entries for a single table. Or |
||||
compared to 16 entries for a Huffman tree (six two entry tables and one four |
||||
entry table). Assuming that the code ideally represents the probability of |
||||
the symbols, it takes on the average 1.25 lookups per symbol. That's compared |
||||
to one lookup for the single table, or 1.66 lookups per symbol for the |
||||
Huffman tree. |
||||
|
||||
There, I think that gives you a picture of what's going on. For inflate, the |
||||
meaning of a particular symbol is often more than just a letter. It can be a |
||||
byte (a "literal"), or it can be either a length or a distance which |
||||
indicates a base value and a number of bits to fetch after the code that is |
||||
added to the base value. Or it might be the special end-of-block code. The |
||||
data structures created in inftrees.c try to encode all that information |
||||
compactly in the tables. |
