zlib 1.0.4 is a general purpose data compression library. All the code
|
||||
is reentrant (thread safe). The data format used by the zlib library
|
||||
is described by RFCs (Request for Comments) 1950 to 1952 in the files
|
||||
ftp://ds.internic.net/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
|
||||
ZLIB DATA COMPRESSION LIBRARY
|
||||
|
||||
All functions of the compression library are documented in the file
|
||||
zlib.h. 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 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.
|
||||
|
||||
- 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)
|
||||
- port to RISCOS (no fdopen, no multiple dots, no unlink, no fileno)
|
||||
PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html before asking
|
||||
for help.

Notes for some targets:
|
||||
|
||||
- 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 Windows DLL versions, please see win32/DLL_FAQ.txt
|
||||
|
||||
- For 64-bit Iris, deflate.c must be compiled without any optimization.
|
||||
With -O, one libpng test fails. The test works in 32 bit mode (with
|
||||
the -32 compiler flag). The compiler bug has been reported to SGI.
|
||||
- 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.
|
||||
- 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.
|
||||
|
||||
- zlib doesn't work on HP-UX 9.05 with one cc compiler (the one not
|
||||
accepting the -O option). It works with the other cc compiler.
|
||||
- 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.
|
||||
|
||||
- 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
|
||||
For help on building a zlib DLL, contact Alessandro Iacopetti
|
||||
<iaco@email.alessandria.alpcom.it> http://lisa.unial.it/iaco ,
|
||||
or contact Brad Clarke <bclarke@cyberus.ca>.
|
||||
- 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
|
||||
- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
|
||||
|
||||
- For PalmOs, see http://palmzlib.sourceforge.net/
|
||||
|
||||
- When building a shared, i.e. dynamic library on Mac OS X, the library must be
|
||||
installed before testing (do "make install" before "make test"), since the
|
||||
library location is specified in the library.

Notes:
|

|

- The maximum input bits used by a length/distance pair is 15 bits for the
|
||||
length code, 5 bits for the length extra, 15 bits for the distance code,
|
||||
and 13 bits for the distance extra. This totals 48 bits, or six bytes.
|
||||
Therefore if strm->avail_in >= 6, then there is enough input to avoid
|
||||
checking for available input while decoding.
|
||||
|
||||
- The maximum bytes that a single length/distance pair can output is 258
|
||||
bytes, which is the maximum length that can be coded. inflate_fast()
|
||||
requires strm->avail_out >= 258 for each loop to avoid checking for
|
||||
output space.

/*
|
||||
Huffman code decoding is performed using a multi-level table lookup.
|
||||
The fastest way to decode is to simply build a lookup table whose
|
||||
size is determined by the longest code. However, the time it takes
|
||||
to build this table can also be a factor if the data being decoded
|
||||
is not very long. The most common codes are necessarily the
|
||||
shortest codes, so those codes dominate the decoding time, and hence
|
||||
the speed. The idea is you can have a shorter table that decodes the
|
||||
shorter, more probable codes, and then point to subsidiary tables for
|
||||
the longer codes. The time it costs to decode the longer codes is
|
||||
then traded against the time it takes to make longer tables.
|
||||
|
||||
This results of this trade are in the variables lbits and dbits
|
||||
below. lbits is the number of bits the first level table for literal/
|
||||
length codes can decode in one step, and dbits is the same thing for
|
||||
the distance codes. Subsequent tables are also less than or equal to
|
||||
those sizes. These values may be adjusted either when all of the
|
||||
codes are shorter than that, in which case the longest code length in
|
||||
bits is used, or when the shortest code is *longer* than the requested
|
||||
table size, in which case the length of the shortest code in bits is
|
||||
used.
|
||||
|
||||
There are two different values for the two tables, since they code a
|
||||
different number of possibilities each. The literal/length table
|
||||
codes 286 possible values, or in a flat code, a little over eight
|
||||
bits. The distance table codes 30 possible values, or a little less
|
||||
than five bits, flat. The optimum values for speed end up being
|
||||
about one bit more than those, so lbits is 8+1 and dbits is 5+1.
|
||||
The optimum values may differ though from machine to machine, and
|
||||
possibly even between compilers. Your mileage may vary.
|
||||
Build a set of tables to decode the provided canonical Huffman code.
|
||||
The code lengths are lens[0..codes-1]. The result starts at *table,
|
||||
whose indices are 0..2^bits-1. work is a writable array of at least
|
||||
lens shorts, which is used as a work area. type is the type of code
|
||||
to be generated, CODES, LENS, or DISTS. On return, zero is success,
|
||||
-1 is an invalid code, and +1 means that ENOUGH isn't enough. table
|
||||
on return points to the next available entry's address. bits is the
|
||||
requested root table index bits, and on return it is the actual root
|
||||
table index bits. It will differ if the request is greater than the
|
||||
longest code or if it is less than the shortest code.

Process a set of code lengths to create a canonical Huffman code. The
|
||||
code lengths are lens[0..codes-1]. Each length corresponds to the
|
||||
symbols 0..codes-1. The Huffman code is generated by first sorting the
|
||||
symbols by length from short to long, and retaining the symbol order
|
||||
for codes with equal lengths. Then the code starts with all zero bits
|
||||
for the first code of the shortest length, and the codes are integer
|
||||
increments for the same length, and zeros are appended as the length
|
||||
increases. For the deflate format, these bits are stored backwards
|
||||
from their more natural integer increment ordering, and so when the
|
||||
decoding tables are built in the large loop below, the integer codes
|
||||
are incremented backwards.
|
||||
|
||||
This routine assumes, but does not check, that all of the entries in
|
||||
lens[] are in the range 0..MAXBITS. The caller must assure this.
|
||||
1..MAXBITS is interpreted as that code length. zero means that that
|
||||
symbol does not occur in this code.

|

The codes are sorted by computing a count of codes for each length,
|
||||
creating from that a table of starting indices for each length in the
|
||||
sorted table, and then entering the symbols in order in the sorted
|
||||
table. The sorted table is work[], with that space being provided by
|
||||
the caller.
|
||||
|
||||
The length counts are used for other purposes as well, i.e. finding
|
||||
the minimum and maximum length codes, determining if there are any
|
||||
codes at all, checking for a valid set of lengths, and looking ahead
|
||||
at length counts to determine sub-table sizes when building the

decoding tables.

bits off of the bottom. For codes where len is less than drop + curr,

root is the number of index bits for the root table. When len exceeds

being filled, and drop is root when sub-tables are being filled.

When a new sub-table is needed, it is necessary to look ahead in the

code lengths to determine what size sub-table is needed. The length

counts are used for this, and so count[] is decremented as codes are

entered in the tables.

the worst case distance code, MAXD. This should never happen, but the
