|
||||
Changes since the last public release (1.4.3):
|
||||
|
||||
version 1.2.42 [January 3, 2010]
|
||||
version 1.4.4beta01 [July 12, 2010]
|
||||
Removed extraneous new_push_process_row.c file.
|
||||
Revised the "SEE ALSO" style of libpng.3, libpngpf.3, and png.5
|
||||
Removed some newly-added TAB characters from pngpread.c.
|
||||
Fixed some indentation in pngpread.c and pngrutil.c
|
||||
Changed "extern PNG_EXPORT" to "PNG_EXPORT" in png.h (Jan Nijtmans)
|
||||
Changed "extern" to "PNG_EXTERN" in pngpriv.h (except for the 'extern "C" {')
|
||||
Put "#ifndef PNG_EXTERN, #endif" around "#define PNG_EXTERN" in pngpriv.h
|
||||
|
||||
Removed "#define PNG_NO_ERROR_NUMBERS" that was inadvertently added
|
||||
to pngconf.h in version 1.2.41.
|
||||
Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
|
||||
to put png.h and pngconf.h in $prefix/include, like the other scripts,
|
||||
instead of in $prefix/include/libpng. Also revised makefile.sco
|
||||
to put them in $prefix/include/libpng12 instead of in
|
||||
$prefix/include/libpng/libpng12.
|
||||
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from scripts/makefile.darwin
|
||||
and contrib/pngminim/*/makefile
|
||||
Relocated png_do_chop() to its original position in pngrtran.c; the
|
||||
change in version 1.2.41beta08 caused transparency to be handled wrong
|
||||
in some 16-bit datastreams (Yusaku Sugai).
|
||||
Renamed libpng-pc.in back to libpng.pc.in and revised CMakeLists.txt
|
||||
(revising changes made in 1.2.41)
|
||||
Swapped PNG_UNKNOWN_CHUNKS_SUPPORTED and PNG_HANDLE_AS_UNKNOWN_SUPPORTED
|
||||
in pngset.c to be consistent with other changes in version 1.2.38.
|
||||
Avoid deprecated references to png_ptr-io_ptr and png_ptr->error_ptr
|
||||
in pngtest.c
|
||||
version 1.4.4beta02 [July 24, 2010]
|
||||
Added -DNO_PNG_SNPRINTF to CFLAGS in scripts/makefile.dj2
|
||||
Moved the definition of png_snprintf() outside of the enclosing
|
||||
#ifdef blocks in pngconf.h
|
||||
Added a special case typedef of png_longjmp_ptr for WATCOM.
|
||||
|
||||
version 1.4.4beta03 [July 24, 2010]
|
||||
Removed reference to cbuilder5/* from Makefile.in and Makefile.am
|
||||
Eliminated the new special case typedef of png_longjmp_ptr for WATCOM
|
||||
and made a special case "#define PNGAPI" in pngconf.h instead.
|
||||
|
||||
Send comments/corrections/commendations to png-mng-implement at lists.sf.net
|
||||
version 1.4.4beta04 [July 31, 2010]

|
||||
Correct use of _WINDOWS_ in pngconf.h
|
||||
|
||||

|
||||
Don't try to use version-script with cygwin/mingw.

Revised contrib/gregbook to work under cygwin/mingw.

||||
|
||||
version 1.4.4beta07 [August 26, 2010]
|
||||
Updated prebuilt aclocal.m4 and ltmain.sh
|
||||
Add .dll.a to the list of extensions to be symlinked by Makefile.am (Yaakov)
|
||||
Updated CMakelists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for
|
||||
installing libpng in /usr/lib64 (Funda Wang).
|
||||
Revised CMakeLists.txt to put the man pages in share/man/man* not man/man*
|
||||
Revised CMakeLists.txt to make symlinks instead of copies when installing.

Known bugs in libpng version 1.2.42
|
||||
|
||||
1. December 4, 2009: The PNG_NO_ERROR_NUMBERS macro was inadvertently
|
||||
defined in libpng-1.2.41/pngconf.h, which may cause a problem with
|
||||
building a binary-compatible library.
|
||||
|
||||
STATUS: This will be fixed in libpng-1.2.42. In the meantime, simply
|
||||
delete the definition from line :
|
||||
|
||||
2. February 23, 2006: The custom makefiles don't build libpng with -lz.
|
||||
|
||||
STATUS: This is a subject of debate. The change will probably be made
|
||||
as a part of a major overhaul of the makefiles in libpng version 1.4.0.
|
||||
|
||||
3. February 24, 2006: The Makefile generated by the "configure" script
|
||||
fails to install symbolic links
|
||||
libpng12.so => libpng12.so.0.1.2.9betaN
|
||||
that are generated by the custom makefiles.
|
||||
|
||||
4. September 4, 2007: There is a report that pngtest crashes on MacOS 10.
|
||||
|
||||
STATUS: workarounds are
|
||||
1) Compile without optimization (crashes are observed with
|
||||
-arch i386 and -O2 or -O3, using gcc-4.0.1).
|
||||
2) Compile pngtest.c with PNG_DEBUG defined (the bug goes away if
|
||||
you try to look at it).
|
||||
3) Ignore the crash. The library itself seems to be OK.

Y2K compliance in libpng:
|
||||
=========================
|
||||
|
||||
January 3, 2010
|
||||
|
||||
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 1.2.42 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.

Private libpng prototypes and macro definitions were moved from

|

|
||||
Functions png_set_benign_errors(), png_benign_error(), and
|
||||
png_chunk_benign_error() were added.
|
||||
|
||||
Support for setting the maximum amount of memory that the application
|
||||
will allocate for reading chunks was added, as a security measure.
|
||||
The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
|
||||
were added to the library.
|
||||
|
||||
We implemented support for I/O states by adding png_ptr member io_state
|
||||
and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
|
||||
|
||||
We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
|
||||
input transforms.
|
||||
|
||||
Checking for and reporting of errors in the IHDR chunk is more thorough.
|
||||
|
||||
Support for global arrays was removed, to improve thread safety.
|
||||
|
||||
Some obsolete/deprecated macros and functions have been removed.
|
||||
|
||||
Typecasted NULL definitions such as
|
||||
#define png_voidp_NULL (png_voidp)NULL
|
||||
were eliminated. If you used these in your application, just use
|
||||
NULL instead.
|
||||
|
||||
The png_struct and info_struct members "trans" and "trans_values" were
|
||||
changed to "trans_alpha" and "trans_color", respectively.
|
||||
|
||||
The obsolete, unused pnggccrd.c and pngvcrd.c files and related makefiles
|
||||
were removed.
|
||||
|
||||
The PNG_1_0_X and PNG_1_2_X macros were eliminated.
|
||||
|
||||
The PNG_LEGACY_SUPPORTED macro was eliminated.
|
||||
|
||||
Many WIN32_WCE #ifdefs were removed.
|
||||
|
||||
The functions png_read_init(info_ptr), png_write_init(info_ptr),
|
||||
png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
|
||||
have been removed. They have been deprecated since libpng-0.95.
|
||||
|
||||
The png_permit_empty_plte() was removed. It has been deprecated
|
||||
since libpng-1.0.9. Use png_permit_mng_features() instead.
|
||||
|
||||
We removed the obsolete stub functions png_get_mmx_flagmask(),
|
||||
png_set_mmx_thresholds(), png_get_asm_flags(),
|
||||
png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
|
||||
png_set_asm_flags(), and png_mmx_supported()
|
||||
|
||||
We removed the obsolete png_check_sig(), png_memcpy_check(), and
|
||||
png_memset_check() functions. Instead use !png_sig_cmp(), png_memcpy(),
|
||||
and png_memset(), respectively.
|
||||
|
||||
The function png_set_gray_1_2_4_to_8() was removed. It has been
|
||||
deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
|
||||
png_set_expand_gray_1_2_4_to_8() because the former function also
|
||||
expanded palette images.
|
||||
|
||||
We changed the prototype for png_malloc() from
|
||||
png_malloc(png_structp png_ptr, png_uint_32 size)
|
||||
to
|
||||
png_malloc(png_structp png_ptr, png_alloc_size_t size)
|
||||
|
||||
This also applies to the prototype for the user replacement malloc_fn().
|
||||
|
||||
The png_calloc() function was added and is used in place of
|
||||
of "png_malloc(); png_memset();" except in the case in png_read_png()
|
||||
where the array consists of pointers; in this case a "for" loop is used
|
||||
after the png_malloc() to set the pointers to NULL, to give robust.
|
||||
behavior in case the application runs out of memory part-way through
|
||||
the process.
|
||||
|
||||
We changed the prototypes of png_get_compression_buffer_size() and
|
||||
png_set_compression_buffer_size() to work with png_size_t instead of
|
||||
png_uint_32.
|
||||
|
||||
Support for numbered error messages was removed by default, since we
|
||||
never got around to actually numbering the error messages. The function
|
||||
png_set_strip_error_numbers() was removed from the library by default.
|
||||
|
||||
The png_zalloc() and png_zfree() functions are no longer exported.
|
||||
The png_zalloc() function no longer zeroes out the memory that it
|
||||
allocates.

|
||||
Support for dithering was disabled by default in libpng-1.4.0, because
|
||||
been well tested and doesn't actually "dither". The code was not
|
||||
removed, however, and could be enabled by building libpng with
|
||||
PNG_READ_DITHER_SUPPORTED defined. In libpng-1.4.2, this support
|
||||
was reenabled, but the function was renamed png_set_quantize() to
|
||||
reflect more accurately what it actually does. At the same time,
|
||||
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros were also renamed to
|
||||
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.

|
||||
|
||||
Functions png_set_benign_errors(), png_benign_error(), and
|

png_chunk_benign_error() were added.
|
||||
|
||||
Support for setting the maximum amount of memory that the application
|
||||
will allocate for reading chunks was added, as a security measure.
|
||||
The functions png_set_chunk_cache_max() and png_get_chunk_cache_max()
|
||||
were added to the library.
|
||||
|
||||
We implemented support for I/O states by adding png_ptr member io_state
|
||||
and functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
|
||||
|
||||
We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
|
||||
input transforms.
|
||||
|
||||
Checking for and reporting of errors in the IHDR chunk is more thorough.
|
||||
|
||||
Support for global arrays was removed, to improve thread safety.
|
||||
|
||||
Some obsolete/deprecated macros and functions have been removed.
|
||||
|
||||
Typecasted NULL definitions such as
|
||||
#define png_voidp_NULL (png_voidp)NULL
|
||||
were eliminated. If you used these in your application, just use
|
||||
NULL instead.
|
||||
|
||||
The png_struct and info_struct members "trans" and "trans_values" were
|
||||
changed to "trans_alpha" and "trans_color", respectively.
|
||||
|
||||
The obsolete, unused pnggccrd.c and pngvcrd.c files and related makefiles
|
||||
were removed.
|
||||
|
||||
The PNG_1_0_X and PNG_1_2_X macros were eliminated.
|
||||
|
||||
The PNG_LEGACY_SUPPORTED macro was eliminated.
|
||||
|
||||
Many WIN32_WCE #ifdefs were removed.
|
||||

The functions png_read_init(info_ptr), png_write_init(info_ptr),

png_info_init(info_ptr), png_read_destroy(), and png_write_destroy()
|
||||
have been removed. They have been deprecated since libpng-0.95.

The png_permit_empty_plte() was removed. It has been deprecated
|

since libpng-1.0.9. Use png_permit_mng_features() instead.
|
||||
|
||||
We removed the obsolete stub functions png_get_mmx_flagmask(),
|

png_set_mmx_thresholds(), png_get_asm_flags(),
|
||||
png_get_mmx_bitdepth_threshold(), png_get_mmx_rowbytes_threshold(),
|

png_set_asm_flags(), and png_mmx_supported()
|
||||
|
||||
We removed the obsolete png_check_sig(), png_memcpy_check(), and
|
||||
png_memset_check() functions. Instead use !png_sig_cmp(), png_memcpy(),
|
||||
and png_memset(), respectively.
|
||||
|
||||
The function png_set_gray_1_2_4_to_8() was removed. It has been
|
||||
deprecated since libpng-1.0.18 and 1.2.9, when it was replaced with
|
||||
png_set_expand_gray_1_2_4_to_8() because the former function also
|
||||
expanded palette images.
|
||||
|
||||
We changed the prototype for png_malloc() from
|
||||
png_malloc(png_structp png_ptr, png_uint_32 size)
|
||||
to
|
||||
png_malloc(png_structp png_ptr, png_alloc_size_t size)
|
||||
|
||||
This also applies to the prototype for the user replacement malloc_fn().
|
||||
|
||||
The png_calloc() function was added and is used in place of
|
||||
of "png_malloc(); png_memset();" except in the case in png_read_png()
|
||||
where the array consists of pointers; in this case a "for" loop is used
|
||||
after the png_malloc() to set the pointers to NULL, to give robust.
|
||||
behavior in case the application runs out of memory part-way through
|
||||
the process.
|
||||
|
||||
We changed the prototypes of png_get_compression_buffer_size() and
|
||||
png_set_compression_buffer_size() to work with png_size_t instead of
|
||||
png_uint_32.
|
||||
|
||||
Support for numbered error messages was removed by default, since we
|
||||
never got around to actually numbering the error messages. The function
|
||||
png_set_strip_error_numbers() was removed from the library by default.
|
||||
|
||||
The png_zalloc() and png_zfree() functions are no longer exported.
|
||||
The png_zalloc() function no longer zeroes out the memory that it
|
||||
allocates.
|
||||
|
||||
Support for dithering was disabled by default in libpng-1.4.0, because
|
||||
been well tested and doesn't actually "dither". The code was not
|
||||
removed, however, and could be enabled by building libpng with
|
||||
PNG_READ_DITHER_SUPPORTED defined. In libpng-1.4.2, this support
|
||||
was reenabled, but the function was renamed png_set_quantize() to
|
||||
reflect more accurately what it actually does. At the same time,
|
||||
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros were also renamed to
|
||||
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
|

Project files to build libpng using Borland C++ Builder v5.0
|
||||
|
||||
In order to build and use libpng, please follow these steps:
|
||||
|
||||
1). Install zlib in a directory at the same level with libpng.
|
||||
|
||||
2). In a console window, go to the zlib directory and type:
|
||||
make -f win32\Makefile.bor
|
||||
After performing this step, you should have a file named
|
||||
zlib.lib in the zlib directory.
|
||||
|
||||
3). Add the following conditional define to your project:
|
||||
PNG_USE_DLL
|
||||
|
||||
4). Add libpng.lib or libpngstat.lib to the project.
|
||||
Build the project.
|
||||
|
||||
5). If the build fails, add the paths to png.h and zlib.h to
|
||||
your include path, and restart the build.
|
||||
|
||||
By default, the libpng project uses zlib as a static library. If
|
||||
you wish to use zlib as a DLL, please read the important notes from
|
||||
the zlib DLL FAQ, found inside the zlib distribution.
|
||||
|
||||
See the libpng documentation for instructions on how to use the code.
