Changes since the last public release (1.2.40):
Changes since the last public release (1.0.37):
version 1.2.41beta01 [September 25, 2009]
Moved redundant IHDR checking into new png_check_IHDR() in png.c
and report all errors found in the IHDR data.
Eliminated useless call to png_check_cHRM() from pngset.c
Expanded TAB characters in pngrtran.c
version 1.2.29beta01 [May 1, 2008]
Removed some stray *.diff and *.orig files
version 1.2.41beta02 [September 30, 2009]
Revised png_check_IHDR().
version 1.2.29beta02 [May 1, 2008]
Reverted Makefile.in, aclocal.m4, and configure to the libpng-1.2.26
versions.
version 1.2.41beta03 [October 1, 2009]
Revised png_check_IHDR() again, to check info_ptr members instead of
the contents of the returned parameters.
version 1.2.29beta03 [May 2, 2008]
Added --force to autogen libtoolize options and --force-missing to
automake options.
Changed $(ECHO) to echo in Makefile.am and Makefile.in
Updated all configure files to autoconf-2.62
#ifdef out pnggcrd.c code if using MSC_VER
version 1.2.41beta04 [October 7, 2009]
Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias).
Ported some cosmetic changes from libpng-1.4.0beta86.
Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
version 1.2.29rc01 [May 4, 2008]
No changes.
version 1.2.41beta05 [October 17, 2009]
Revised pngconf.h to make it easier to enable iTXt support. From libpng
version 1.2.9 through 1.2.40, defining PNG_iTXt_SUPPORTED did not work
as expected.
Ported some cosmetic changes from libpng-1.4.0beta87, changing
many "#if defined(x)" to "#ifdef x".
version 1.0.35 and 1.2.29 [May 8, 2008]
No changes.
version 1.2.41beta06 [October 18, 2009]
Restored PNG_USE_LOCAL_ARRAYS code in pngread.c that was inadvertently
deleted in libpng-1.2.41beta05.
Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h
as in libpng-1.4.0beta78 and later.
version 1.0.37 [May 9, 2008]
Updated Makefile.in and configure (omitted version 1.0.36).
version 1.2.41beta07 [October 21, 2009]
Ported some cosmetic changes from libpng-1.4.0rc01, changing
many "#if defined(x)" to "#ifdef x" in png.h and pngconf.h.
version 1.2.30beta01 [May 29, 2008]
Updated libpng.pc-configure.in and libpng-config.in per debian bug reports.
version 1.2.41beta08 [October 30, 2009]
Ported from libpng-1.4.0rc01: png_calloc(), png_get_io_chunk_name(),
png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(),
png_set_premultiply_alpha, and png_do_read_premultiply_alpha().
Relocated png_do_chop() ahead of building gamma tables in pngrtran.c
This avoids building 16-bit gamma tables unnecessarily.
version 1.2.30beta02 [June 25, 2008]
Restored png_flush(png_ptr) at the end of png_write_end(), that was
removed from libpng-1.0.9beta03.
version 1.2.41beta09 [November 1, 2009]
Removed a harmless extra png_set_invert_alpha() from pngwrite.c
More bugfixes and improvements to CMakeLists.txt (Philip Lowman)
Moved CMakeLists.txt from scripts into the main libpng directory.
Apply png_user_chunk_cache_max within png_decompress_chunk().
Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate.
version 1.2.30beta03 [July 6, 2008]
Merged some cosmetic whitespace changes from libpng-1.4.0beta19.
Inline call of png_get_uint_32() in png_get_uint_31(), as in 1.4.0beta19.
Added demo of decoding vpAg and sTER chunks to pngtest.c, from 1.4.0beta19.
Changed PNGMAJ from 0 to 12 in makefile.darwin, which does not like 0.
Added new private function png_read_chunk_header() from 1.4.0beta19.
Merged reading of chunk length and chunk type into a single 8-byte read.
Merged writing of chunk length and chunk type into a single 8-byte write.
version 1.2.41beta10 [November 1, 2009]
Enabled iTXt support by default. To ensure binary compatibility with
previous versions, the "lang" and "lang_key" members will be assumed
to be omitted from previous versions unless the current libpng
version was built with PNG_iTXt_SUPPORTED (which is otherwise no
longer necessary to gain iTXt support), as a signal that the user has
been building previous versions with PNG_iTXt_SUPPORTED as well.
version 1.2.30beta04 [July 10, 2008]
Merged more cosmetic whitespace changes from libpng-1.4.0beta19.
version 1.2.41beta11 [November 2, 2009]
Store user's user_png_ver in new png_ptr->user_png_ver element.
Revised iTXt support. To ensure binary compatibility with
previous versions, the "lang" and "lang_key" members will be assumed
to be omitted from versions prior to 1.2.41beta11 whenever there is a
library mismatch.
version 1.0.38rc01, 1.2.30rc01 [July 17, 2008]
No changes.
version 1.0.38rc02, 1.2.30rc02 [July 21, 2008]
Moved local array "chunkdata" from pngrutil.c to the png_struct, so
it will be freed by png_read_destroy() in case of a read error.
version 1.2.41beta12 [November 2, 2009]
Free png_ptr->user_png_ver when destroying png_ptr.

version was built with PNG_iTXt_SUPPORTED (which is otherwise no
longer necessary to gain iTXt support), as a signal that the user has
been building previous versions with PNG_iTXt_SUPPORTED as well.
version 1.2.41beta11 [November 2, 2009]
Store user's user_png_ver in new png_ptr->user_png_ver element.

Y2K compliance in libpng:
=========================
November 2, 2009
July 21, 2008
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 1.2.41beta12 are Y2K compliant. It is my belief that earlier
upward through 1.0.38rc02 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

User limits
The PNG specification allows the width and height of an image to be as
large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.
Since very few applications really need to process such large images,
we have imposed an arbitrary 1-million limit on rows and columns.
Larger images will be rejected immediately with a png_error() call. If
you wish to override this limit, you can use
png_set_user_limits(png_ptr, width_max, height_max);
to set your own limits, or use width_max = height_max = 0x7fffffffL
to allow all valid dimensions (libpng may reject some very large images
anyway because of potential buffer overflow conditions).
You should put this statement after you create the PNG structure and
before calling png_read_info(), png_read_png(), or png_process_data().
If you need to retrieve the limits that are being applied, use
width_max = png_get_user_width_max(png_ptr);
height_max = png_get_user_height_max(png_ptr);
The PNG specification sets no limit on the number of ancillary chunks
allowed in a PNG datastream. You can impose a limit on the total number
of sPLT, tEXt, iTXt, zTXt, and unknown chunks that will be stored, with
png_set_chunk_cache_max(png_ptr, user_chunk_cache_max);
where 0x7fffffffL means unlimited. You can retrieve this limit with
chunk_cache_max = png_get_chunk_cache_max(png_ptr);
This limit also applies to the number of buffers that can be allocated
by png_decompress_chunk() while decompressing iTXt, zTXt, and iCCP chunks.

accomplish this, the functions png_create_read_struct_2(),
png_create_write_struct_2(), png_set_mem_fn(), png_get_mem_ptr(),
png_malloc_default(), and png_free_default() were added.
Support for the iTXt chunk has been enabled by default as of
version 1.2.41.
Support for certain MNG features was enabled.
Support for numbered error messages was added. However, we never got
around to actually numbering the error messages. The function
png_set_strip_error_numbers() was added (Note: the prototype for this
function was inadvertently removed from png.h in PNG_NO_ASSEMBLER_CODE
builds of libpng-1.2.15. It was restored in libpng-1.2.36).
The png_malloc_warn() function was added at libpng-1.2.3. This issues
a png_warning and returns NULL instead of aborting when it fails to
acquire the requested memory allocation.
Support for setting user limits on image width and height was enabled
by default. The functions png_set_user_limits(), png_get_user_width_max(),
and png_get_user_height_max() were added at libpng-1.2.6.
The png_set_add_alpha() function was added at libpng-1.2.7.
The function png_set_expand_gray_1_2_4_to_8() was added at libpng-1.2.9.
Unlike png_set_gray_1_2_4_to_8(), the new function does not expand the
tRNS chunk to alpha. The png_set_gray_1_2_4_to_8() function is
deprecated.

assembler code features (especially Intel MMX code support) were

png_get_mmx_bitdepth_threshold()
png_get_mmx_rowbytes_threshold()

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. Added png_ptr member io_state, and
functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
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.
We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
input transforms.
We added the png_set_premultiply_alpha and
png_do_read_premultiply_alpha() functions.
The call to png_do_chop() in pngrtran.c, which reduces 16-bit input
files to 8-bit bit depth, was relocated ahead of the building
of gamma tables. This allows us to build 8-bit tables instead
of 16-bit tables, when only 8-bit tables are needed. This avoids
wasting some computing resources when the application has called
the png_set_strip_16() function and encounters a 16-bit PNG file.
Checking for and reporting of errors in the IHDR chunk is more thorough.
IX. (Omitted)
X. Detecting libpng
The png_get_io_ptr() function has been present since libpng-0.88, has never
changed, and is unaffected by conditional compilation macros. It is the
best choice for use in configure scripts for detecting the presence of any
libpng version since 0.88. In an autoconf "configure.in" you could use
AC_CHECK_LIB(png, png_get_io_ptr, ...
XI. Source code repository
Since about February 2009, version 1.2.34, libpng has been under "git" source
control. The git repository was built from old libpng-x.y.z.tar.gz files
going back to version 0.70. You can access the git repository (read only)
at
git://libpng.git.sourceforge.net/gitroot/libpng
or you can browse it via "gitweb" at
http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
Patches can be sent to glennrp at users.sourceforge.net or to
png-mng-implement at lists.sourceforge.net or you can upload them to
the libpng bug tracker at
http://libpng.sourceforge.net
XII. Coding style
Our coding style is similar to the "Allman" style, with curly
braces on separate lines:
if (condition)
{
action;
}
else if (another condition)
{
another action;
}
The braces can be omitted from simple one-line actions:
if (condition)
return (0);
We use 3-space indentation, except for continued statements which
are usually indented the same as the first line of the statement
plus four more spaces.
For macro definitions we use 2-space indentation, always leaving the "#"
in the first column.
#ifndef PNG_NO_FEATURE
# ifndef PNG_FEATURE_SUPPORTED
# define PNG_FEATURE_SUPPORTED
# endif
#endif
Comments appear with the leading "/*" at the same indentation as
the statement that follows the comment:
/* Single-line comment */
statement;
/* Multiple-line
* comment
*/
statement;
Very short comments can be placed at the end of the statement
to which they pertain:
statement; /* comment */
We don't use C++ style ("//") comments. We have, however,
used them in the past in some now-abandoned MMX assembler
code.
Functions and their curly braces are not indented, and
exported functions are marked with PNGAPI:
/* This is a public function that is visible to
* application programers. It does thus-and-so.
*/
void PNGAPI
png_exported_function(png_ptr, png_info, foo)
{
body;
}
The prototypes for all exported functions appear in png.h,
above the comment that says
/* Maintainer: Put new public prototypes here ... */
We mark all non-exported functions with "/* PRIVATE */"":
void /* PRIVATE */
png_non_exported_function(png_ptr, png_info, foo)
{
body;
}
The prototypes for non-exported functions (except for those in
pngtest) appear in
the PNG_INTERNAL section of png.h
above the comment that says
/* Maintainer: Put new private prototypes here ^ and in libpngpf.3 */
The names of all exported functions and variables begin
with "png_", and all publicly visible C preprocessor
macros begin with "PNG_".
We put a space after each comma and after each semicolon
in "for" statments, and we put spaces before and after each
C binary operator and after "for" or "while". We don't
put a space between a typecast and the expression being
cast, nor do we put one between a function name and the
left parenthesis that follows it:
for (i = 2; i > 0; --i)
y[i] = a(x) + (int)b;
We prefer #ifdef and #ifndef to #if defined() and if !defined()
when there is only one macro being tested.
We do not use the TAB character for indentation in the C sources.
Other rules can be inferred by inspecting the libpng
source.
XIII. Y2K Compliance in libpng
November 2, 2009
July 21, 2008
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 1.2.41beta12 are Y2K compliant. It is my belief that earlier
upward through 1.0.38rc02 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.

.SS User limits
The PNG specification allows the width and height of an image to be as
large as 2^31-1 (0x7fffffff), or about 2.147 billion rows and columns.
Since very few applications really need to process such large images,
we have imposed an arbitrary 1-million limit on rows and columns.
Larger images will be rejected immediately with a png_error() call. If
you wish to override this limit, you can use
png_set_user_limits(png_ptr, width_max, height_max);
to set your own limits, or use width_max = height_max = 0x7fffffffL
to allow all valid dimensions (libpng may reject some very large images
anyway because of potential buffer overflow conditions).
You should put this statement after you create the PNG structure and
before calling png_read_info(), png_read_png(), or png_process_data().
If you need to retrieve the limits that are being applied, use
width_max = png_get_user_width_max(png_ptr);
height_max = png_get_user_height_max(png_ptr);
The PNG specification sets no limit on the number of ancillary chunks
allowed in a PNG datastream. You can impose a limit on the total number
of sPLT, tEXt, iTXt, zTXt, and unknown chunks that will be stored, with
png_set_chunk_cache_max(png_ptr, user_chunk_cache_max);
where 0x7fffffffL means unlimited. You can retrieve this limit with
chunk_cache_max = png_get_chunk_cache_max(png_ptr);
This limit also applies to the number of buffers that can be allocated
by png_decompress_chunk() while decompressing iTXt, zTXt, and iCCP chunks.

selection of assembler code features:
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()
We replaced all of these functions with simple stubs in libpng-1.2.20,
when the Intel assembler code was removed due to a licensing issue.
These macros are deprecated:
PNG_READ_TRANSFORMS_NOT_SUPPORTED
PNG_PROGRESSIVE_READ_NOT_SUPPORTED
PNG_NO_SEQUENTIAL_READ_SUPPORTED
PNG_WRITE_TRANSFORMS_NOT_SUPPORTED
PNG_READ_ANCILLARY_CHUNKS_NOT_SUPPORTED
PNG_WRITE_ANCILLARY_CHUNKS_NOT_SUPPORTED
They have been replaced, respectively, by:
PNG_NO_READ_TRANSFORMS
PNG_NO_PROGRESSIVE_READ
PNG_NO_SEQUENTIAL_READ
PNG_NO_WRITE_TRANSFORMS
PNG_NO_READ_ANCILLARY_CHUNKS
PNG_NO_WRITE_ANCILLARY_CHUNKS
PNG_MAX_UINT was replaced with PNG_UINT_31_MAX. It has been
deprecated since libpng-1.0.16 and libpng-1.2.6.
The function
png_check_sig(sig, num)
was replaced with
!png_sig_cmp(sig, 0, num)
It has been deprecated since libpng-0.90.
The function
png_set_gray_1_2_4_to_8()
which also expands tRNS to alpha was replaced with
png_set_expand_gray_1_2_4_to_8()
which does not. It has been deprecated since libpng-1.0.18 and 1.2.9.
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. Added png_ptr member io_state, and
functions png_get_io_chunk_name() and png_get_io_state() in pngget.c
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.
We added PNG_TRANSFORM_GRAY_TO_RGB to the available high-level
input transforms.
We added the png_set_premultiply_alpha and
png_do_read_premultiply_alpha() functions.
The call to png_do_chop() in pngrtran.c, which reduces 16-bit input
files to 8-bit bit depth, was relocated ahead of the building
of gamma tables. This allows us to build 8-bit tables instead
of 16-bit tables, when only 8-bit tables are needed. This avoids
wasting some computing resources when the application has called
the png_set_strip_16() function and encounters a 16-bit PNG file.
Checking for and reporting of errors in the IHDR chunk is more thorough.
.SH IX. (Omitted)
.SH X. Detecting libpng
The png_get_io_ptr() function has been present since libpng-0.88, has never
changed, and is unaffected by conditional compilation macros. It is the
best choice for use in configure scripts for detecting the presence of any
libpng version since 0.88. In an autoconf "configure.in" you could use
AC_CHECK_LIB(png, png_get_io_ptr, ...
.SH XI. Source code repository
Since about February 2009, version 1.2.34, libpng has been under "git" source
control. The git repository was built from old libpng-x.y.z.tar.gz files
going back to version 0.70. You can access the git repository (read only)
at
git://libpng.git.sourceforge.net/gitroot/libpng
or you can browse it via "gitweb" at
http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
Patches can be sent to glennrp at users.sourceforge.net or to
png-mng-implement at lists.sourceforge.net or you can upload them to
the libpng bug tracker at
http://libpng.sourceforge.net
.SH XII. Coding style
Our coding style is similar to the "Allman" style, with curly
braces on separate lines:
if (condition)
{
action;
}
else if (another condition)
{
another action;
}
The braces can be omitted from simple one-line actions:
if (condition)
return (0);
We use 3-space indentation, except for continued statements which
are usually indented the same as the first line of the statement
plus four more spaces.
For macro definitions we use 2-space indentation, always leaving the "#"
in the first column.
#ifndef PNG_NO_FEATURE
# ifndef PNG_FEATURE_SUPPORTED
# define PNG_FEATURE_SUPPORTED
# endif
#endif
Comments appear with the leading "/*" at the same indentation as
the statement that follows the comment:
/* Single-line comment */
statement;
/* Multiple-line
* comment
*/
statement;
Very short comments can be placed at the end of the statement
to which they pertain:
statement; /* comment */
We don't use C++ style ("//") comments. We have, however,
used them in the past in some now-abandoned MMX assembler
code.
Functions and their curly braces are not indented, and
exported functions are marked with PNGAPI:
/* This is a public function that is visible to
* application programers. It does thus-and-so.
*/
void PNGAPI
png_exported_function(png_ptr, png_info, foo)
{
body;
}
The prototypes for all exported functions appear in png.h,
above the comment that says
/* Maintainer: Put new public prototypes here ... */
We mark all non-exported functions with "/* PRIVATE */"":
void /* PRIVATE */
png_non_exported_function(png_ptr, png_info, foo)
{
body;
}
The prototypes for non-exported functions (except for those in
pngtest) appear in
the PNG_INTERNAL section of png.h
above the comment that says
/* Maintainer: Put new private prototypes here ^ and in libpngpf.3 */
The names of all exported functions and variables begin
with "png_", and all publicly visible C preprocessor
macros begin with "PNG_".
We put a space after each comma and after each semicolon
in "for" statments, and we put spaces before and after each
C binary operator and after "for" or "while". We don't
put a space between a typecast and the expression being
cast, nor do we put one between a function name and the
left parenthesis that follows it:
for (i = 2; i > 0; --i)
y[i] = a(x) + (int)b;
We prefer #ifdef and #ifndef to #if defined() and if !defined()
when there is only one macro being tested.
We do not use the TAB character for indentation in the C sources.
Other rules can be inferred by inspecting the libpng
source.
.SH XIII. Y2K Compliance in libpng
November 2, 2009
July 21, 2008
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 1.2.41beta12 are Y2K compliant. It is my belief that earlier
upward through 1.0.38rc02 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
