- Ported some cosmetic changes from libpng-1.4.0beta86.
+version 1.4.0beta86 [October 9, 2009]
+ Updated the "xcode" project (Alam Arias).
Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
-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 1.4.0rc01 [October 19, 2009]
+ Trivial cosmetic 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 1.4.0beta87 [October 30, 2009]
+ Moved version 1.4.0 back into beta.
-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 1.4.0beta88 [October 30, 2009]
+ Revised libpng*.txt section about differences between 1.2.x and 1.4.0
+ because most of the new features have now been ported back to 1.2.41
-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 1.2.41beta09 [November 1, 2009]
- Removed a harmless extra png_set_invert_alpha() from pngwrite.c
+version 1.4.0beta89 [November 1, 2009]
More bugfixes and improvements to CMakeLists.txt (Philip Lowman)
- Moved CMakeLists.txt from scripts into the main libpng directory.
+ Removed a harmless extra png_set_invert_alpha() from pngwrite.c
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 1.2.41beta10 [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 1.4.0beta90 [November 2, 2009]
+ Removed all remaining WIN32_WCE #ifdefs except those involving the
+ time.h "tm" structure
-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 1.2.41beta12 [November 2, 2009]
- Free png_ptr->user_png_ver when destroying png_ptr.
-
-version 1.2.41beta13 [November 3, 2009]
+version 1.4.0beta91 [November 3, 2009]
Updated scripts/pngw32.def and projects/wince/png32ce.def
Copied projects/wince/png32ce.def to the scripts directory.
Added scripts/makefile.wce
Patched ltmain.sh for wince support.
Added PNG_CONVERT_tIME_SUPPORTED macro.
-version 1.2.41beta14 [November 8, 2009]
- versions 1.2.41beta05 through 1.2.41beta13 were abandoned.
- The 1.0.x/1.2.x series will only receive security updates from now on.
+version 1.4.0beta92 [November 4, 2009]
Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED
Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED
- Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and
- 1.2.41beta12.
- Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features
- from 1.2.41beta08.
- Retained png_calloc() from 1.2.41beta08 but as a non-exported function,
- and removed reference to png_calloc from scripts/*.def
+ Revised libpng*.txt to describe differences from 1.2.40 to 1.4.0 (instead

-Known bugs in libpng version 1.2.41beta19
-
-1. 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.
-
-2. 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.
-
-3. 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:
- =========================
-
- November 11, 2009
-
- 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 1.2.41beta19 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.

+The obsolete, unused pnggccrd.c and pngvcrd.files were removed.
+
+The PNG_1_0_X and PNG_1_2_X macros were eliminated.
+
+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
+
+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.
+
+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.
+
+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_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 png_check_sig(), png_memcpy_check(), and
+png_memset_check() functions.
+
+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)
+
+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.
+
+The png_zalloc() function no longer zeroes out the memory that it
+allocates.

-This project builds a shared library version of libpng on x86 BeOS.
-
-It defines PNG_USE_PNGGCCRD, which activates the assembly code in
-pnggccrd.c; this hasn't been extensively tested on BeOS.
-
-To install:
-
-1) build
-
- Note: As of version 1.0.10, you'll get a fair number of warnings when
- you compile pnggccrd.c. As far as I know, these are harmless,
- but it would be better if someone fixed them.
-
-2) copy and png.h, pngconf.h somewhere; /boot/home/config/include (which
- you'll have to make) is a good choice
-
-3) copy libpng.so to /boot/home/config/lib
-
-4) build your libpng.so applications (remember to include libz.a as
- well when you link)

-This project builds a static library version of libpng on x86 BeOS.
-
-It defines PNG_USE_PNGGCCRD, which activates the assembly code in
-pnggccrd.c; this hasn't been extensively tested on BeOS.
-
-To install:
-
-1) build
-
- Note: As of version 1.0.10, you'll get a fair number of warnings when
- you compile pnggccrd.c. As far as I know, these are harmless,
- but it would be better if someone fixed them.
-
-2) copy and png.h, pngconf.h somewhere; /boot/home/config/include (which
- you'll have to make) is a good choice
-
-3) copy libpng.a to /boot/home/config/lib
-
-4) build your libpng.a applications (remember to include libz.a as
- well when you link)

+It needs to *not* depend on pnggccrd.c or pngvcrd.c
+
+It needs to DEFINE PNG_CONFIGURE_LIBPNG while building
