|
|
|
|
Version 0.82 [September, 1995]
|
|
[unspecified changes]
|
|

|
Version 0.86 [January, 1996]

improved documentation
|
|
|
|
Version 0.87 [January, 1996]
|
|
fixed medium model bugs
|
|
fixed other bugs introduced in 0.85 and 0.86
|
|
added some minor documentation
|
|
|
|
Version 0.88 [January, 1996]
|
|
fixed progressive bugs
|
|
replaced tabs with spaces
|
|
cleaned up documentation
|
|
added callbacks for read/write and warning/error functions
|
|
|
|
Version 0.89 [July, 1996]
|
|
Added new initialization API to make libpng work better with shared libs
|
|
we now have png_create_read_struct(), png_create_write_struct(),
|
|
png_create_info_struct(), png_destroy_read_struct(), and
|
|
png_destroy_write_struct() instead of the separate calls to
|
|
malloc and png_read_init(), png_info_init(), and png_write_init()
|
|
Changed warning/error callback functions to fix bug - this means you
|
|
should use the new initialization API if you were using the old
|
|
png_set_message_fn() calls, and that the old API no longer exists
|
|
so that people are aware that they need to change their code
|
|
Changed filter selection API to allow selection of multiple filters
|
|
since it didn't work in previous versions of libpng anyways
|
|
Optimized filter selection code
|
|
Fixed png_set_background() to allow using an arbitrary RGB color for
|
|
paletted images
|
|
Fixed gamma and background correction for paletted images, so
|
|
png_correct_palette is not needed unless you are correcting an
|
|
external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
|
|
in pngconf.h) - if nobody uses this, it may disappear in the future.
|
|
Fixed bug with Borland 64K memory allocation (Alexander Lehmann)
|
|
Fixed bug in interlace handling (Smarasderagd, I think)
|
|
Added more error checking for writing and image to reduce invalid files
|
|
Separated read and write functions so that they won't both be linked
|
|
into a binary when only reading or writing functionality is used
|
|
New pngtest image also has interlacing and zTXt
|
|
Updated documentation to reflect new API
|
|
|
|
Version 0.90 [January, 1997]
|
|
Made CRC errors/warnings on critical and ancillary chunks configurable
|
|
libpng will use the zlib CRC routines by (compile-time) default
|
|
Changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
|
|
Added external C++ wrapper statements to png.h (Gilles Dauphin)
|
|
Allow PNG file to be read when some or all of file signature has already
|
|
been read from the beginning of the stream. ****This affects the size
|
|
of info_struct and invalidates all programs that use a shared libpng****
|
|
Fixed png_filler() declarations
|
|
Fixed? background color conversions
|
|
Fixed order of error function pointers to match documentation
|
|
Current chunk name is now available in png_struct to reduce the number
|
|
of nearly identical error messages (will simplify multi-lingual
|
|
support when available)
|
|
Try to get ready for unknown-chunk callback functions:
|
|
- previously read critical chunks are flagged, so the chunk handling
|
|
routines can determine if the chunk is in the right place
|
|
- all chunk handling routines have the same prototypes, so we will
|
|
be able to handle all chunks via a callback mechanism
|
|
Try to fix Linux "setjmp" buffer size problems
|
|
Removed png_large_malloc, png_large_free, and png_realloc functions.
|
|
|
|
Version 0.95 [March, 1997]
|
|
Fixed bug in pngwutil.c allocating "up_row" twice and "avg_row" never
|
|
Fixed bug in PNG file signature compares when start != 0
|
|
Changed parameter type of png_set_filler(...filler...) from png_byte
|
|
to png_uint_32
|
|
Added test for MACOS to ensure that both math.h and fp.h are not #included
|
|
Added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
|
|
Added "packswap" transformation, which changes the endianness of
|
|
packed-pixel bytes (Kevin Bracey)
|
|
Added "strip_alpha" transformation, which removes the alpha channel of
|
|
input images without using it (not necessarily a good idea)
|
|
Added "swap_alpha" transformation, which puts the alpha channel in front
|
|
of the color bytes instead of after
|
|
Removed all implicit variable tests which assume NULL == 0 (I think)
|
|
Changed several variables to "png_size_t" to show 16/32-bit limitations
|
|
Added new pCAL chunk read/write support
|
|
Added experimental filter selection weighting (Greg Roelofs)
|
|
Removed old png_set_rgbx() and png_set_xrgb() functions that have been
|
|
obsolete for about 2 years now (use png_set_filler() instead)
|
|
Added macros to read 16- and 32-bit ints directly from buffer, to be
|
|
used only on those systems that support it (namely PowerPC and 680x0)
|
|
With some testing, this may become the default for MACOS/PPC systems.
|
|
Only calculate CRC on data if we are going to use it
|
|
Added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
|
|
Added macros for simple libpng debugging output selectable at compile time
|
|
Removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
|
|
More description of info_struct in libpng.txt and png.h
|
|
More instructions in example.c
|
|
More chunk types tested in pngtest.c
|
|
Renamed pngrcb.c to pngset.c, and all png_read_<chunk> functions to be
|
|
png_set_<chunk>. We now have corresponding png_get_<chunk>
|
|
functions in pngget.c to get information in info_ptr. This isolates
|
|
the application from the internal organization of png_info_struct
|
|
(good for shared library implementations).
|
|
|
|

|
|
Minor corrections in libpng.txt
|
|
Added simple sRGB support (Glenn R-P)
|
|

|
|
of having to edit pngconf.h (Glenn R-P)
|
|
Fixed memory leak in pngwrite.c (free info_ptr->text) (Glenn R-P)
|
|
Added more conditions for png_do_background, to avoid changing
|
|
black pixels to background when a background is supplied and
|
|
no pixels are transparent
|

|
|
Tested NODIV support and made it default behaviour (Greg Roelofs)

|
|
Cosmetic change "display_gamma" to "screen_gamma" in pngrtran.c
|
|
Changed recommendation about file_gamma for PC images to .51 from .45,
|
|
in example.c and libpng.txt, added comments to distinguish between
|
|
screen_gamma, viewing_gamma, and display_gamma.
|
|
Changed all references to RFC1152 to read RFC1123 and changed the
|
|
PNG_TIME_RFC1152_SUPPORTED macro to PNG_TIME_RFC1123_SUPPORTED

|
|
|
|
Version 0.99c [February 7, 1998]
|
|
More type casting. Removed erroneous overflow test in pngmem.c.
|
|
Added png_buffered_memcpy() and png_buffered_memset(), apply them to rowbytes.

|
|
Corrected png_get_tRNS() again.
|
|
Add parentheses for easier reading of pngget.c, fixed "||" should be "&&".

|
|
too large when writing an image with bit_depth < 8 (Bob Dellaca).
|
|
Corrected some bugs in the experimental weighted filtering heuristics.
|
|
Moved a misplaced pngrutil code block that truncates tRNS if it has more

|
|
More work on the Paeth-filtering, achieving imperceptible speedup
|
|
(A Kleinert).
|

More work on loop optimization which may help when compiled with C++
|
|
compilers.

|
|
to remove unwanted capabilities via the compile line
|
|
Made some corrections to grammar (which, it's) in documentation (Greg).
|
|
Corrected example.c, use of row_pointers in png_write_image().
|
|
|
|
Version 1.0.1d [May 24, 1998]
|
|
Corrected several statements that used side effects illegally in pngrutil.c
|
|
and pngtrans.c, that were introduced in version 1.0.1b
|
|
Revised png_read_rows() to avoid repeated if-testing for NULL (A Kleinert)
|
|
More corrections to example.c, use of row_pointers in png_write_image()

|
Added pngdll.mak and pngdef.pas to scripts directory, contributed by
|
|
Bob Dellaca, to make a png32bd.dll with Borland C++ 4.5

added warnings when people try to set png_read_fn and png_write_fn in
|
|
the same structure.
|
|
Added a test such that png_do_gamma will be done when num_trans==0

|
|
error that was introduced in libpng-0.90 that can cause gamma processing
|
|
to be skipped.

PNGTEST_DEBUG_MEM feature.
|
|
Added makefile.w32, for Microsoft C++ 4.0 and later (Tim Wegner).
|
|
|

|
|
Added function png_set_user_transform_info() to store user_transform_ptr,

|
|
png_get_user_transform_ptr() to retrieve the pointer (Chris Nokleberg)
|
|
Added function png_set_empty_plte_permitted() to make libpng useable
|
|
in MNG applications.
|
|
Corrected the typedef for png_free_ptr in png.h (Jesse Jones).
|
|
Correct gamma with srgb is 45455 instead of 45000 in pngrutil.c, to be

|
|
Relocated start of 'extern "C"' block in png.h so it doesn't include pngconf.h
|
|
Revised calculation of num_blocks in pngmem.c to avoid a potentially

Further optimization and bugfix of pngvcrd.c
|
|
Revised pngset.c so that it does not allocate or free memory in the user's
|
|
text_ptr structure. Instead, it makes its own copy.
|
|
Created separate write_end_info_struct in pngtest.c for a more severe test.
|
|
Added code in pngwrite.c to free info_ptr->text[i].key to stop a memory leak.

|
|
|
|
Version 1.0.5c [November 26, 1999]
|
|
Moved png_get_header_version from png.h to png.c, to accommodate ansi2knr.
|
|
Removed all global arrays (according to PNG_NO_GLOBAL_ARRAYS macro), to
|
|
accommodate making DLL's: Moved usr_png_ver from global variable to function
|
|
png_get_header_ver() in png.c. Moved png_sig to png_sig_bytes in png.c and
|
|
eliminated use of png_sig in pngwutil.c. Moved the various png_CHNK arrays
|
|
into pngtypes.h. Eliminated use of global png_pass arrays. Declared the
|
|
png_CHNK and png_pass arrays to be "const". Made the global arrays

|
available to applications (although none are used in libpng itself) when
|
|
PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined.

|
|
Eliminated pngtypes.h; use macros instead to declare PNG_CHNK arrays.
|

|
|
PNG_USE_GLOBAL_ARRAYS is defined.
|
|
Added PNG_EXPORT_VAR macro to accommodate making DLL's.
|
|
|
|
Version 1.0.5e [November 30, 1999]
|
|
Added iCCP, iTXt, and sPLT support; added "lang" member to the png_text
|
|
structure; refactored the inflate/deflate support to make adding new chunks
|
|
with trailing compressed parts easier in the future, and added new functions
|
|
png_free_iCCP, png_free_pCAL, png_free_sPLT, png_free_text, png_get_iCCP,
|
|
png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond).
|
|
NOTE: Applications that write text chunks MUST define png_text->lang
|
|
before calling png_set_text(). It must be set to NULL if you want to
|
|
write tEXt or zTXt chunks. If you want your application to be able to
|
|
run with older versions of libpng, use
|
|
|
|
#ifdef PNG_iTXt_SUPPORTED

|
png_text[i].lang = NULL;

|
|
offsets (Eric S. Raymond).

|
|
PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED
|
|
macros, leaving the separate macros also available.
|
|
Removed comments on #endifs at the end of many short, non-nested #if-blocks.
|
|
|
|
Version 1.0.5f [December 6, 1999]

|
|
the ucb "ld" is in the path ahead of the ccs "ld".
|
|
Removed "- [date]" from the "synopsis" line in libpng.3 and libpngpf.3.
|
|
Added sCAL chunk support (Eric S. Raymond).
|
|
|
|
Version 1.0.5g [December 7, 1999]
|
|
Fixed "png_free_spallettes" typo in png.h
|
|
Added code to handle new chunks in pngpread.c
|
|

|
|
Added code in pngwrite.c to work around a newly discovered zlib bug.
|
|
|
|
Version 1.0.5h [December 10, 1999]
|
|
NOTE: regarding the note for version 1.0.5e, the following must also
|
|
be included in your code:

|
Option to eliminate all floating point support was added. Some new
|
|
fixed-point functions such as png_set_gAMA_fixed() were added.

|
|
unknown chunks in pngwrite.c
|
|
Changed "num" to "i" in png_free_spalettes() and png_free_unknowns() to
|
|
prevent recursion.
|
|
Added png_free_hIST() function.
|
|
Various patches to fix bugs in the sCAL and integer cHRM processing,
|
|
and to add some convenience macros for use with sCAL.
|
|
|
|
Version 1.0.5j [December 21, 1999]
|
|
Changed "unit" parameter of png_write_sCAL from png_byte to int, to work
|
|
around buggy compilers.
|
|
Added new type "png_fixed_point" for integers that hold float*100000 values
|
|
Restored backward compatibility of tEXt/zTXt chunk processing:
|
|
Restored the first four members of png_text to the same order as v.1.0.5d.
|
|
Added members "lang_key" and "itxt_length" to png_text struct. Set
|
|
text_length=0 when "text" contains iTXt data. Use the "compression"
|
|
member to distinguish among tEXt/zTXt/iTXt types. Added
|
|
PNG_ITXT_COMPRESSION_NONE (1) and PNG_ITXT_COMPRESSION_zTXt(2) macros.
|
|
The "Note" above, about backward incompatibility of libpng-1.0.5e, no
|
|
longer applies.
|
|
Fixed png_read|write_iTXt() to read|write parameters in the right order,

|
|
Added pnggccrd.c, version of pngvcrd.c Intel assembler for gcc (Greg Roelofs)
|

Added many parentheses, e.g., "if (a && b & c)" becomes "if (a && (b & c))"
|
|
Added png_handle_as_unknown() function (Glenn)
|
|

Fixed a libpng-1.0.5h bug in pngrutil.c that was issuing erroneous warnings
|
|
about ignoring incorrect gAMA with sRGB (gAMA was in fact not ignored)
|
|
Added png_free_tRNS(); png_set_tRNS() now malloc's its own trans array (ESR).

|
|
|
Version 1.0.5m [January 7, 2000]
|
|
Added high-level functions png_read_png(), png_write_png(), png_free_pixels().
|
|
|
|
Version 1.0.5n [January 9, 2000]
|
|
Added png_free_PLTE() function, and modified png_set_PLTE() to malloc its
|
|
own memory for info_ptr->palette. This makes it safe for the calling
|
|
application to free its copy of the palette any time after it calls
|
|
png_set_PLTE().
|
|
|
|
Version 1.0.5o [January 20, 2000]
|

|
|
Revised some of the DLL-export macros in pngconf.h (Greg Roelofs)

|
|
hasn't already been allocated.
|
|
|
|
Version 1.0.5t [March 4, 2000]

|
|
Added a check for info_ptr->free_me&PNG_FREE_TEXT when freeing text in png.c

|
|
Added png_data_freer() function.
|
|
In the code that checks for over-length tRNS chunks, added check of
|

|
|
Minor revisions of libpng.txt/libpng.3.
|
|
Check for existing data and free it if the free_me flag is set, in png_set_*()
|
|
and png_handle_*().
|
|
Only define PNG_WEIGHTED_FILTERS_SUPPORTED when PNG_FLOATING_POINT_SUPPORTED
|
|
is defined.
|
|
Changed several instances of PNG_NO_CONSOLE_ID to PNG_NO_STDIO in pngrutil.c
|

|
|
|
|
Version 1.0.6f [April 14, 2000]
|
|
Revised png_set_iCCP() and png_set_rows() to avoid prematurely freeing data.
|
|
Add checks in png_set_text() for NULL members of the input text structure.
|
|
Revised libpng.txt/libpng.3.

|
|
Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined.
|
|
Relocated paragraph about png_set_background() in libpng.3/libpng.txt
|
|
and other revisions (Matthias Benckmann)
|
|
Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and
|
|
png_ptr members to restore binary compatibility with libpng-1.0.5
|
|
(breaks compatibility with libpng-1.0.6).
|
|
|
|
Version 1.0.6h [April 24, 2000]
|
|
Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
|
|
libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)
|
|
This is a temporary change for test purposes.
|
|
|
|
Version 1.0.6i [May 2, 2000]
|
|
Rearranged some members at the end of png_info and png_struct, to put
|
|
unknown_chunks_num and free_me within the original size of the png_structs
|
|
and free_me, png_read_user_fn, and png_free_fn within the original png_info,
|
|
because some old applications allocate the structs directly instead of
|
|
using png_create_*().
|
|
Added documentation of user memory functions in libpng.txt/libpng.3
|
|
Modified png_read_png so that it will use user_allocated row_pointers
|
|
if present, unless free_me directs that it be freed, and added description
|
|
of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3.
|
|
Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version
|
|
1.00) members of png_struct and png_info, to regain binary compatibility
|
|
when you define this macro. Capabilities lost in this event
|
|
are user transforms (new in version 1.0.0),the user transform pointer
|
|
(new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
|
|
the high-level interface, and unknown chunks support (all new in 1.0.6).
|
|
This was necessary because of old applications that allocate the structs
|
|
directly as authors were instructed to do in libpng-0.88 and earlier,
|
|
instead of using png_create_*().
|
|
Added modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
|
|
can be used to detect codes that directly allocate the structs, and
|
|
code to check these modes in png_read_init() and png_write_init() and
|
|
generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
|
|
was not defined.
|
|
Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
|
|
|
|
Version 1.0.6j [May 3, 2000]
|
|
Overloaded png_read_init() and png_write_init() with macros that convert
|
|
calls to png_read_init_2() or png_write_init_2() that check the version
|
|
and structure sizes.
|
|
|
|
Version 1.0.7beta11 [May 7, 2000]
|
|
Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes
|
|
which are no longer used.
|
|
Eliminated the three new members of png_text when PNG_LEGACY_SUPPORTED is
|
|
defined or when neither PNG_READ_iTXt_SUPPORTED nor PNG_WRITE_iTXT_SUPPORTED
|
|
is defined.
|
|
Made PNG_NO_READ|WRITE_iTXt the default setting, to avoid memory
|
|
overrun when old applications fill the info_ptr->text structure directly.
|
|
Added PNGAPI macro, and added it to the definitions of all exported functions.
|
|
Relocated version macro definitions ahead of the includes of zlib.h and
|
|
pngconf.h in png.h.
|
|
|
|
Version 1.0.7beta12 [May 12, 2000]
|
|
Revised pngset.c to avoid a problem with expanding the png_debug macro.
|
|
Deleted some extraneous defines from pngconf.h
|
|
Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined.
|
|
Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined.
|
|
Added png_access_version_number() function.
|
|
Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().
|
|
Expanded libpng.3/libpng.txt information about png_data_freer().
|
|
|
|
Version 1.0.7beta14 [May 17, 2000] (beta13 was not published)
|
|
Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
|
|
warnings instead of errors, as pngrutil.c does.
|
|
Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
|
|
will actually write IDATs.
|
|
Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
|
|
Make png_free_data() ignore its final parameter except when freeing data
|
|
that can have multiple instances (text, sPLT, unknowns).
|
|
Fixed a new bug in png_set_rows().
|
|
Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
|
|
Added png_set_invalid() function.
|
|
Fixed incorrect illustrations of png_destroy_write_struct() in example.c.
|
|
|
|
Version 1.0.7beta15 [May 30, 2000]
|
|
Revised the deliberately erroneous Linux setjmp code in pngconf.h to produce
|
|
fewer error messages.
|
|
Rearranged checks for Z_OK to check the most likely path first in pngpread.c
|
|
and pngwutil.c.
|
|
Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
|
|
in libpng.txt/libpng.3 the need for applications to check this.
|
|
Changed names of png_default_*() functions in pngtest to pngtest_*().
|
|
Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
|
|
Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
|
|
Set each pointer to NULL after freeing it in png_free_data().
|
|
Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
|
|
macro that conflicts with libpng's png_color_16.index. (Dimitri
|
|
Papadapoulos)
|
|
Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).
|
|
|

|
|
Revised the workaround of AIX string.h "index" bug.
|
|
Added a check for overlength PLTE chunk in pngrutil.c.
|
|
Added PNG_NO_POINTER_INDEXING macro to use array-indexing instead of pointer
|
|
indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.

Added a warning in png_decompress_chunk() when it runs out of data, e.g.
|
|

|
|
for pcal_params.

|
|
reading an interlaced file, to avoid a possible UMR.
|
|
Undid revision of PNG_NO_STDIO version of png_write_flush(). Users
|

having trouble with fflush() can build with PNG_NO_WRITE_FLUSH defined
|
|
or supply their own flush_fn() replacement.
|

|
|
|
|
Version 1.4.0beta54 [April 13, 2009]

|
Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
|
|
application code writers to bypass the check for multiple inclusion
|
|
of setjmp.h when they know that it is safe to ignore the situation.
|
|
Eliminated internal use of setjmp() in pngread.c and pngwrite.c
|
|
Reordered ancillary chunks in pngtest.png to be the same as what
|
|
pngtest now produces, and made some cosmetic changes to pngtest output.

|
|
"shadowed declaration" warning from gcc-4.3.3.
|
|
Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration"
|
|
warning about a global "gamma" variable in math.h on some platforms.
|
|
|
|
Version 1.4.0beta57 [May 2, 2009]
|
|
Removed prototype for png_freeptr() that was added in libpng-1.4.0beta24
|
|
but was never defined (again).

|
|
decoder, based on contrib/gregbook with embedded libpng and zlib.
|
|
|
|
Version 1.4.0beta61 [May 20, 2009]
|
|
In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there
|
|
is only one makefile in those directories, and revised the README files
|
|
accordingly.
|
|
More reformatting of comments, mostly to capitalize sentences.
|
|
|
|
Version 1.4.0beta62 [June 2, 2009]

Reformatted several remaining "else statement" into two lines.
|
|
Added a section to the libpng documentation about using png_get_io_ptr()
|

|
|
Version 1.4.0beta63 [June 15, 2009]
|
|
Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()

multiple times and to specify the sample order in the tRNS chunk,
|
|
because the ISO PNG specification has a typo in the tRNS table.
|
|
Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to
|
|
PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism
|
|
available for ignoring known chunks even when not saving unknown chunks.
|
|
Adopted preference for consistent use of "#ifdef" and "#ifndef" versus
|
|
"#if defined()" and "if !defined()" where possible.
|
|
|
|
Version 1.4.0beta64 [June 24, 2009]
|
|
Eliminated PNG_LEGACY_SUPPORTED code.
|
|
Moved the various unknown chunk macro definitions outside of the

|
|
|
|
Version 1.4.0beta69 [July 25, 2009]

Simplified the new filter-selection test. This runs faster in the
|
|
common "PNG_ALL_FILTERS" and PNG_FILTER_NONE cases.

|
|
Eliminated unused png_ptr->row_buf_size
|
|
|

|
|
Updated the "xcode" project (Alam Arias).

|
|
Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and

PNG_ALLOCATED macros to detect deprecated direct access to the
|
|
png_struct or info_struct members and other deprecated usage in
|
|
applications (John Bowler).
|
|
Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
|
|
to prevent warnings about direct access to png structs by libpng
|
|
functions while building libpng. They need to be tested, especially
|
|
those using compilers other than gcc.
|
|
Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
|
|
They should work but still need to be updated to remove

|
|
Removed dependency of pngtest.o on pngpriv.h in the makefiles.
|
|

|
|
|
|
Version 1.4.0beta95 [November 10, 2009]
|
|
Changed png_check_sig() to !png_sig_cmp() in contrib programs.
|
|
Added -DPNG_CONFIGURE_LIBPNG to contrib/pngminm/*/makefile

|
Removed the deprecated png_check_sig() function/macro.
|
|
Removed recently removed function names from scripts/*.def
|
|
Revised pngtest.png to put chunks in the same order written by pngtest
|
|
(evidently the same change made in libpng-1.0beta54 was lost).
|
|
Added PNG_PRIVATE macro definition in pngconf.h for possible future use.
|
|
|
|
Version 1.4.0beta97 [November 13, 2009]
|
|
Restored pngtest.png to the libpng-1.4.0beta7 version.

|
|
Moved libpng-config.in and libpng.pc-configure.in out of the scripts
|
|
directory, to libpng-config.in and libpng-pc.in, respectively, and
|
|
modified Makefile.am and configure.ac accordingly. Now "configure"
|
|
needs nothing from the "scripts" directory.
|
|
Avoid redefining PNG_CONST in pngconf.h
|
|
|

|
|
accidentally deleted from the zip and 7z distributions when the xcode
|
|
project was added.
|
|
|
|
Version 1.4.0beta102 [November 18, 2009]
|

|
|
Fixed a typo in projects/visualc6/pngtest.dsp, introduced in beta100.
|

|
Align row_buf on 16-byte boundary in memory.
|
|
Restored the PNG_WRITE_FLUSH_AFTER_IEND_SUPPORTED guard around the call
|
|
to png_flush() after png_write_IEND(). See 1.4.0beta32, 1.4.0beta50
|
|
changes above and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES. Someone
|
|
needs this feature.
|
|
Make the 'png_jmpbuf' macro expand to a call that records the correct
|
|
longjmp function as well as returning a pointer to the setjmp
|
|
jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
|
|
(John Bowler)
|
|
|
|
Version 1.4.0beta104 [November 22, 2009]
|
|
Removed png_longjmp_ptr from scripts/*.def and libpng.3
|
|
Rebuilt configure scripts with autoconf-2.65
|
|
|
|
Version 1.4.0beta105 [November 25, 2009]
|
|
Use fast integer PNG_DIVIDE_BY_255() or PNG_DIVIDE_BY_65535()
|
|
to accomplish alpha premultiplication when
|
|
PNG_READ_COMPOSITE_NODIV_SUPPORTED is defined.
|
|
Changed "/255" to "/255.0" in background calculations to make it clear
|
|
that the 255 is used as a double.
|
|
|
|
Version 1.4.0beta106 [November 27, 2009]
|
|

|
|
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/libpng15 instead of in
|
|
$prefix/include/libpng/libpng15.
|
|
|
|
Version 1.4.0beta108 [December 11, 2009]
|
|
Removed leftover "-DPNG_CONFIGURE_LIBPNG" from 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).
|
|
|
|
Version 1.4.0beta109 [December 13, 2009]
|
|
Added "bit_depth" parameter to the private png_build_gamma_table() function.
|
|
Pass bit_depth=8 to png_build_gamma_table() when bit_depth is 16 but the
|
|
PNG_16_TO_8 transform has been set, to avoid unnecessary build of 16-bit
|
|
tables.
|
|
|
|
Version 1.4.0rc02 [December 20, 2009]
|
|
Declared png_cleanup_needed "volatile" in pngread.c and pngwrite.c

|
|
|
Version 1.4.0rc04 [December 25, 2009]
|
|
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.
|
|
|
|
Version 1.4.0rc05 [December 25, 2009]

|
|
links as configure, except for libpng.la and libpng14.la.
|

Added png_set|get_chunk_malloc_max() functions.
|
|
|
|
Version 1.4.1beta05 [January 26, 2010]

Relocated "int k" declaration in pngtest.c to minimize its scope.
|
|
|
|
Version 1.4.1beta06 [January 28, 2010]
|
|
Revised png_decompress_chunk() to use a two-pass method suggested by
|
|
John Bowler.
|
|
|
|
Version 1.4.1beta07 [February 6, 2010]
|
|
Folded some long lines in the source files.
|
|
Added defineable PNG_USER_CHUNK_CACHE_MAX, PNG_USER_CHUNK_MALLOC_MAX,
|
|
and a PNG_USER_LIMITS_SUPPORTED flag.
|
|
Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
|
|

|
|
|

Minor cleanup and updating of dates and copyright year.
|

Version 1.5.0beta01 [February 7, 2010]
|
|
Moved declaration of png_struct into private pngstruct.h and png_info
|
|
into pnginfo.h
|
|
|
|
Version 1.4.1beta09 and 1.5.0beta02 [February 7, 2010]
|
|
Reverted to original png_push_save_buffer() code.
|
|
|
|
Version 1.4.1beta10 and 1.5.0beta03 [February 8, 2010]
|
|
Return allocated "old_buffer" in png_push_save_buffer() before
|
|
calling png_error(), to avoid a potential memory leak.
|
|
Updated configure script to use SO number 15.
|
|
|
|
Version 1.5.0beta04 [February 9, 2010]
|
|
Removed malformed "incomplete struct declaration" of png_info from png.h
|
|
|
|
Version 1.5.0beta05 [February 12, 2010]
|
|
Removed PNG_DEPSTRUCT markup in pngstruct.h and pnginfo.h, and undid the
|
|
linewrapping that it entailed.
|
|
Revised comments in pngstruct.h and pnginfo.h and added pointers to
|
|
the libpng license.
|
|
Changed PNG_INTERNAL to PNG_EXPOSE_INTERNAL_STRUCTURES
|
|
Removed the cbuilder5 project, which has not been updated to 1.4.0.
|

|
Version 1.4.1beta12 and 1.5.0beta06 [February 14, 2010]
|
|
Fixed type declaration of png_get_chunk_malloc_max() in pngget.c (Daisuke
|
|
Nishikawa)
|
|
|
|
Version 1.5.0beta07 [omitted]
|
|
|
|
Version 1.5.0beta08 [February 19, 2010]
|
|
Changed #ifdef PNG_NO_STDIO_SUPPORTED to #ifdef PNG_NO_CONSOLE_IO_SUPPORTED
|
|
wherever png_snprintf() is used to construct error and warning messages.
|
|
Noted in scripts/makefile.mingw that it expects to be run under MSYS.
|
|
Removed obsolete unused MMX-querying support from contrib/gregbook
|
|
Added exported png_longjmp() function.
|
|
Removed the AIX redefinition of jmpbuf in png.h
|
|
Added -D_ALLSOURCE in configure.ac, makefile.aix, and CMakeLists.txt
|
|
when building on AIX.
|
|
|
|
Version 1.5.0beta09 [February 19, 2010]
|
|
Removed -D_ALLSOURCE from configure.ac, makefile.aix, and CMakeLists.txt.
|
|
Changed the name of png_ptr->jmpbuf to png_ptr->png_jmpbuf in pngstruct.h
|
|
|
|
Version 1.5.0beta10 [February 25, 2010]
|
|
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
|
|
Removed replacement error handlers from contrib/gregbook. Because of
|
|
the new png_longjmp() function they are no longer needed.
|
|
|
|
Version 1.5.0beta11 [March 6, 2010]
|
|
Removed checking for already-included setjmp.h from pngconf.h
|
|
Fixed inconsistent indentations and made numerous cosmetic changes.
|
|
Revised the "SEE ALSO" style of libpng.3, libpngpf.3, and png.5
|
|
|
|
Version 1.5.0beta12 [March 9, 2010]
|
|
Moved "#include png.h" inside pngpriv.h and removed "#include png.h" from
|
|
the source files, along with "#define PNG_EXPOSE_INTERNAL_STRUCTURES"
|
|
and "#define PNG_NO_PEDANTIC_WARNINGS" (John Bowler).
|
|
Created new pngdebug.h and moved debug definitions there.
|
|
|
|
Version 1.5.0beta13 [March 10, 2010]
|
|
Protect pngstruct.h, pnginfo.h, and pngdebug.h from being included twice.
|
|
Revise the "#ifdef" blocks in png_inflate() so it will compile when neither
|
|
PNG_USER_CHUNK_MALLOC_MAX nor PNG_SET_CHUNK_MALLOC_LIMIT_SUPPORTED
|
|
is defined.
|
|
Removed unused png_measure_compressed_chunk() from pngpriv.h and libpngpf.3
|
|
Moved the 'config.h' support from pngconf.h to pngpriv.h
|
|
Removed PNGAPI from the png_longjmp_ptr typedef.
|
|
Eliminated dependence of pngtest.c on the private pngdebug.h file.
|
|
Make all png_debug macros into *unterminated* statements or
|
|
expressions (i.e. a trailing ';' must always be added) and correct
|
|
the format statements in various png_debug messages.
|
|
|
|
Version 1.5.0beta14 [March 14, 2010]
|
|
Removed direct access to png_ptr->io_ptr from the Windows code in pngtest.c
|
|
Revised Makefile.am to account for recent additions and replacements.
|
|
Corrected CE and OS/2 DEF files (scripts/png*def) for symbols removed and
|
|
added ordinal numbers to the Windows DEF file and corrected the duplicated
|
|
ordinal numbers on CE symbols that are commented out.
|
|
Added back in export symbols that can be present in the Windows build but
|
|
are disabled by default.
|
|
PNG_EXPORT changed to include an 'ordinal' field for DEF file generation.
|
|
PNG_CALLBACK added to make callback definitions uniform. PNGAPI split
|
|
into PNGCAPI (base C form), PNGAPI (exports) and PNGCBAPI (callbacks),
|
|
and appropriate changes made to all files. Cygwin builds re-hinged to
|
|
allow procedure call standard changes and to remove the need for the DEF
|
|
file (fixes build on Cygwin).
|
|
Enabled 'attribute' warnings that are relevant to library APIs and callbacks.
|
|
Changed rules for generation of the various symbol files and added a new
|
|
rule for a DEF file (which is also added to the distribution).
|
|
Updated the symbol file generation to stop it adding spurious spaces
|
|
to EOL (coming from preprocessor macro expansion). Added a facility
|
|
to join tokens in the output and rewrite *.dfn to use this.
|
|
Eliminated scripts/*.def in favor of libpng.def; updated projects/visualc71
|
|
and removed scripts/makefile.cygwin.
|
|
Made PNG_BUILD_DLL safe: it can be set whenever a DLL is being built.
|
|
Removed the include of sys/types.h - apparently unnecessary now on the
|
|
platforms on which it happened (all but Mac OS and RISC OS).
|
|
Moved the Mac OS test into pngpriv.h (the only place it is used.)
|
|
|
|
Version 1.5.0beta15 [March 17, 2010]
|
|
Added symbols.chk target to Makefile.am to validate the symbols in png.h
|
|
against the new DEF file scripts/symbols.def.
|
|
Changed the default DEF file back to pngwin.def.
|
|
Removed makefile.mingw.
|
|
Eliminated PNG_NO_EXTERN and PNG_ALL_EXTERN
|
|
|
|
Version 1.5.0beta16 [April 1, 2010]
|
|
Make png_text_struct independent of PNG_iTXt_SUPPORTED, so that
|
|
fields are initialized in all configurations. The READ/WRITE
|
|
macros (PNG_(READ|WRITE)_iTXt_SUPPORTED) still function as
|
|
before to disable code to actually read or write iTXt chunks
|
|
and iTXt_SUPPORTED can be used to detect presence of either
|
|
read or write support (but it is probably better to check for
|
|
the one actually required - read or write.)
|
|
Combined multiple png_warning() calls for a single error.
|
|
Restored the macro definition of png_check_sig().
|
|
|
|
Version 1.5.0beta17 [April 17, 2010]
|
|
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
|
|
Documented the fact that png_set_dither() was disabled since libpng-1.4.0.
|
|
Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect
|
|
more accurately what it actually does. At the same time, renamed
|
|
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to
|
|
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
|
|
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
|
|
Freeze build-time only configuration in the build.
|
|
In all prior versions of libpng most configuration options
|
|
controlled by compiler #defines had to be repeated by the
|
|
application code that used libpng. This patch changes this
|
|
so that compilation options that can only be changed at build
|
|
time are frozen in the build. Options that are compiler
|
|
dependent (and those that are system dependent) are evaluated
|
|
each time - pngconf.h holds these. Options that can be changed
|
|
per-file in the application are in png.h. Frozen options are
|
|
in the new installed header file pnglibconf.h (John Bowler)
|
|
Removed the xcode project because it has not been updated to work
|
|
with libpng-1.5.0.
|
|
Removed the ability to include optional pngusr.h
|
|
|
|
Version 1.5.0beta18 [April 17, 2010]
|
|
Restored the ability to include optional pngusr.h
|
|
Moved replacements for png_error() and png_warning() from the
|
|
contrib/pngminim project to pngerror.c, for use when warnings or
|
|
errors are disabled via PNG_NO_WARN or PNG_NO_ERROR_TEXT, to avoid
|
|
storing unneeded error/warning text.
|
|
Updated contrib/pngminim project to work with the new pnglibconf.h
|
|
Added some PNG_NO_* defines to contrib/pngminim/*/pngusr.h to save space.
|
|
|
|
Version 1.5.0beta19 [April 24, 2010]
|
|
Added PNG_{READ,WRITE}_INT_FUNCTIONS_SUPPORTED. This allows the functions
|
|
to read and write ints to be disabled independently of PNG_USE_READ_MACROS,
|
|
which allows libpng to be built with the functions even though the default
|
|
is to use the macros - this allows applications to choose at app build
|
|
time whether or not to use macros (previously impossible because the
|
|
functions weren't in the default build.)
|
|
Changed Windows calling convention back to __cdecl for API functions.
|
|
For Windows/x86 platforms only:
|
|
__stdcall is no longer needed for Visual Basic, so libpng-1.5.0 uses
|
|
__cdecl throughout (both API functions and callbacks) on Windows/x86
|
|
platforms.
|
|
Replaced visualc6 and visualc71 projects with new vstudio project
|
|
Relaxed the overly-restrictive permissions of some files.
|
|
|
|
Version 1.5.0beta20 [April 24, 2010]
|
|
Relaxed more overly-restrictive permissions of some files.
|
|
|
|
Version 1.5.0beta21 [April 27, 2010]
|
|
Removed some unwanted binary bytes and changed CRLF to NEWLINE in the new
|
|
vstudio project files, and some trivial editing of some files in the
|
|
scripts directory.
|
|
Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in
|
|
contrib/pngminim/decoder/pngusr.h to make a smaller decoder application.
|
|
|
|
Version 1.5.0beta22 [April 28, 2010]
|
|
Fixed dependencies of GET_INT_32 - it does not require READ_INT_FUNCTIONS
|
|
because it has a macro equivalent.
|
|
Improved the options.awk script; added an "everything off" option.
|
|
Revised contrib/pngminim to use the "everything off" option in pngusr.dfa.
|
|
|
|
Version 1.5.0beta23 [April 29, 2010]
|
|
Corrected PNG_REMOVED macro to take five arguments.
|
|
The macro was documented with two arguments (name,ordinal), however
|
|
the symbol checking .dfn files assumed five arguments. The five
|
|
argument form seems more useful so it is changed to that.
|
|
Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED
|
|
in gregbook/readpng2.c
|
|
Corrected protection of png_get_user_transform_ptr. The API declaration in
|
|
png.h is removed if both READ and WRITE USER_TRANSFORM are turned off
|
|
but was left defined in pngtrans.c
|
|
Added logunsupported=1 to cause pnglibconf.h to document disabled options.
|
|
This makes the installed pnglibconf.h more readable but causes no
|
|
other change. The intention is that users of libpng will find it
|
|
easier to understand if an API they need is missing.
|
|
Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined.
|
|
Removed dummy_inflate.c from contrib/pngminim/encoder
|
|
Removed contrib/pngminim/*/gather.sh; gathering is now done in the makefile.
|
|
|
|
Version 1.5.0beta24 [May 7, 2010]
|
|
Use bitwise "&" instead of arithmetic mod in pngrutil.c calculation of the
|
|
offset of the png_ptr->rowbuf pointer into png_ptr->big_row_buf.
|
|
Added more blank lines for readability.
|
|
|
|
Version 1.5.0beta25 [June 18, 2010]
|
|
In pngpread.c: png_push_have_row() add check for new_row > height
|
|
Removed the now-redundant check for out-of-bounds new_row from example.c
|
|
|
|
Version 1.5.0beta26 [June 18, 2010]
|
|
In pngpread.c: png_push_process_row() add check for too many rows.
|
|
|
|
Version 1.5.0beta27 [June 18, 2010]
|
|
Removed the check added in beta25 as it is now redundant.
|
|
|
|
Version 1.5.0beta28 [June 20, 2010]
|
|
Rewrote png_process_IDAT_data to consistently treat extra data as warnings
|
|
and handle end conditions more cleanly.
|
|
Removed the new (beta26) check in png_push_process_row().
|
|
|
|
Version 1.5.0beta29 [June 21, 2010]
|
|
Revised scripts/options.awk to work on Sunos (but still doesn't work)
|
|
Added comment to options.awk and contrib/pngminim/*/makefile to try nawk.
|
|
|
|
Version 1.5.0beta30 [June 22, 2010]
|
|
Stop memory leak when reading a malformed sCAL chunk.
|
|
|
|
Version 1.5.0beta31 [June 26, 2010]
|
|
Revised pngpread.c patch of beta28 to avoid an endless loop.
|
|
Removed some trailing blanks.
|
|
|
|
Version 1.5.0beta32 [June 26, 2010]
|
|
Removed leftover scripts/options.patch and scripts/options.rej
|
|
|
|
Version 1.5.0beta33 [July 6, 3010]
|
|
Made FIXED and FLOATING options consistent in the APIs they enable and
|
|
disable. Corrected scripts/options.awk to handle both command line
|
|
options and options specified in the .dfa files.
|
|
Changed char *msg to PNG_CONST char *msg in pngrutil.c
|
|
Make png_set_sRGB_gAMA_and_cHRM set values using either the fixed or
|
|
floating point APIs, but not both.
|
|
Reversed patch to remove error handler when the jmp_buf is stored in the
|
|
main program structure, not the png_struct.
|
|
The error handler is needed because the default handler in libpng will
|
|
always use the jmp_buf in the library control structure; this is never
|
|
set. The gregbook code is a useful example because, even though it
|
|
uses setjmp/longjmp, it shows how error handling can be implemented
|
|
using control mechanisms not directly supported by libpng. The
|
|
technique will work correctly with mechanisms such as Microsoft
|
|
Structure Exceptions or C++ exceptions (compiler willing - note that gcc
|
|
does not by default support interworking of C and C++ error handling.)
|
|
Reverted changes to call png_longjmp in contrib/gregbook where it is not
|
|
appropriate. If mainprog->jmpbuf is used by setjmp, then png_longjmp
|
|
cannot be used.
|
|
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" {')
|
|
|
|
Version 1.5.0beta34 [July 12, 2010]
|
|
Put #ifndef PNG_EXTERN, #endif around the define PNG_EXTERN in pngpriv.h
|
|
|
|
Version 1.5.0beta35 [July 24, 2010]
|
|
Removed some newly-added TAB characters.
|
|
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
|
|
|
|
Version 1.5.0beta36 [July 29, 2010]
|
|
Patches by John Bowler:
|
|
Fixed point APIs are now supported throughout (no missing APIs).
|
|
Internal fixed point arithmetic support exists for all internal floating
|
|
point operations.
|
|
sCAL validates the floating point strings it is passed.
|
|
Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2
|
|
Two new APIs exist to get the number of passes without turning on the
|
|
PNG_INTERLACE transform and to get the number of rows in the current
|
|
pass.
|
|
A new test program, pngvalid.c, validates the gamma code.
|
|
Errors in the 16 bit gamma correction (overflows) have been corrected.
|
|
cHRM chunk testing is done consistently (previously the floating point
|
|
API bypassed it, because the test really didn't work on FP, now the test
|
|
is performed on the actual values to be stored in the PNG file so it
|
|
works in the FP case too.)
|
|
Most floating point APIs now simply call the fixed point APIs after
|
|
converting the values to the fixed point form used in the PNG file.
|
|
The standard headers no longer include zlib.h, which is currently only
|
|
required for pngstruct.h and can therefore be internal.
|
|
Revised png_get_int_32 to undo the PNG two's complement representation of
|
|
negative numbers.
|
|
|
|
Version 1.5.0beta37 [July 30, 2010]
|
|
Added a typecast in png_get_int_32() in png.h and pngrutil.h to avoid
|
|
a compiler warning.
|
|
Replaced oFFs 0,0 with oFFs -10,20 in pngtest.png
|
|
|
|
Version 1.5.0beta38 [July 31, 2010]
|
|
Implemented remaining "_fixed" functions.
|
|
Corrected a number of recently introduced warnings mostly resulting from
|
|
safe but uncast assignments to shorter integers. Also added a zlib
|
|
VStudio release library project because the latest zlib Official Windows
|
|
build does not include such a thing.
|
|
Revised png_get_int_16() to be similar to png_get_int_32().
|
|
Restored projects/visualc71.
|
|
|
|
Version 1.5.0beta39 [August 2, 2010]
|
|
VisualC/GCC warning fixes, VisualC build fixes
|
|
The changes include support for function attributes in VC in addition to
|
|
those already present in GCC - necessary because without these some
|
|
warnings are unavoidable. Fixes include signed/unsigned fixes in
|
|
pngvalid and checks with gcc -Wall -Wextra -Wunused.
|
|
VC requires function attributes on function definitions as well as
|
|
declarations, PNG_FUNCTION has been added to enable this and the
|
|
relevant function definitions changed.
|
|
|
|
Version 1.5.0beta40 [August 6, 2010]
|
|
Correct use of _WINDOWS_ in pngconf.h
|
|
Removed png_mem_ #defines; they are no longer used.
|
|
Added the sRGB chunk to pngtest.png
|
|
|
|
Version 1.5.0beta41 [August 11, 2010]
|
|
Added the cHRM chunk to pngtest.png
|
|
Don't try to use version-script with cygwin/mingw.
|
|
Revised contrib/gregbook to work under cygwin/mingw.
|
|
|
|
Version 1.5.0beta42 [August 18, 2010]
|
|
Add .dll.a to the list of extensions to be symlinked by Makefile.am (Yaakov)
|
|
Made all API functions that have const arguments and constant string
|
|
literal pointers declare them (John Bowler).
|
|
|
|
Version 1.5.0beta43 [August 20, 2010]
|
|
Removed spurious tabs, shorten long lines (no source change)
|
|
Also added scripts/chkfmt to validate the format of all the files that can
|
|
reasonably be validated (it is suggested to run "make distclean" before
|
|
checking, because some machine generated files have long lines.)
|
|
Reformatted the CHANGES file to be more consistent throughout.
|
|
Made changes to address various issues identified by GCC, mostly
|
|
signed/unsigned and shortening problems on assignment but also a few
|
|
difficult to optimize (for GCC) loops.
|
|
Fixed non-GCC fixed point builds. In png.c a declaration was misplaced
|
|
in an earlier update. Fixed to declare the auto variables at the head.
|
|
Use cexcept.h in pngvalid.c.
|
|
|
|
Version 1.5.0beta44 [August 24, 2010]
|
|
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.
|
|
Changed PNG_LIB_NAME from pngNN to libpngNN in CMakeLists.txt (Philip Lowman)
|
|
Implemented memory checks within pngvalid
|
|
Reformatted/rearranged pngvalid.c to assist use of progressive reader.
|
|
Check interlaced images in pngvalid
|
|
Clarified pngusr.h comments in pnglibconf.dfa
|
|
Simplified the pngvalid error-handling code now that cexcept.h is in place.
|
|
Implemented progressive reader in pngvalid.c for standard tests
|
|
Implemented progressive read in pngvalid.c gamma tests
|
|
Turn on progressive reader in pngvalid.c by default and tidy code.
|
|
|
|
Version 1.5.0beta45 [August 26, 2010]
|
|
Added an explicit make step to projects/vstudio for pnglibconf.h
|
|
Also corrected zlib.vcxproj into which Visual Studio had introduced
|
|
what it calls an "authoring error". The change to make pnglibconf.h
|
|
simply copies the file; in the future it may actually generate the
|
|
file from scripts/pnglibconf.dfa as the other build systems do.
|
|
Changed pngvalid to work when floating point APIs are disabled
|
|
Renamed the prebuilt scripts/pnglibconf.h to scripts/pnglibconf.h.prebuilt
|
|
Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX
|
|
in pngpriv.h in case the user neglected to define them in their pngusr.h
|
|
|
|
Version 1.5.0beta46 [August 28, 2010]
|
|
Added new private header files to libpng_sources in CMakeLists.txt
|
|
Added PNG_READ_16BIT, PNG_WRITE_16BIT, and PNG_16BIT options.
|
|
Added reference to scripts/pnglibconf.h.prebuilt in the visualc71 project.
|
|
|
|
Version 1.5.0beta47 [September 11, 2010]
|
|
Fixed a number of problems with 64-bit compilation reported by Visual
|
|
Studio 2010 (John Bowler).
|
|
|
|
Version 1.5.0beta48 [October 4, 2010]
|
|
Updated CMakeLists.txt (Philip Lowman).
|
|
Revised autogen.sh to recognize and use $AUTOCONF, $AUTOMAKE, $AUTOHEADER,
|
|
$AUTOPOINT, $ACLOCAL and $LIBTOOLIZE
|
|
Fixed problem with symbols creation in Makefile.am which was assuming that
|
|
all versions of ccp write to standard output by default (Martin Banky). The
|
|
bug was introduced in libpng-1.2.9beta5.
|
|
Removed unused mkinstalldirs.
|
|
|
|
Version 1.5.0beta49 [October 8, 2010]
|
|
Undid Makefile.am revision of 1.5.0beta48.
|
|
|
|
Version 1.5.0beta50 [October 14, 2010]
|
|
Revised Makefile.in to account for mkinstalldirs being removed.
|
|
Added some "(unsigned long)" typecasts in printf statements in pngvalid.c.
|
|
Suppressed a compiler warning in png_handle_sPLT().
|
|
Check for out-of-range text compression mode in png_set_text().
|
|
|
|
Version 1.5.0beta51 [October 15, 2010]
|
|
Changed embedded dates to "(PENDING RELEASE) in beta releases (and future
|
|
rc releases) to minimize the difference between releases.
|
|
|
|
Version 1.5.0beta52 [October 16, 2010]
|
|
Restored some of the embedded dates (in png.h, png.c, documentation, etc.)
|
|
|
|
Version 1.5.0beta53 [October 16, 2010]
|
|
Updated INSTALL to mention using "make maintainer-clean" and to remove
|
|
obsolete statement about a custom ltmain.sh
|
|
Disabled "color-tests" by default in Makefile.am so it will work with
|
|
automake versions earlier than 1.11.1
