|
|
|
|
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).
|
|
|
|
version 0.96 [May, 1997]
|
|
fixed serious bug with < 8bpp images introduced in 0.95
|

|
|
fixed typecasts of "new_key", etc. (Andreas Dilger)
|
|
added RFC 1152 [sic] date support
|
|
fixed bug in gamma handling of 4-bit grayscale
|
|
added 2-bit grayscale gamma handling (Glenn R-P)

|
|
minor corrections in libpng.txt
|
|
added simple sRGB support (Glenn R-P)
|
|
easier conditional compiling, e.g. define PNG_READ/WRITE_NOT_FULLY_SUPPORTED;
|
|
all configurable options can be selected from command-line instead
|
|
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
|
|
repaired PNG_NO_STDIO behaviour
|
|
tested NODIV support and made it default behaviour (Greg Roelofs)
|
|
added "-m" option and PNGTEST_DEBUG_MEMORY to pngtest (John Bowler)

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

|
Changed type of num_hist from png_uint_32 to int (same as num_palette).
|
|
Added checks for rowbytes overflow, in case png_size_t is less than 32 bits.
|
|
Renamed makefile.elf to makefile.lnx.

Add parentheses for easier reading of pngget.c, fixed "||" should be "&&".
|

Touched up example.c to make more of it compileable, although the entire
|
|
file still can't be compiled (Willem van Schaik)
|
|
Fixed a bug in png_do_shift() (Bryan Tsai)

|
|
Corrected some bugs in the experimental weighted filtering heuristics.
|
|
Moved a misplaced pngrutil code block that truncates tRNS if it has more

|
|
Fixed a png_convert_to_rfc1123() bug that converts day 31 to 0 (Steve Eddins).

|
|
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()
|
|
and png_read_rows().
|
|
Added pngdll.mak and pngdef.pas to scripts directory, contributed by
|
|
Bob Dellaca, to make a png32bd.dll with Borland C++ 4.5
|
|
Fixed error in example.c with png_set_text: num_text is 3, not 2 (Guido V.)
|

|
|
the same structure.
|
|
Added a test such that png_do_gamma will be done when num_trans==0
|
|
for truecolor images that have defined a background. This corrects an
|
|
error that was introduced in libpng-0.90 that can cause gamma processing
|
|
to be skipped.
|
|
Added tests in png.h to include "trans" and "trans_values" in structures

|
|
Replaced and extended code that was removed from png_set_filler() in 1.0.1a.
|
|
Fixed a bug in png_do_filler() that made it fail to write filler bytes in
|
|
the left-most pixel of each row (Kevin Bracey).
|
|
Changed "static pngcharp tIME_string" to "static char tIME_string[30]"
|
|
in pngtest.c (Duncan Simpson).

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

|
|
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
|
|

|
|
PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED

|
|
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]

|
|
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.
|

|
|
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]

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
|
|
and mentioned the purposes of the two macros in libpng.txt/libpng.3.
|
|
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.
|
|
Removed superfluous prototype for png_set_itxt from png.h
|
|
Removed "else" from pngread.c, after png_error(), and changed "0" to "length".
|
|
Changed several png_errors about malformed ancillary chunks to png_warnings.
|
|
version 1.0.6g [April 24, 2000]
|
|
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).
|
|
version 1.0.7beta16 [June 4, 2000]
|
|
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.
