Use png_calloc() instead of png_malloc() to allocate big_row_buf when
|
||||
reading an interlaced file, to avoid a possible UMR.
|
||||
Undid recent revision of PNG_NO_STDIO version of png_write_flush(). Users

Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow
|
||||

|
||||
Eliminated internal use of setjmp() in pngread.c and pngwrite.c

|
||||
"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]

|
||||
progressive readers.
|
||||
Added contrib/pngminim/preader to demonstrate building minimal progressive
|
||||
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.
|
||||
|

|
||||
Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR()

|
||||
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]
|
||||

|
||||
|
||||
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.
|
||||
Removed extraneous declaration from the new call to png_read_gray_to_rgb()
|
||||
(bug introduced in libpng-1.4.0beta67).
|
||||
Fixed up xcode project (Alam Arias)
|
||||
|
||||
version 1.4.0beta70 [July 27, 2009]

|
||||

|
||||
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 1.4.0beta86 [October 9, 2009]
|
||||
Updated the "xcode" project (Alam Arias).
|
||||
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 1.4.0rc01 [October 19, 2009]
|
||||
Trivial cosmetic 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 1.4.0beta87 [October 30, 2009]
|
||||
Moved version 1.4.0 back into beta.

|
||||
as in libpng-1.4.0beta78 and later.

||||
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 1.2.41beta07 [October 21, 2009]
|
||||
Ported some cosmetic changes from libpng-1.4.0rc01, changing
|
||||

|
||||
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

|
||||
Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate.
|
||||
|
||||
version 1.4.0beta90 [November 2, 2009]
|
||||
Removed all remaining WIN32_WCE #ifdefs except those involving the
|
||||
time.h "tm" structure
|
||||
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 1.4.0beta91 [November 3, 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 1.4.0beta92 [November 4, 2009]
|
||||
version 1.2.41beta14 [November 8, 2009]
|
||||
versions 1.2.41beta05 through 1.2.41beta13 were abandoned.
|
||||
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
|
||||
Revised libpng*.txt to describe differences from 1.2.40 to 1.4.0 (instead
|
||||
of differences from 1.2.41 to 1.4.0)
|
||||
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
|
||||
|
||||
version 1.4.0beta93 [November 7, 2009]
|
||||
version 1.2.41beta15 [November 8, 2009]
|
||||
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
|
||||
@ -621,47 +137,29 @@ version 1.4.0beta93 [November 7, 2009]
|
||||
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
|
||||
references to pnggccrd.c or pngvcrd.c and ASM building.
|
||||
Added README.txt to the beos, cbuilder5, netware, and xcode projects warning
|
||||
that they need to be updated, to remove references to pnggccrd.c and
|
