aren't built.

cd3b0cc4d9 [devel] Fixed a problem in png_do_expand_palette() exposed by optimization in 
1.5.3beta06
  Also removed a spurious (totally unused and confusing) member from png_info.
  The palette expand optimization prevented expansion to an intermediate RGBA
    form if tRNS was present but alpha was marked to be stripped; this exposed
    a check for tRNS in png_do_expand_palette() which is inconsistent with the
    code elsewhere in libpng.

59a6c379dd [devel] Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. 
This allows pngvalid to build when ALPHA_MODE is not supported, which is
required if it is to build on libpng 1.4.

d2f0bc2d13 [devel] Improved gamma range checks and other things OpenWatcom warns about. 2011-06-11 06:42:06 -05:00
John Bowler
0eadc27cd6 [devel] Added projects/owatcom, an IDE project for OpenWatcom to replace 
scripts/makefile.watcom.  This project works with OpenWatcom 1.9. The
    IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
    The project is configurable, unlike the Visual Studio project, so long
    as the developer has an awk.

700c55036c [devel] Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro. 2011-06-10 23:26:03 -05:00
John Bowler
b2bee3374c [devel] Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is 
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
    wrong in 128 out of 65536 cases. Getting the right answer all the time
    without division is easy.
 2011-06-10 23:24:58 -05:00

cc2770850a [devel] Revised documentation about png_set_user_limits() to say that it can

png writing.

John Bowler
1921e6db90 [devel] Reversed earlier change of transformation order; move 
png_expand_16 back where it was before libpng-1.5.3beta07.
The change doesn't work because it requires 16 bit gamma tables when the code
only generates 8 bit ones.  This fails silently; the libpng code just doesn't
do any gamma correction.  Moving the tests back leaves the old, inaccurate, 8
bit gamma calculations, but these are clearly better than none!

cb0b29631f [devel] Documented png_set_alpha_mode(), other changes in libpng.3 and 
libpng-manual.txt.
  The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative
    parameters are supplied by the caller), while in the absence of cHRM
    sRGB/Rec 709 values are still used.
  The bKGD chunk no longer overwrites the background value set by
    png_set_background(), allowing the latter to be used before the file
    header is read. It never performed any useful function to override
    the default anyway.

2d3fc1ca3b [devel] Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and

f70c7d02e9 [devel] Added named value and 'flag' gamma support to png_set_gamma. Made a 
minor change from the previous (unreleased) ABI/API to hide the exact value

c5bef946b1 [devel] IDAT compression failed if preceded by a compressed text chunk 
This was because the attempt to reset the zlib stream in png_write_IDAT
happened after the first IDAT chunk had been deflated - much too late.
In this change internal functions are added to claim/release the z_stream
and, hopefully, make the code more robust.  Also deflateEnd checking is
added - previously libpng would ignore an error at the end of the stream.

b3edc73afa [devel] Changes to remove gcc warnings (John Bowler) 
Certain optional gcc warning flags resulted in warnings in libpng code.
With these changes only -Wconversion and -Wcast-qual cannot be turned on.
Changes are trivial rearrangements of code.  -Wconversion is not possible
for pngrutil.c (because of the widespread use of += et al on variables
smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
with pngwio.c and pngwutil.c because the 'write' callback and zlib
compression both fail to declare their input buffers with 'const'.

4f108d8af6 [devel] Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX 
in pngpriv.h in case the user forgot to define them in their pngusr.h.  This
means it is safe for people not building a DLL to omit these defines from pngusr.h.

b5b38edf30 [devel] 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.

8c037305e4 [devel] Updated CMakeLists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for 
installing libpng in /usr/lib64 (Funda Wang).  Also ported other recent
changes from libpng-1.4.4beta07:
  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)

67439c4701 [devel] Addressed various issues identified by GCC, mostly signed/unsigned 
and shortening problems on assignment but also a few difficult to optimize
(for GCC) loops (John Bowler).

a313751258 [devel] 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.

e600c51355 [devel]Made all API functions that have const arguments and constant string 
literal pointers declare them (John Bowler).
Many APIs did not change their arguments but were not declared using
PNG_CONST.  This change corrects this.  In a few cases APIs that return
constant string literal pointers have also been changed to declare this.
Unlike the argument change this may require app changes; however the
results could never be written to (the app would crash on some platforms
where strings are not writable), so this seems advisable.
