fff1093227 [devel] Same situation with png_set_iCCP(). 2011-01-08 11:05:47 -06:00
Glenn Randers-Pehrson
9d23b40c24 [devel] Added a note in the manual that the type of the iCCP profile changed 
from png_charpp to png_bytepp in png_get_iCCP().  This change happened
in version 1.5.0beta36 but is not noted in the CHANGES.  Also, revised
the "synopsis" for png_get_iCCP() in libpng.3 accordingly.

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'.

a581556b17 [master] Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin) 
Moved reading of file signature into png_read_sig (Cosmin)
Fixed atomicity of chunk header serialization (Cosmin)
Added test for io_state in pngtest.c (Cosmin)
Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts.

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.

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).
 2010-08-19 07:01:09 -05:00
Glenn Randers-Pehrson
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.

Glenn Randers-Pehrson
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.

77396b63f9 [devel] 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.

4009a76e97 [devel] Implemented remaining "_fixed" functions and corrected warnings 
that were recently introduced, 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.

31aee0d0c0 [devel] 
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.

73e28ef13d [devel] 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.
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.)

9ee577c7f5 [devel] 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

c3d73f4da9 [devel] 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.)

862cb20ea6 [devel] 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 pnglconf.h

    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).
