9b979b177b [devel] Added new types and internal functions for CIE RGB end point handling 
to pngpriv.h (functions yet to be implemented).

7b9796539d [devel] Prevent unexpected API exports from non-libpng DLLs on Windows. 
The "_DLL" is removed from the test of whether a DLL is being built.

ab63dd0892 [devel] Renamed png_set_chop_16() to png_set_strip_16(). 2011-06-17 20:41:19 -05:00
Glenn Randers-Pehrson
5f0b9276ec [devel] Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. 
If this is not enabled, png_set_strip_16() and png_do_scale_16_to_8()
aren't built.

550bab03fb [devel] Removed the ACCURATE and LEGACY options (they are no longer useable) 
Fixed some compiliation problems with scaling options.
 2011-06-14 06:17:26 -05:00
John Bowler
6a1dc2329a [devel] Removed string/memory macros that are no longer used 
and are not necessarily fully supportable, particularly png_strncpy and
png_snprintf.
 2011-06-11 06:58:46 -05:00
Glenn Randers-Pehrson
2d3fc1ca3b [devel] Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and 
PNG_AFTER_IDAT from pngpriv.h to png.h because they must be visible to
applications that call png_set_unknown_chunks().
 2011-05-10 23:48:00 -05:00
John Bowler
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
used for Macs - it's not a good idea to embed this in the ABI!
 2011-05-10 22:54:37 -05:00
John Bowler
d273ad2d0f [devel] Implementation of premultiplied alpha support: png_set_alpha_mode 
(libpng-manual.txt still to be updated, see png.h for documentation.)

af855e415d [devel] Remove some trailing blanks. 2011-05-07 10:54:28 -05:00
John Bowler
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.
 2011-05-05 17:35:39 -05:00
John Bowler
88b77cc6f3 [devel] Remove png_snprintf, add formatted warning messages. 
This change adds internal APIs to allow png_warning messages to have parameters
 without requiring the host OS to implelment snprintf.  As a side effect the
 dependency of the RFC1132 code on stdio is removed and PNG_NO_WARNINGS does
 actually work now.
 2011-05-05 06:49:55 -05:00
Glenn Randers-Pehrson
b3b7168077 [devel] Added appropriate feature test macros (_POSIX_SOURCE, _ISOC99_SOURCE) 
to ensure libpng sees the correct API.
 2011-05-03 22:30:19 -05:00
John Bowler
4a12f4a22a [devel] Cleanup of conditional compilation code and of background/gamma 
handling. Internal changes only except for a new option to avoid compiling
in the png_build_grayscale_palette API (which is not used at all internally.)
The main change is to move the transform tests (READ_TRANSFORMS,
WRITE_TRANSFORMS) up one level to the caller of the APIs.

4f108d8af6 [devel] Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX

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.

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.

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

a528fba7aa [devel] Enabled 'attribute' warnings that are relevant to library APIs

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.

eae8e36ec4 [devel] 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).

d29033f264 [master] Added macros to detect use of deprecated features. 
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).
  Added -DPNG_CONFIGURE_LIBPNG to the makefile CFLAGS, to prevent warnings
    about direct access to png structs by libpng functions while building
    libpng.
  Removed three direct references to read_info_ptr members in pngtest.c
    that were detected by the new PNG_DEPSTRUCT macro.
  Moved the png_debug macro definitions and the png_read_destroy(),
    png_write_destroy() and png_far_to_near() prototypes from png.h
    to pngpriv.h (John Bowler)
  Moved the synopsis lines for png_read_destroy(), png_write_destroy()
    png_debug(), png_debug1(), and png_debug2() from libpng.3 to libpngpf.3.
