PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined.
Removed some extraneous "-I" from contrib/pngminus/makefile.std
Changed the PNG_sRGB_INTENT macros in png.h to be consistent with PNG-1.2.
Change PNG_SRGB_INTENT to PNG_sRGB_INTENT in libpng.txt and libpng.3
version 1.0.5d [November 29, 1999]
Change PNG_SRGB_INTENT to PNG_sRGB_INTENT in libpng.txt and libpng.3
version libpng-1.0.5d November 29, 1999
Add type cast (png_const_charp) two places in png.c
Eliminated pngtypes.h; use macros instead to declare PNG_CHNK arrays.
Renamed "PNG_GLOBAL_ARRAYS" to "PNG_USE_GLOBAL_ARRAYS" and made available
to applications a macro "PNG_USE_LOCAL_ARRAYS".
#ifdef out all the new declarations when PNG_USE_GLOBAL_ARRAYS is defined.
Added PNG_EXPORT_VAR macro to accommodate making DLL's.
version libpng-1.0.5e November 30, 1999
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
#ifdef PNG_iTXt_SUPPORTED
png_text[i].lang = NULL;
#endif
Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned
offsets (Eric S. Raymond).
Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into
PNG_cHNK_SUPPORTED and combined the three types of PNG_text_SUPPORTED
macros, leaving the separate macros also available.
Removed comments on #endifs at the end of many short, non-nested #if-blocks.
version libpng-1.0.5f December 6, 1999
Changed makefile.solaris to issue a warning about potential problems when
the ucb "ld" is in the path ahead of the ccs "ld".
Removed "- [date]" from the "synopsis" line in libpng.3 and libpngpf.3.
Added sCAL chunk support (Eric S. Raymond).
version libpng-1.0.5g December 7, 1999
Fixed "png_free_spallettes" typo in png.h
Added code to handle new chunks in pngpread.c
Moved PNG_CHNK string macro definitions outside of PNG_NO_EXTERN block
Added "translated_key" to png_text structure and png_write_iTXt().
Added code in pngwrite.c to work around a newly discovered zlib bug.
version 1.0.5h [December 10, 1999]
NOTE: regarding the not for version 1.0.5e, the following must also
be included in your code:
png_text[i].translated_key = NULL;
Unknown chunk handling is now supported.
Option to eliminate all floating point support was added. Some new
fixed-point functions such as png_set_gAMA_fixed() were added.
