similarly-named macros were already defined in makefiles. This behavior is different from POSIX make and other make programs. Surround the macro definitions with ifndef guards (Cosmin).

|
Changes since the last public release (1.6.14):
|
|
|
|
Version 1.6.15beta01 [October 29, 2014]
|
|
Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x !== 0)"
|
|
Simplified png_free_data().
|
|
Added missing "ptr = NULL" after some instances of png_free().
|
|
|
|
Version 1.6.15beta02 [November 1, 2014]
|
|
Changed remaining "if (!x)" to "if (x == 0)" and "if (x)" to "if (x !== 0)"
|
|
|
|
Version 1.6.15beta03 [November 3, 2014]
|
|
Added PNG_USE_ARM_NEON configuration flag (Marcin Juszkiewicz).
|
|
|
|
Version 1.6.15beta04 [November 4, 2014]
|
|
Removed new PNG_USE_ARM_NEON configuration flag and made a one-line
|
|
revision to configure.ac to support ARM on aarch64 instead (John Bowler).
|
|
|
|
Version 1.6.15beta05 [November 5, 2014]
|
|
Use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING in
|
|
example.c, pngtest.c, and applications in the contrib directory.
|
|
Avoid out-of-bounds memory access in png_user_version_check().
|
|
Simplified and future-proofed png_user_version_check().
|
|
Fixed GCC unsigned int->float warnings. Various versions of GCC
|
|
seem to generate warnings when an unsigned value is implicitly
|
|
converted to double. This is probably a GCC bug but this change
|
|
avoids the issue by explicitly converting to (int) where safe.
|
|
Free all allocated memory in pngimage. The file buffer cache was left
|
|
allocated at the end of the program, harmless but it causes memory
|
|
leak reports from clang.
|
|
Fixed array size calculations to avoid warnings. At various points
|
|
in the code the number of elements in an array is calculated using
|
|
sizeof. This generates a compile time constant of type (size_t) which
|
|
is then typically assigned to an (unsigned int) or (int). Some versions
|
|
of GCC on 64-bit systems warn about the apparent narrowing, even though
|
|
the same compiler does apparently generate the correct, in-range,
|
|
numeric constant. This adds appropriate, safe, casts to make the
|
|
warnings go away.
|
|
|
|
Version 1.6.15beta06 [November 6, 2014]
|
|
Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING
|
|
in the manual, example.c, pngtest.c, and applications in the contrib
|
|
directory. It was incorrect advice.
|
|
|
|
Version 1.6.15beta07 [November 7, 2014]
|
|
Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
|
|
needed by png_reciprocal2().
|
|
Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
|
|
png_do_swap().
|
|
Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
|
|
|
|
Version 1.6.15beta08 [November 8, 2014]
|
|
More housecleaning in *.h
|
|
|
|
Version 1.6.15rc01 [November 13, 2014]
|
|
|
|
Version 1.6.15rc02 [November 14, 2014]
|
|
The macros passed in the command line to Borland make are ignored if
|
|
similarly-named macros are already defined in makefiles. This behavior
|
|
is different from POSIX make and other make programs. Surround the
|
|
macro definitions with ifndef guards (Cosmin).
