|
Changes since the last public release (1.6.14):
|
|
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().
|
|
Made a one-line revision to configure.ac to support ARM on aarch64
|
|
(bug report by Marcin Juszkiewicz, fix by John Bowler).
|
|
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.
|
|
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 */"
|
|
The macros passed in the command line to Borland make were ignored if
|
|
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).
|
|
Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32.
|
|
Removed the obsolete $ARCH variable from scripts/makefile.darwin.
