2018-08-28Undefine PNG_READ_OPT_PLTE_SUPPORTEDLeon Scroggins III
Bug: 113211371 Test: not feasible - this prevents out of bounds read With PNG_READ_OPT_PLTE_SUPPORTED defined, a PLTE chunk following a tRNS chunk will negate the tRNS chunk for an image which is not paletted. The result is that we may read out of bounds. Change-Id: I4c6032e077b220f8349ab9e7c4102c460d1a7ea2
2017-10-06Update to 1.6.34Leon Scroggins III
Test: Covered by existing tests. This is the same version we will use in Chromium: https://chromium-review.googlesource.com/c/chromium/src/+/704209 https://github.com/glennrp/libpng/commit/edef058e180be435afd8feebb742a22360a7fa3f (included in this revision) moved the SSE opts directly into the main libpng source, so contrib/intel/intel_sse.patch is no longer necessary, as its changes are already included. Adds *all* code, rather than selecting just the code we use. Other changes: - README.android: - Update version - Android.mk -> Android.bp - Remove no longer relevant comment about applying the intel patch - Remove comment about deleting unused files - README.version: - Update version and source link Change-Id: Ib24cfcfec3e2f63eed8b3b9f0920b1018b30dd64

2016-10-16libpng: Upgrade to 1.6.25Alex Naidis
The changes from 1.6.22 (beta) to 1.6.25 (final) include many general fixes, fixes for memory leak issues and optimizations in order to improve performance. Also upstream added support for the MIPS platform. Support for Intel SSE isn't built in any more. For support a patch in contrib/intel/intel_sse.patch has to be applied. This patch additionally documents this in README.android as an Android specific addition. The patch for Intel SSE support from upstream applied cleanly. Libpng 1.6.25 released on September 1, 2016. Test: built for ARM and checked whether NEON optimizations were compiled built for x86/x86_64 and checked whether SSE optimizations were compiled Change-Id: If647f42a1fb4d7022286010d262d287dac4030df Signed-off-by: Alex Naidis <alex.naidis@linux.com>

Nobody is listening to the warnings, and it results in a bunch of: libpng warning: iCCP: Not recognizing known sRGB profile that has been edited libpng warning: iCCP: known incorrect sRGB profile Turn off PNG_WARNINGS_SUPPORTED to hide these.
