libpng warning: Ignoring bad adaptive filter type

kill, libpng, warnings

Solution

The question gives insufficient information to provide a complete answer.

The "bad adaptive filter type" message means that the PNG file is either corrupted or was generated by a buggy encoder.

Each scanline of a PNG file begins with a "filter type" byte which must be 0, 1, 2, 3, or 4.

Problem

my app was killed,and the log :libpng warning: Ignoring bad adaptive filter type. I want to know the reason,and the solution.
