My game loads PNG files, and it keeps printing 'libpng warning: iCCP: known incorrect sRGB profile', which is very annoying for debugging.
I know there must be something wrong with my PNG files. But the PNG files are not maintained by me.

I just want to disable this warning. How to do it? Thanks.

Recompile libpng.  I've had that issue before and it's just a precompiled binary issue. On 19 Jul 2014 09:41, "RunningOn" wrote:

If you're on Linux, install ImageMagick, then run

find . -iname "*.png" | while read f; do convert "${f}" -strip "${f}"; done



in the directory of your assets. This will fix the png's themselves.

Where is libpng? in the source of SDL2_image?

It's not a precompiled binary issue; since version 1.6, libpng will emit these
warnings when it encounters an invalid color profile, you most likey just
compiled an older version from source instead. This annoyance is not going
to go away unless the actual png's are sanitized.

libpng doesn't provide a way to have the warnings redirected somewhere
else? Forcing all that through the console is annoying.

as far as i know you need to downgrade to a past version of libpng, but my advice would be to create a script that convert all the images to a correct format. you can use Python with PIL to do the job, or ImageMagick if available. Something like this.

Huh, recompiling worked for me about a year ago, but that's interesting.  Thanks for the tip
