libpng warnings

Post by NoQ »

Not really a problem, just wondering if they mean anything.
Might it mean some of our texture files need fixing?

I have this in console log every time i start the game:

Code: Select all

libpng warning: iCCP: known incorrect sRGB profile

Re: libpng warnings

Post by vexed »

libpng decided it would be a good idea to warn everyone of "badly made" PNGs.
I think that warning is too strict, and can be safely ignored.
You can even downgrade libpng to get rid of the warning as well.

IIRC, all the png files that we used were made with gimp, and some of them crushed to save a few K.
Fixing the pngs via running them through imagemagik would work, but that is very, very annoying and causes huge issues doing bisects, so, I rather not "fix" them, and instead, they should squelch the warning, and only enable it with the --png-check flag @ compile time.

Super busy, don't expect a timely reply back.

Some of the images use alpha and in the past there has been issues with alpha its been know that gimp handles these issues, I'm not sure about imagemagik so to be sure if any png are to be fixed I advise using gimp
