Finding faulty PNGs

[Wuzzy]

I often have the problem that faulty PNGs sneak into my game files, triggering libpng warnings. However, I have a lot of PNG and I know some of them are faulty (usually incorrect sRGB profile). But I don't know which of my lots and lots of PNGs are faulty.

Here's my question to you:
Given a large directory containing many PNGs of which a few are faulty, how do I locate the faulty PNGs?

Did a quick STFW and found this: https://www.davidebarranca.com/2018/05/ ... agemagick/

Could be as simple as this

{l Code}: {l Select All Code}

#!/bin/bash

shopt -s nullglob
for file in ./*.png; do
   identify "$file" > /dev/null 2>&1
   if [ "$?" -ne "0" ]; then
      echo "File $file is corrupt."
   fi
done

Ah, thanks. I didn't know that the identify program gives an useful return code for faulty PNGs. That's nice.

ImageMagick is pretty daunting, to be honest, there's so much you must read. xD But it's also pretty awesome.

Yeah almost always enough to read :-P IBut 've made a mistake, you might want to add the `-regard-warnings` flag to the identify command for it to be more strict.
