The docs show a way of injecting chunks into the output PNG file:

https://www.imagemagick.org/script/comm ... ns.php#set

the syntax is

convert in.png -set profile PNG-chunk-b:<filename> out.png

, but this doesn't appear to work (I've tried on OSX and Ubuntu)

Anyone know what I might be doing wrong here?

I don't know the answer, but for those who might:

- What version IM are you using?

- You might supply the exact command you have tried, with the chunk file you used.
