I would like to encode a png into adam7 algorithm.

https://en.wikipedia.org/wiki/Adam7_algorithm

I can't find anywhere how to do this...

Maybe someone here can help?

OFF TOPIC: I suggest every poll from now on to have "**CK EA" option instead of "Other"

You will need to read a PNG, check it's interlace with png_get_ihdr, then use png_set_ihdr to change the PNG interlace type, then save the png.

 

You can find the steps to do that looking in their manual:

I don't follow.

Is there a way to do this through linux command line, and not through C as it suggests?

is C the only way?

I have libpng installed... 

libpng-config --version
1.6.28

This is the output of running libpng-config --version
