So if I do this in ImageMagick on a commerical project:

  convert $infile \( $infile -blur 0x$width \) -compose minus +swap \ -composite -normalize $tmp0
  composite -blend $mix%x100% $tmp0 $infile -matte $outfile
I now owe Fred something?

So everyone that ever figures out how to do something neat with a free tool and documents it gets to claim the rights to that and ask for money?

Might not even be against this as an idea, but the premise seems shaky to me, I guess

Maybe more to the point is- if you want to ask for money for doing work like this, don't publish the ImageMagick command equivalents? Though I guess that would be hard to avoid other than putting it in some proprietary UI/app or something. Oh well.



No, if you save time reading imagemagick documentation by grabbing an off-the-shelf script, you owe him something


It's on the honor, ethics system. If you did the work, no worries.
