Cool collection of effects. Too bad they are free for non-commercial use only.
To put it bluntly: pay the dude for the effort.
He shows the equivalent IM command lines, and it's 2 lines of text.
No issue with the more complex ones though...it's his work.
convert $infile \( $infile -blur 0x$width \) -compose minus +swap \ -composite -normalize $tmp0
composite -blend $mix%x100% $tmp0 $infile -matte $outfile
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.
