Thanks for the updates Peter my friend! Lotsa kudos \o/
Sorry for not testing these faster (as I normally do) but my daughter recently born 2 weeks ago so I gave all my attention to her and my wifey
I just tried the last version and it works awesome as always! For some reason the test icons on your AllIconsOnWB archive seemed a lot faster (especially the PNG ones).
I also converted an icon via CopyIcon from OS4 format to classic format and from 17KB it reduced to 4.9KB and with a lot greater speed!
Congratz for at LAST getting out of shity copyright Amiga Inc stuff restrictions. I really hope other coders will have your success
