Hi, i appreciate all the answers and thank you Komatös for the vectorized version (Please let me know how you did this!).
With an already vectorized Image I know now how to do this from v-kyr.
But actually PC-R is right, after the flood tool, I still have a bitmap with no background then. No separate objects, no outline.
Komatös helped me with this image, but I need to know how to do this for the future so I can do it myself.
You know, it's about this "teach them how to fish" thing 🙂
Thank you.
P.S.: Don't mind about the open objects like the Dolphins etc., I think I know how to handle that.
