New Post: Working with clipping paths

Here is an example file, containing a clipping path: https://1drv.ms/u/s!ArI0AGq7GprKiJU_nxbercKV1mQ_Cw

I don't really get your example. I guess this part

image.Alpha(AlphaOption.Transparent);
image.Clip("Pfad 1", true);
image.Alpha(AlphaOption.Opaque);

should remove the background?
For changing the background Color I was assuming I can use the "FloodFill"-Option, after using Clip(), but this isn't working either.
