Dear Raul,

your definition shows me this.
Is that right? I have not worked for a long time with Grasshopper,
Would it be possible for you to make your answer a little more detail?

Thank you!

Dear Raul,

Thank you for your quick response!
For example, if I take this image of Barak Obama,
I would have with your definition following response?

What does this means?

"Floating parameter image failed to collect data"

And how to grouped different color values?

That means: the component has no image.

Also in my example you don't need the "Image Sampler" Component.

You have to right klick "F" and choose "Set one File Path". Then you must set the Path to your picture (like "C:\....bla.jpg")

Please let me know if it works.

Is it not possible to equip your definition with more horsepower? :D

I need more color value.

sorry but i have no other idea. The "IMG" and "DeMesh" components are the bottleneck.

Ugh! Its the C# component

Im a bit confused because i just fill a list...

private void RunScript(List<Color> C, ref object A)
{
    List<Color> myColorList = new List<Color>();

    foreach (var my_color in C)
    {
      if (!myColorList.Contains(my_color))
      {
        myColorList.Add(my_color);
      }
    }

    A = myColorList;
}
