yesterday David Rutten released a grasshopper with a scripting component...

great !!! That was what I was waiting for. To me now it is complete and includes everything that I could have asked for when I downloaded the first version.

Here an example of the scriting Component (VB) that came to my mind first as I was using RhPicture for Rhinoscript a lot these days.

Now Grasshopper can read images, too...

and here the logic to read out the pixels:

It uses the "getPixel" method of the Graphics Class from DotNET

Originally I wrote the code for a GC feature but in grasshopper its even less code...
