Image Sampler on Spiral Lines

Grasshopper
#1

Hi,

I am trying to make a pattern for CNC cutting using image sampler on spiral lines.
From a test that I made, it looks like the value for the image is not correct with the value for the point. See image below:

I have searched for this topic, but couldn’t find it.
Attached is the gh file.

I would really appreciate your help!

Cheers!

Hi,
Image sampler expects points with X and Y coordinates between 0.0 and 1.0. You could change it inside image sampler but I usual keep it default.

Instead of fixing your code I’ve made my own example:
