This Gizmo lets you see on screen the RGB and Luminance (Y) values of a sampled area (Sample Width, Sample Height) May not work on LINUX (some font access issues) Will post again when I find a way (if there is one) to make it work on both windows and linux

This Gizmo lets you see on screen the RGB and Luminance (Y) values of a sampled area (Sample Width, Sample Height)
You just have to specify the image input FORMAT. You can also have access to the RGBY data if you want to link them to any other tool.
The only limitation for now is that the sampling box can't be over 50x50 pixels. I am using the 'sample' function. It should be able to sample any region, but strangely if you put higher values for the sampling width and height, the result values don't change
I've written to The Foundry to find out if it's a bug or if I'm doing something wrong. Still waiting for an answer.
If I can fix this limitation, I'll upload an upgraded version.
This gizmo is a partial replica of Gregory Chalenko's macro in Fusion 'Color Sampler'
