Hi all  
I have a NumPy array, representing an image, I send from a python module to a Julia function.  
The NumPy array is received in the Julia function as Array{UInt8, 3}. I need to convert it to Matrix{RGB{N0f8}}.  
How do I do that?  
Thank you all!  
Alon

I found this solution:

> Hey guys, I use the NumPy per PyCall to get screenshots of my desktop. I get these images back as 1440×3440×3 Array{UInt8, 3} Discord user borodi#9175 already shared a function of him that converts this array to a BGR. opencvtojulia(abc) = BGR.(reinterpret.(N0f8,abc[:,:,3]),reinterpret.(N0f8,abc[:,:,2]),reinterpret.(N0f8,abc[:,:,1])) Because it changes a lot of colors to the wrong ones i have to fix something in it. Has somebody an idea how to get RGB images from this function or what else …

Which solved my problem perfectly.
