Can i get a pixel color value without converting the picture data to an array?
Seems an unneccesary step in my opinion because internally the array data is available
anyway.
Neither the standard palette nor the vi.lib picture vis seems to contain procedures to read pixel values.

I think the answer is "no". And I think the reason the answer is "no" is "representation". I suspect that images work by passing around references ("pointers") to data, and when you want to get at the data, you need to "get the data" by asking LabVIEW to give you the Pixel array.

If you are using MS Windows, and the image is displaying on a front panel, there is a Windows API: GetPixel (https://msdn.microsoft.com/en-us/library/dd144909(v=vs.85).aspx) for that.
