[Insight-users] LabelObject OCR with numbers

[Christian Werner]

  Thanks for the response, but the CentroidX already changes with the 
position of the number. So if I am analyzing a sequence of numbers 
"146998" the CentroidX will be different than in the sequence "6138549".

This is really funny, who is responsible for that? Why use 9 symbols to 
represent 10 digits? :)
