Inverse of an Image

[VeMo]

Hello,

I am trying to calculate/create inverse of an image but without using the available vi in the LabVIEW. Does someone have any idea how can I take an image and create its inverse using simple math functions and a loop? the image is 8 bit image so the values will be between 0 and 255. In this case inverse just will be 255 subtract each pixel value I think but I was not able to create something that is easy to look at and understand. I need some help. 

Thanks

Yes something similar, but I was able to make the program myself in the way I wanted. Thank you so much for your reply and offer to help.
