Template layout displaying not matching the image X/Y ratio

When template is detected, its layout is displayed on black (I suggested to have it in green, contrast is better).

I have noticed that when I carefully try and overlay the layout over the image, this never matches.

That is because the X/Y ratio of the layout is not the same than displayed picture.

The wrong one is actually displayed picture's. I carefully measured it orthogonally placing the TC55 on top of it.

Viewfinder's image is not proportioned, while layout seems to be (that one is impossible to measure ).


I also found that DPXDemo's viewfinder shows exactly what camera does (both are distorted).

Yet, once one takes the photo, resulting image is NOT (pls find attached).


Could this be a problem when identifying the fields -harder to detect?
