Emerson DeltaV (v14) Operate Configure Picture Layout

Hello all!

I am new to Emerson DeltaV. I am currently working on developing Graphic Pictures with Emerson DeltaV Operate Configure. My screen resolution is "1680x1050".

I have developed Pictures from the template "Main1680". I am facing a few issues understanding and configuring viewports, document size, and window size. It is all very confusing for me. I have worked on other systems where you can adjust your windows by simply using your resolution. For example. if you have  1920x1080 resolution on WinCC. I would normally have a top navigation bar of 200 Height and then I would subtract that from 1080 and have the remaining height 880 as my working window height with a width of 1920.

I was working on a picture and accidentally clicked "Fit Window to Picture" or "Fit Picture to Window" and now when i am in DeltaV Operate Run the picture is moving out of the viewport or has zoom issue.
