Noninteractive labeling of area

I am seeking a method to noninteractively label the
area inside a rectangle. I want to apply the rectangle
as a mask later. I would appreciate any suggestions.

Thank you.

I faced a similar problem a few months ago. In my case I was
fortunate enough to know the location of one internal point

following to create an attribute file:

From a file that looked like this:
118:16:11W 34:16:20N 101100
118:17:08W 34:15:04N 101200
