Hi,
I need to produce a small application that can examine the contents of a board 
outline gerber file produced by PCBNEW.
The application needs to read the gerber file and extract the X and Y 
co-ordinates and spit out the actual board size.
Is it possible to extract a board size from the following Gerber file syntax 
for example?

Which lines describe the actual top-left,top-right, bottom-left and 
bottom-right X and Y co-ordinates. All I need to end up with is a set of 
numbers from which I can calculate the actual length and width of a PCB (in 
inches (MILS) or mm). Can someone point me in the right direction? I would be 
very grateful for any assistance offered.Thanks.



David.
