[at-l] Math Help Needed

[bullard@northnet.org (James Bullard)]

The resolution (as in DPI) won't change but the scale will.  Scale is the 
number of actual feet/meters on the ground per inch/cm on paper.  When the 
image on paper gets bigger the scale changes. of course the reference scale 
drawn in the margin will be useless but you can always use a ruler.
