[PLUG-TALK] Copier enlargement scaling hack

When I use a copier to enlarge something, I often end up wasting
some pages determining the right enlargement factor.  So I wrote
a little postscript hack that prints out a series of nested boxes
with scaling factors on them, from 110% to 200%.  I use my HP4
postscript laser printer to print these out on overhead projector
transparency plastic (remember those?).  "lpr scaler.ps"

Now, whenever I want to enlarge a book page, or an illustration
from part of a page, or whatever, I can overlay the rectangles
over the book page and estimate the enlargement factor from the
best fit of the unenlarged image to one of the rectangles.  A
handy little tool to keep near the copier.

Here's the postscript:   http://kl-ic.com/scaler.ps
