Scanning and Image Corrections Lab

SO503 Spring 2007

You are writing a review paper for the Journal of Irreproducible Results.  You want to include a figure that appeared in EOS , vol.82, no.11, p.136, and have secured permission from the American Geophysical Union to use it.

You are armed with tools on your PC: Paint and perhaps Windows Imaging.  While better tools exist, you are assured of finding Paint on any Windows PC.

Your assistant has scanned the figure 11 times so you can pick the best one.  The file names indicate the color choice and scanning resolution in dpi.

·               How does file size increase as the color resolution increases?

·               How does file size increase as the scanning resolution increases?

·               Which color choice is "best"?  Why?

·               Which resolution is "best"?  Why?

·               Can you change the color scheme after the picture is scanned?  How well does this work?

Pick the best scan for submission.

What difference does it make when you select "Draw opaque" on the options menu?  (The correct choice here will make other operations easier.)

What is the utility of the View Zoom menu choice?

The editor at the Journal has noticed that the units on the x axis of  the graph are incorrect.  You must correct them.  She also wants a capital M on "median".

After fixing the label on the horizontal axis, the editor complains that the vertical axis uses a different font than the horizontal axis.  Correct that problem.

The editor wants the numbers on the axes to be larger, and the subscripts placed higher.  Correct those.

Can you get rid of the mark from the crease in EOS?

If the scan is not straight, how can you correct that in Paint?
