Using the chrome extension, Screen Capture (by Google) 5.0.3, I did a
"Capture Visible Content" and saved the png (as-is) to this
directory as "saved.png".  Then with imagemagick:

  convert saved.png -background white -flatten -alpha off \
               -resize 350x200\! SERVLETNAME.png
  rm saved.png	       

where SERVLETNAME is the name of the servlet class as found in
TutorialBase.TutorialBase.tutorials.
