title: Algorithm to make halftone images?
body: <p>What is a good algorithm to make halftone images (like <a href="http://www.ransen.com/Repligator/Newsprint.htm" rel="noreferrer">this</a>)? A quick google search brings up a bunch of papers on the subject, but it's difficult to judge which are good, efficient, etc. Is there a best choice to do this sort of thing?</p>
