There are times when you must hide information from a document without changing its appearance and layout. I’m not talking about plain censorship, I meant like when you have to submit a paper to a journal or a conference anonymously while required to follow stringent layout guidelines. It may suffice to set a background of the same colors as the text, but if it does the thing in print, it doesn’t work so well with PDF where you can still select the text (and I did a blog entry using this behavior a while ago).
There’s a censor package for but it doesn’t play well with whole paragraphs, and it messes out the layout if you select more than just a word or two. This week’s entry proposes a simple macro to do nice (but not weapon-grade) “censoring”.
