What can it do?

Are words "clickable"?

Yes. Save a reference to the wordcram, and in your sketch's mouseClicked events, ask the wordcram whether there's a word at the mouse-click's coordinates. Something like this:

WordCram wordCram;

void setup() {
  wordCram = new WordCram(this)...
  wordCram.drawAll();
}

void mouseClicked() {
  Word word = wordCram.getWordAt(mouseX, mouseY);
  if (word != null) {
    ...
  }
}

For a complete running sketch like this, check out Sketchbook > libraries > WordCram > tutorials > L_clickableWords.

Can it write to PDF?

Yes! It was added in the 0.5 release.

Does it work with Processing.js?

No, but I'm looking into it. It depends on whether javascript can "sense" the shape of the words to detect collisions. But it would be really cool to see word clouds in the browser.

Something's not working right

Why do my words come out fuzzy?

If you're loading your fonts with loadFont, try using createFont instead. loadFont doesn't work as well for rendering characters at different sizes.

Why don't any of my words show up?

Are you using something like Colorers.pickFrom(0) or Colorers.pickFrom(255)? Try using Colorers.pickFrom(color(0)) and Colorers.pickFrom(color(255)) instead.

Processing internally stores colors as integers, with the alpha in the highest bits, so it sees the integer 0 as colorless and completely transparent. A WordCram created with Colorers.pickFrom(0) will render the words, they'll just be invisible.

Colorers.pickFrom() takes a bunch of colors, so it treats each integer it gets as a Processing color/integer. This is really a misleading API, and it should be sorted out.
