Constructor Details

#initialize(options = {}) ⇒ App

Since processing-3.0 you should prefer setting the sketch width and height and renderer using the size method in the settings loop of the sketch (as with vanilla processing) but is hidden see created java. Options are no longer relevant, define post_initialize method to use custom options (see Sandi Metz POODR)
