The ParagraphStyle object represents the paragraph style of a text item (textItem.paragraphStyle).
Currently, the ParagraphStyle object may seem a bit empty, with just the justification property. Yet, we have lots in store for Paper.js when it comes to typography. Please stay tuned.
var text = new PointText(new Point(0,0)); text.fillColor = 'black'; text.content = 'Hello world.'; text.paragraphStyle.justification = 'center';
