Hello all,
I am new to processing and I'd like a hint regarding a problem. I am drawing an image on the canvas(let's say at point (100,200)). This is the upper-left origin of my image on the canvas. From this I can deduce the lower-left, upper-right and lower-right coordinates based on the width and height of my image. All fine till there although I would expect there to be a method to give me these values directly. The real problem occurs when I rotate my image on the canvas. After applying a rotation to the image I can no longer deduce my x/y coordinates by simply adding the width and height of the image to my root coordinates. What I want to know is whether there is an easy way of getting the x/y coordinates of the image on all corners directly or do I have to apply a transformation matrix myself to my original coordinate matrix of the image to get these new values?

In other words is there anyway to know the image.topleft, image.topright, image.lowerleft, image.lowerright coordinates directly or do I have to always deduce these myself according to the transformations I apply on the image?
