I tried to do subclass for PImage but it didn't really work out because of the way PImage's are constructed:

PImage img = loadImage("imageFile");

I want to have a subclass of PImage that inherits the qualities of PImage, but I don't know how to go about writing the constructor since it is irregular.

Has anyone done something like this before?

To successfully make polymorphism from methods of class PImage,

you have to study Processing's source code!

Also note that class PGraphics is already a child class of PImage!

Instead of sub-classing, you can use composition: having a PImage in a class.
Inheritance is out of fahsion these days, anyway...

(but I still use it, when I need it).
