How to use settings() to resize the sketch to an image size

I need to use loadImage to get the image size and then pass the parameters to size. How to do this in PS3?

Thank you! So there is no way this would work?

PImage source;       // Imagem original
PImage destination;  // Imagem de destino
int algoritmo = Dither.FLOYD_STEINBERG; //Determina o algoritmo
Dither dither = new Dither(algoritmo); //Instancia o filtro
int tempoTexto = (4 * 30) + 255;
String texto = "";

void settings(){
  source = loadImage("trabalho.png");
  size(source.width, source.height);
}

GoToLoop

Inside settings() no way! Pay attention to the code examples from the link I've passed to ya! 3:-O

GoToLoop, thank you very much! It's working now, but this is not documented in the reference, right?

I'll just post the code here for future references:

PImage source;       // Imagem original
PImage destination;  // Imagem de destino
int algoritmo = Dither.FLOYD_STEINBERG; //Determina o algoritmo
Dither dither = new Dither(algoritmo); //Instancia o filtro
int tempoTexto = (4 * 30) + 255;
String texto = "";

void setup() {
  //Carrega a imagem original
  source = loadImage("trabalho.png");
  surface.setSize(source.width, source.height);

Anything involving variable surface and the old frame is undocumented! :-&
They had even protected surface's access level, dunno why! 8-}
In order to access surface's outside its class, we need its getSurface()'s "getter"! X(
