Infinite loop saving a file in Processing

I made a method that saves a PImage into a file (.png, .jpg, etc...), but if the file exceeds a certain size [not size on disk, I mean the dimensions], the program will repeat over and over again.

I post the method and a lighter version of the sketch.

Sketch:

void setup(){
  noLoop();
  size(300, 300);
}

void draw(){
  background(0);
  text("Hello world!", 15, 15);
  PImage toEdit = loadImage("C:\\Users\\ingrossod\\Desktop\\toEdit.png");
  PImage toSave = change(toEdit, color(86, 177, 222), color(239, 254, 255));
  save(toSave, "C:\\Users\\ingrossod\\Desktop\\edited"); // The file extension is missing
}

Now, PImage change(PImage, color, color) takes a PImage and substitutes a color with another.

Here is void save(PImage, String):

void save(PImage toSave, String fileName){
  fileName += ".png"; // Adding the extension

  // Saving the current frame
  int oldWidth = width;
  int oldHeight = height;
  saveFrame(fileName);
  PImage oldFrame = loadImage(fileName);

  // Modifyng the current frame with the image I want to save
  size(toSave.width, toSave.height);
  background(toSave);
  saveFrame(fileName);

  // Restoring the frame with old parameters
  size(oldWidth, oldHeight);
  background(oldFrame);
}

I already tried modifying frameRate value, putting everything in one method calling it... Nothing.

The program WORKS with small images. Any idea on how to solve it?

Are you sure that infinite loop is not from change function? You do not provide us with its implementation.

My advice:

  1. use image(toSave, 0, 0) instead of background()
  2. use save(fileName) instead of saveFrame()

You've put noLoop in void setup, which prevents void draw continuing after frame 1. So frameRate is going to have precisely no effect..
