I want to simply adapt the display window size to the image I load. I read that with processing3 it is not possible anymore to use variables for defining size and that it is necessary to use settings.  
I tried but it does not work.  
This is what I’m doing right now

```auto
PImage img;

void settings() {
  img = loadImage("image.jpg");  
  size( img.width, img.height);
}

void setup() {
image(image, 0, 0);
}

```

this is all a bit of a mess still.

this does work

```auto
PImage img;

void settings() {
  size(0,0, P2D);
}

void setup() {
  img = loadImage("image.jpg");
  surface.setSize(img.width, img.height);
}

void draw() {
  image(img, 0, 0);
}

```

but what’s weird is if you don’t use the draw function and keep your original version with the other adjustments it doesn’t. lol.

```auto
PImage img;

void settings() {
  size(0,0, P2D);
}

void setup() {
  img = loadImage("frodo.jpg");
  surface.setSize(img.width, img.height);
  image(img, 0, 0);
}

```

you basically end up with the correct window size but the image doesn’t display correctly. so yeh use the first version i posted. unless someone else has a way to do this? gotoloop? chrisr?
