PImage: loadImage not defined

Working on it

I'm using Eclipse with processing 1.2.1, and I can't seem to access PImage's loadImage method. I have imported the .jar successfully into the build path, and I have been able to run the other examples in the tutorials without a hitch.

Copy code

import processing.core.*;
public class Test {
void setup() {
PImage img = loadImage("test.jpg", "jpg");
}
}

On line 4, "loadImage" is underlined red. The error reads:

The method loadImage(String, String) is undefined for the type Test

I've also tried doing it other ways, e.g.:

Copy code

PImage img; //also tried PImage img = new PImage();
img = loadImage("test.jpg", "jpg");

I also tried these without the second parameter (which should not make a difference anyway if I read the documentation correctly). Same result with anything I try... It just doesn't seem to resolve PImage's loadImage method.

I just noticed that the documentation specifies to use createImage() instead of new PImage(). I tried the following:

Copy code

...
PImage img = createImage(604, 453, "RGB");
...

But I got the error:

The method createImage(int, int, String) is undefined for the type Test

It seems almost as if it's not even resolving the PImage class at all... It is, however, because I don't receive any error when declaring the PImage object (I would expect "PImage cannot be resolved to a type" if that were the case).

Well, I feel dumb. Forgot to do this when I started writing the class:

Copy code

public class Test extends PApplet {

I also needed a visibility for the setup function, and some other obvious stuff.
