Exception in thread "AWT-EventQueue-0" java.awt.IllegalComponentStateException: The frame is decorated

When trying to run the example I get the following:

ScreenCapturer: Width: 600 Height: 600 Proportion: 1.0

And the sketch does not work. Only a gray screen appears.

I have the same problem as well.
I want to fix the library tomorrow.

Any help with this problem? I have it too!
thanks

I looked into it but there where more things not done really well.

You can run this without needing the library:

SimpleScreenCapture simpleScreenCapture;

void setup() {
size(600, 400);
simpleScreenCapture = new SimpleScreenCapture();

}

void draw() {

image(simpleScreenCapture.get(), 0, 0, width, height);

}

---

import java.awt.Robot;
import java.awt.Rectangle;
import java.awt.AWTException;

class SimpleScreenCapture {

Robot robot;

PImage screenshot;

SimpleScreenCapture() {
try {
robot = new Robot();
}
catch (AWTException e) {
println(e);
}
}

PImage get() {
screenshot = new PImage(robot.createScreenCapture(new Rectangle(0, 0, width, height)));
return screenshot;
}

}

I can confirm this alternate method works. Can you suggest how to make the screen capture region moveable/sizeable? I'd really like those features.

[clankill3r]

That will be some more work. I suggest to look into the onformative/ScreenCapturer source code for that.
