Body: <p>I'm trying to write a program for my Lego Mindstorm NXT, the program is simple, drawing some lines and saving the image in a .png file. So, I thought I'd use BufferedImage and use getGraphics to draw on it, the thing is; if I write the code:</p>
  
  <pre><code>import java.awt.image.BufferedImage;
  
  import lejos.nxt.Button;
  
  public class Main {
  
      public static void main(String[] args) {
          System.out.println("Test\n");
          BufferedImage bimg = new BufferedImage(300,300, BufferedImage.TYPE_3BYTE_BGR);
          Button.waitForAnyPress();
  
      }
  }
  </code></pre>
  
  <p>When I run the program, it freezes for a while in "Linking..." and gives me the following:</p>
  
  <pre><code>Java Heap Space
  Java.Lang.OutOfMemory
  </code></pre>
  
  <p>So the question is this: How can I use BufferedImage with Lejos without having this problem? And if there's another method of drawing lines and saving the image on a file, it would be very helpful.</p>
  
  <p><strong>EDIT:</strong>
  The Java Heap Space is caused by the line </p>
  
  <pre><code>BufferedImage bimg = new BufferedImage(300,300, BufferedImage.TYPE_3BYTE_BGR);
  </code></pre>
  
  <p>I've also tried using ImageIO:</p>
  
  <pre><code>import javax.microedition.lcdui.Image;
  *
  *
  Image img = Image.createImage(300, 300);
  ImageIO.write((RenderedImage) img, "png", monFichier);
  </code></pre>
  
  <p>It gives me the same thing. I don't know but maybe this isn't the right way to create an image with Lejos. What do you think?</p>

  Thank the Java Heap Space comes up. I've edited the question.

          Button.waitForAnyPress();
  
      }
  }
  
  When I run the program, it freezes for a while in "Linking..." and gives me the following:
  Java Heap Space

  So the question is this: How can I use BufferedImage with Lejos without having this problem? And if there's another method of drawing lines and saving the image on a file, it would be very helpful.
  EDIT:
