Binary conversion of a big image leads to "java.lang.OutOfMemoryError"?

Question

Hi,
My program loads a black and white 1 bit depth image of around 20 - 30mb. When I try to convert it to binary image, it gives the following error: java.lang.OutOfMemoryError: Java heap spaceI am converting a bufferedimage to binaryimage. I used the following conversion method:      
// This method converts an image to a binary image:
     public static BufferedImage convert (BufferedImage src, int type)
          int w = src.getWidth ();
          int h = src.getHeight ();
          BufferedImage dst = new BufferedImage (w, h, type);
        Graphics2D g = dst.createGraphics ();
        g.drawRenderedImage (src, null);
        g.dispose ();
          return dst;
     }The program was working well before but now it keeps giving the heap memory error which is really weird. Is there any way I can fix this? Can anybody suggest a better way to convert a black and white image to binary data. Thanks.

You could increase maximum memory (-Xmx): [http://java.sun.com/javase/6/docs/technotes/tools/windows/java.html]
