Constructs an ImageProducer object which uses an array of integers in the default RGB ColorModel to produce data for an Image object.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {

    int[] pixels = new int[16 * 16];
    Image image = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, pixels, 0, 16));
    Cursor transparentCursor = Toolkit.getDefaultToolkit().createCustomCursor(image, new Point(0, 0),
            "invisibleCursor");
}
