1) From SUN example

    private Image resize(Image image, int width, int height) {
        int sourceWidth = image.getWidth();
        int sourceHeight = image.getHeight();
                
        Image thumb = Image.createImage(width, height);
        Graphics g = thumb.getGraphics();
        
        for (int y = 0; y < height; y++) {
            for (int x = 0; x < width; x++) {
                g.setClip(x, y, 1, 1);
                int deltaX = x * sourceWidth / width;
                int deltaY = y * sourceHeight / height;
                g.drawImage(image, x - deltaX, y - deltaY, Graphics.LEFT | Graphics.TOP);
            }
        }
        
        Image immutableThumb = Image.createImage(thumb);
        
        return immutableThumb;
    }

2: From this forum

private int[] reescalaArray(int[] ini, int x, int y, int x2, int y2) {
   int out[] = new int[x2*y2];
   for (int yy = 0;  yy < y2; yy++) {
     int dy = yy * y / y2;
     for (int xx = 0; xx < x2; xx++) {
       int dx = xx * x / x2;
       out[(x2*yy)+xx]=ini[(x*dy)+dx];         }       }
   return out;}
 
private Image getSmall(Image temp, int newX, int newY) throws Exception{
   //Need an array (for RGB, with the size of original image)
   int tX = temp.getWidth();
   int tY = temp.getHeight();
   int  rgb[] = new int[tX*tY];//Get the RGB array of image into  "rgb"
    temp.getRGB(rgb,0,tX,0,0,tX,tY);//Call to our function and obtain RGB2
    int rgb2[] = reescalaArray(rgb,tX,tY,newX,newY);//Create an image with that RGB array
    rgb = null;
    Image temp2 = Image.createRGBImage(rgb2,newX,newY,true);
    rgb2 = null;
    return temp2;
