Scale size of pictures

    int rgb[];
    int rescaledRGB[];

    // Current width and height values
    width = image.getWidth();
    height = image.getHeight();

    // Get the RGB values for each pixel in the image
    rgb = new int[ width * height ];
    image.getRGB( rgb, 0, width, 0, 0, width, height );

    // Create a new rescaled image
    rescaledRGB = reescaleArray( rgb, width, height, newWidth, newHeight );
    image = Image.createRGBImage( rescaledRGB, newWidth, newHeight, true );
  }

I use the code in the paint method of my splash screen:

      Picture logo = new Picture();
      logo.setImage("/logo.png");
      logo.rescaleToWidth(g.getClipWidth() -
UIManager.getTheme().getVerticalScrollbarWidth() - 1);
