      Description

      Using the latest 2.1 I try to run this snipped to write a BufferedImage as a tif

      public void myTest() throws IOException {
              BufferedImage img = new BufferedImage(50, 50, BufferedImage.TYPE_INT_RGB);
              Graphics2D g2d = img.createGraphics();
              g2d.setBackground(Color.WHITE);
              g2d.fillRect(0, 0, 50, 50);
              g2d.setColor(new Color(20, 23, 54));
              BasicStroke bs = new BasicStroke(2);
              g2d.setStroke(bs);
              g2d.drawLine(0, 0, 25, 25);
              g2d.drawLine(10, 10, 5, 5);
              g2d.dispose();
              TIFFImageWriter writer = new TIFFImageWriter();
              writer.writeImage(img, new ByteArrayOutputStream(), null);
          }
      

      but I get the following

      java.lang.RuntimeException: Int or float buffers require 32-bit data.

      	at org.apache.xmlgraphics.image.writer.internal.TIFFImageWriter.writeImage(TIFFImageWriter.java:55)
      

      The same code works using TwelveMonkeys
