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.

The same code works using TwelveMonkeys
