如何在Java中爲TIFF文件創建縮略圖？

Question

有人可以幫助一些代碼創建一個TIFF在Java中的縮略圖。

使用此Post我創建了JPEG和PNG的縮略圖。

Answer 1

BufferedImage image = ImageIO.read(aFile); 
    BufferedImage thumbnNailImage = new BufferedImage(width, height, 
      BufferedImage.TYPE_INT_RGB); 

    Graphics2D g2 = thumbnNailImage.createGraphics(); 
    g2.fillRect(0, 0, width, height); 

    double xScale = (double) width/image.getWidth(); 
    double yScale = (double) height/image.getHeight(); 
    double scale = Math.min(xScale, yScale); 

    double x = (width - image.getWidth() * scale)/2; 
    double y = (height - image.getHeight() * scale)/2; 
    AffineTransform at = AffineTransform.getScaleInstance(x, y); 
    at.scale(scale, scale); 
    g2.drawRenderedImage(image, at); 
    g2.dispose(); 
    return thumbnNailImage; 

當讀取ImageIO.read（aFile）;總是返回null。
