如何在Java中为TIFF文件创建缩略图？

Question

有人可以帮助您使用一些代码来创建Java中的TIFF缩略图。

使用此Post我为JPEG和PNG创建了缩略图。

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;

阅读ImageIO.read（aFile）;总是返回null。
