如何使用 Apache Commons Imaging 将 EXIF 数据写入 TIFF 图像？

这是我尝试过的：

File img = new File("pic.tif");
File dst = new File("out.tif");
try (FileOutputStream fos = new FileOutputStream(dst);
     OutputStream os = new BufferedOutputStream(fos)) {

    TiffOutputSet outputSet = null;

    final ImageMetadata metadata = Imaging.getMetadata(img);
    final TiffImageMetadata tiffMetadata = (TiffImageMetadata) metadata;
    outputSet = tiffMetadata.getOutputSet();

    if (null == outputSet) {
        outputSet = new TiffOutputSet();
    }

    // New York City
    final double longitude = -74.0;
    final double latitude = 40 + 43 / 60.0;
    outputSet.setGPSInDegrees(longitude, latitude);

    new ExifRewriter().updateExifMetadataLossless(img, os, outputSet);
}

但我收到了这个错误：

Exception in thread "main" org.apache.commons.imaging.ImageReadException: Not a Valid JPEG File: doesn't begin with 0xffd8

这似乎表明ExifRewriter该类不支持 TIFF？但是我应该使用哪个类？

ExifRewriter 是该org.apache.commons.imaging.formats.jpeg软件包的一个工具，因此它不适用于 TIFF 格式。

为了将 EXIF 和标签写入 TIFF 文件，您必须读取它，然后使用为您的 OutputSet 创建的标签重新写入它：

BufferedImage img = Imaging.getBufferedImage(f);
byte[] imageBytes = Imaging.writeImageToBytes(img, ImageFormats.TIFF, new HashMap<>());

File ex = new File(FileUtils.getBaseFileName(f) + "_exif." + FileUtils.getExtension(f));
try(FileOutputStream fos = new FileOutputStream(ex);
    OutputStream os = new BufferedOutputStream(fos)) {
    new TiffImageWriterLossless(imageBytes).write(os, outputSet);
}

然后，您可能想用 exif-ed 覆盖原始文件：

Files.delete(Paths.get(f.toURI()));
Files.move(Paths.get(ex.toURI()), Paths.get(f.toURI()));

这也可能有帮助

            BufferedImage bufferedImage = Imaging.getBufferedImage(out.toByteArray()); 
            File imageFile = new File(outputFileName);
            final Map<String, Object> optionalParams = new HashMap<String, Object>();

            TiffOutputSet tiffExif = new TiffOutputSet();
            tiffExif.addRootDirectory().add(MicrosoftTagConstants.EXIF_TAG_XPTITLE, "Title");
            optionalParams.put("EXIF", tiffExif);
            Imaging.writeImage(bufferedImage, imageFile, ImageFormats.TIFF, optionalParams);
