How can I write EXIF data to a TIFF image using Apache Commons Imaging?
This is what I tried:
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);
}
but I got this error:
Exception in thread "main" org.apache.commons.imaging.ImageReadException: Not a Valid JPEG File: doesn't begin with 0xffd8

which seems to indicate that the ExifRewriter
class does not support TIFF? But then which class should I use?

This also may be helpful
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);

ExifRewriter is a tool of the org.apache.commons.imaging.formats.jpeg
package, thus it does not work for the TIFF format.
In order to write the EXIF and tags to a TIFF file, you have to read it and then re-write it with the tags created for your OutputSet:
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);
}
You might then want to overwrite the original file with the exif-ed one:
Files.delete(Paths.get(f.toURI()));
Files.move(Paths.get(ex.toURI()), Paths.get(f.toURI()));
