------------------------------------

the first field in a IFD is a String
Key: IMAGING-319
URL: https://issues.apache.org/jira/browse/IMAGING-319
Project: Commons Imaging
Issue Type: Bug
Components: Format: JPEG
Affects Versions: 1.0-alpha2
Reporter: Sicheng Yang

I try to use TiffOutputSet to generate a new image. However, if a tag that
contains String, the program may miss the first character of the String.
import java.io.*;
import org.apache.commons.imaging.ImageReadException;
import org.apache.commons.imaging.ImageWriteException;
import org.apache.commons.imaging.Imaging;
import org.apache.commons.imaging.common.ImageMetadata;

import org.apache.commons.imaging.formats.tiff.TiffImageMetadata;
import org.apache.commons.imaging.formats.tiff.write.TiffOutputSet;
public class LibraryTest {
public static void main(String[] args) throws ImageReadException,
IOException, ImageWriteException {
File source = new File("./assets/iPhone12-geotag.JPG");
File result = new File("./assets/results/editted-iPhone12-geotag.JPG");
final ImageMetadata metadata = Imaging.getMetadata(source);
final JpegImageMetadata jpegMetadata = (JpegImageMetadata) metadata;
final TiffImageMetadata exif = jpegMetadata.getExif();
TiffOutputSet outputSet = exif.getOutputSet();
BufferedOutputStream bufferedOutputStream = new
BufferedOutputStream(new FileOutputStream(result));
new ExifRewriter().updateExifMetadataLossless(source,
bufferedOutputStream, outputSet);
}
}
This is the sample code.
Tag value in original image
