Garret Wilson updated IMAGING-281: ---------------------------------- Description: I have a small input JPEG image containing _no metadata sections whatsoever_. I use Apache Commons Imaging 1.0-alpha2 to add two simple Exif {{IFD0}} properties using [{{ExifRewriter().updateExifMetadataLossy()}}|https://commons.apache.org/proper/commons-imaging/apidocs/org/apache/commons/imaging/formats/jpeg/exif/ExifRewriter.html#updateExifMetadataLossy-org.apache.commons.imaging.common.bytesource.ByteSource-java.io.OutputStream-org.apache.commons.imaging.formats.tiff.write.TiffOutputSet-]. * {{XPTitle}} ({{0x9C9B}}): "Gate and Turret" * {{Copyright}} ({{33432}}, {{0x8298}}): "Copyright © 2009 Garret Wilson" Here is a simplified excerpt of the code: {code:java} TagInfoAscii EXIF_XP_TITLE_TAG_INFO = new TagInfoAscii("XPTitle", 0x9C9B, -1, TiffDirectoryType.EXIF_DIRECTORY_IFD0); //XPTitle (0x9C9B) TagInfoAscii EXIF_COPYRIGHT_TAG_INFO = new TagInfoAscii("Copyright", 0x8298, -1, TiffDirectoryType.EXIF_DIRECTORY_IFD0); //Copyright (33432, 0x8298) … TiffOutputSet tiffOutputSet = new TiffOutputSet(); TiffOutputDirectory exifDirectory = tiffOutputSet.getOrCreateRootDirectory(); exifDirectory.add(EXIF_XP_TITLE_TAG_INFO, "Gate and Turret"); exifDirectory.add(EXIF_COPYRIGHT_TAG_INFO, "Copyright © 2009 Garret Wilson"); … new ExifRewriter().updateExifMetadataLossy(byteSource, outputStream, tiffOutputSet); {code} Using [ExifTool|https://exiftool.org/] 12.16 (via [ExifToolGUI|https://exiftool.org/gui/) 5.16.0.0], the {{Copyright}} value is stored correctly but the {{XPTitle}} is stored as "慇整愠摮吠牵敲t". [Metadata++|https://www.logipole.com/metadata++-en.htm] 1.22.14 also shows the same corrupted value. This is disheartening, as this is nearly the most simple test case possible. (Note that [IrfanView|https://www.irfanview.com/] 4.54 can read the {{XPTitle}} just fine! Nevertheless ExifTool is the gold standard for image metadata reading, and is confirmed by Metadata++. Having an image the metadata of which cannot be read in ExifTool is a show-stopper.) I'm will attach the test case image to this ticket. was: I have a small input JPEG image containing _no metadata sections whatsoever_.
