Garret Wilson created IMAGING-281:
-------------------------------------
Summary: Simple Exif XPTitle corrupted.
Key: IMAGING-281
URL: https://issues.apache.org/jira/browse/IMAGING-281
Project: Commons Imaging
Issue Type: Bug
Affects Versions: 1.0-alpha2
Reporter: Garret Wilson
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 that cannot be read in
ExifTool is a show-stopper.)
I'm will attach the test case image to this ticket.
