- Then, iterate through the EXIF tags on different levels.
- Lastly, conclude the process.
Sample Code to View EXIF Data with C#
using (Metadata metadata = new Metadata(Constants.JpegWithExif)) | |
{ | |
IExif root = metadata.GetRootPackage() as IExif; | |
if (root != null && root.ExifPackage != null) | |
{ | |
const string pattern = "{0} = {1}"; | |
foreach (TiffTag tag in root.ExifPackage.ToList()) | |
{ | |
Console.WriteLine(pattern, tag.TagID, tag.Value); | |
} | |
foreach (TiffTag tag in root.ExifPackage.ExifIfdPackage.ToList()) | |
{ | |
Console.WriteLine(pattern, tag.TagID, tag.Value); | |
} | |
foreach (TiffTag tag in root.ExifPackage.GpsPackage.ToList()) | |
{ | |
Console.WriteLine(pattern, tag.TagID, tag.Value); | |
} | |
} | |

Installing Java EXIF Data Viewing Library
To install the Java EXIF data viewing library, add the Conholdate.Total for Java library as a dependency in your project using Maven or Gradle. You can find installation instructions and the library here: Releases of Conholdate.Total for Java
Steps to View EXIF Metadata using Java
- First, load an EXIF metadata-containing file.
- Second, use the IExif.getExifPackage method, to extract the EXIF metadata package.
- Finally, Iterate over the EXIF tags at various levels.
Sample Code to Read EXIF Data using Java
try (Metadata metadata = new Metadata(Constants.TiffWithExif)) { | |
IExif root = (IExif) metadata.getRootPackage(); | |
if (root.getExifPackage() != null) { | |
System.out.println(root.getExifPackage().getArtist()); | |
System.out.println(root.getExifPackage().getCopyright()); | |
System.out.println(root.getExifPackage().getImageDescription()); | |
System.out.println(root.getExifPackage().getMake()); | |
System.out.println(root.getExifPackage().getModel()); | |
System.out.println(root.getExifPackage().getSoftware()); | |
System.out.println(root.getExifPackage().getImageWidth()); | |
System.out.println(root.getExifPackage().getImageLength()); | |
// ... | |
System.out.println(root.getExifPackage().getExifIfdPackage().getBodySerialNumber()); | |
System.out.println(root.getExifPackage().getExifIfdPackage().getCameraOwnerName()); | |
System.out.println(root.getExifPackage().getExifIfdPackage().getUserComment()); | |
// ... | |
System.out.println(root.getExifPackage().getGpsPackage().getAltitude()); | |
