GroupDocs.Metadata for Java makes it easy for Java developers to edit metadata details to Heic files from within their applications by implementing a few easy steps.
// Edit HEIC creation date metadata
public class UpdatingMetadata
{
public static void run()
{
Date threeDaysAgo = new Date(System.currentTimeMillis() - TimeUnit.DAYS.toMillis(3));
try (Metadata metadata = new Metadata("input.heic"))
{
// Update the file creation date/time if the existing value is older than 3 days
int affected = metadata.updateProperties(new ContainsTagSpecification(Tags.getTime().getCreated()).and(
new OfTypeSpecification(MetadataPropertyType.DateTime)).and(
new UpdatingMetadata().new DateBeforeSpecification(threeDaysAgo)), new PropertyValue(new Date()));
// Process updation result
System.out.println(String.format("Affected properties: %s", affected));
// Save edited file
metadata.save("output.heic");
}
}
// Define your own specifications to filter metadata properties
public class DateBeforeSpecification extends Specification
{
public DateBeforeSpecification(Date date)
{
setValue(date);
}
public final Date getValue()
{
return auto_Value;
}
private void setValue(Date value)
{
auto_Value = value;
}
private Date auto_Value;
public boolean isSatisfiedBy(MetadataProperty candidate)
{
Date date = candidate.getValue().toClass(Date.class);
if (date != null)
{
return date.before(getValue());
}
return false;
}
}
}

GroupDocs.Metadata simplifies adding different metadata to documents and files within your Java apps. Developers can effortlessly apply, update, or remove metadata.
The API offers extensive options for customizing metadata. It is easy to find metadata in files using special requests and remove or update them.
Depending on the document format, developers can leverage built-in metadata like EXIF for images. This might include information about photo like camera model and number, resolution, creation date and other.
// Load file to Metadata class constructor
try (Metadata metadata = new Metadata("input.mp3")) {
MP3RootPackage root = metadata.getRootPackageGeneric();
if (root.getLyrics3V2() == null) {
root.setLyrics3V2(new LyricsTag());
}
// Update lyrics data
root.getLyrics3V2().setLyrics("[00:01]Test lyrics");
root.getLyrics3V2().setArtist("test artist");
root.getLyrics3V2().setAlbum("test album");
root.getLyrics3V2().setTrack("test track");
// You can add a fully custom field to the tag
root.getLyrics3V2().set(new LyricsField("ABC", "custom value"));
// Save result
metadata.save("output.mp3");
}
