Directory.containsTag介绍

[英]Indicates whether the specified tag type has been set.
[中]指示是否已设置指定的标记类型。

代码示例

代码示例来源：origin: drewnoakes/metadata-extractor

public boolean hasFollowerIfd()
{
  // In Exif, the only known 'follower' IFD is the thumbnail one, however this may not be the case.
  // UPDATE: In multipage TIFFs, the 'follower' IFD points to the next image in the set
  if (_currentDirectory instanceof ExifIFD0Directory || _currentDirectory instanceof ExifImageDirectory) {
    // If the PageNumber tag is defined, assume this is a multipage TIFF or similar
    // TODO: Find better ways to know which follower Directory should be used
    if (_currentDirectory.containsTag(ExifDirectoryBase.TAG_PAGE_NUMBER))
      pushDirectory(ExifImageDirectory.class);
    else
      pushDirectory(ExifThumbnailDirectory.class);
    return true;
  }
  // The Canon EOS 7D (CR2) has three chained/following thumbnail IFDs
  if (_currentDirectory instanceof ExifThumbnailDirectory)
    return true;
  // This should not happen, as Exif doesn't use follower IFDs apart from that above.
  // NOTE have seen the CanonMakernoteDirectory IFD have a follower pointer, but it points to invalid data.
  return false;
