```
public class TikaAutoMetadataExtracter
extends TikaPoweredMetadataExtracter

  Because some editors use JPEG_IMAGE_HEIGHT_TAG when saving JPEG images , a more reliable source for image size are the values provided by Tika and not the exif/tiff metadata read from the file This will override the tiff:Image size which gets embedded into the alfresco node properties for jpeg files that contain such exif information
