[jira] [Commented] (TIKA-1670) Metadata.IMAGE_WIDTH and Metadata.IMAGE_LENGTH is not given for PNG files.

["Nick Burch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-1670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14608414#comment-14608414 ] 

Nick Burch commented on TIKA-1670:
----------------------------------

It's showing up for me with the Tika app:
{code}
$ java -jar tika-app-1.10-SNAPSHOT.jar --metadata festival-anak-bertanya-2015_o.png  | grep 'tiff:Image'
tiff:ImageLength: 844
tiff:ImageWidth: 600
{code}

Do you get any metadata for the file? Have you ensured that you've really got the Tika Parsers jar+dependencies available? (see http://wiki.apache.org/tika/Troubleshooting%20Tika) Does the Tika app work for you?
