[jira] [Comment Edited] (TIKA-1445) Figure out how to add Image
metadata extraction to Tesseract parser
[ https://issues.apache.org/jira/browse/TIKA-1445?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14267101#comment-14267101 ]

-----------------------------------------------------------
I'm sorry that I haven't had a chance to kick the tires on the fix for this issue. This may be a case of user error, perhaps I have to twiddle with the parser config file?
I found that the current fix (with default configuration) is not pulling metadata from embedded image files in tika-trunk or tika-1.7-rc2.
Test doc from govdocs1 attached.
We should be extracting these values (at least) in the embedded tiff:
{noformat}
"Data Precision":"8 bits","Image Height":"169 pixels","Image Width":"752 pixels","Number of Components":"3","Resolution Units":"inch","X Resolution":"300 dots","Y Resolution":"300 dots","resourceName":"image1.jpg","tiff:BitsPerSample":"8","tiff:ImageLength":"169","tiff:ImageWidth":"752","tika.mime.file":"image1.jpg"
{noformat}

> Now that Tesseract is the default image parser in Tika for many image types, consider how to add back in the metadata extraction capabilities by the other Image parsers.
