Attachment: 03.doc
I'm sorry that I haven't had a chance to kick the tires on the fix for this
issue.
I just discovered that the current fix 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}

consider how to add back in the metadata extraction capabilities by the other
Image parsers.

[ https://issues.apache.org/jira/browse/TIKA-1445?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Tim Allison updated TIKA-1445: -- Attachment: TIKA-1445_tallison_v3_20141027.patch This version subclasses Parser to create an ImageMetaParser class, which our current image metadata parsers then extend. This adds a DefaultImageMetadataparser that is a copy and paste of DefaultParser...can't override static loader unfortunately! We now specify regular parsers in the Parser services file and ImageMetadataParsers in a separate services file. I don't like that this creates a new class of parsers, but I can't think of another way of guaranteeing that the OCRParser will find an image metadata parser correctly.

Attachment: TIKA-1445.Palsulich.102614.patch
Here is an updated patch with the above idea. I created a new public method in
CompositeParser and DefaultParser -- {{getAllParsersFor(ParseContext,
MediaType}} -- which returns a list of all Parsers that support the given type.
This list is then searched from TesseractOCRParser for a second Parser for the
image being parsed.
I created a dummy BodyContentHandler to drop all content from the second Parser.
Thoughts?
