[jira] [Updated] (TIKA-1612) Exceptions getting image data in PPT files

["Tim Allison (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TIKA-1612?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Allison updated TIKA-1612:
------------------------------
    Attachment: engine_monitoring.png
                image.bin

When I save the image as via PowerPoint, I get the engine_monitoring.png file.

When I call "getRawBytes", I get the image.bin file, which does look compressed but doesn't appear to have a header.

> In numerous (~500) ppt files in govdocs1, we're getting zip exceptions (unknown compression method, bad block, etc) when Tika's HSLFExtractor calls {{getData()}} on an embedded image.
> Under normal circumstances (I just learned today...), if an attachment causes a RuntimeException, we are currently swallowing that in {{ParsingEmbeddedDocumentExtractor}}.
> However, because we're calling {{getData()}} before the embedded extractor takes over, if there is an exception there, the parse of the entire file fails.
