Subject [jira] [Updated] (TIKA-1033) Tika doesn't parse embedded OLE Chart/Graph objects
Date Tue, 05 Apr 2016 01:30:25 GMT

     [ https://issues.apache.org/jira/browse/TIKA-1033?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tim Allison updated TIKA-1033:
------------------------------
    Attachment: testMSChart-govdocs-428996.pptx

When I saved the .ppt file that I submitted over on TIKA-1651 as a pptx, PowerPoint saved
the same embedded vnd.ms-chart object as is in "embeddings".

> I have an example ppt that embeds a chart, but Tika mis-identifies it

> The progID (oleShape.getProgID() in
> HSLFExtractor.handleSlideEmbeddedResources) is MSGraph.Chart.8 ... and
> we seem to detect it as Excel (application/vnd.ms-excel) but then the
> ExcelExtractor hits this exception:
> {noformat}

> Since DelegatingParser silently suppresses all exceptions, when you

> run with -z, it will save 1.xls which if you then try to parse with
> TikaCLI hits the above exception.
