[jira] [Resolved] (TIKA-1413) OOXML thumbnail name added to body
[ https://issues.apache.org/jira/browse/TIKA-1413?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hong-Thai Nguyen resolved TIKA-1413.
------------------------------------
Resolution: Fixed
> OOXML thumbnail name added to body
> ----------------------------------
>
> Key: TIKA-1413
> URL: https://issues.apache.org/jira/browse/TIKA-1413
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.6
> Reporter: Andrzej Bialecki
>
> AbstractOOXMLExtractor.handleThumbnail processes thumbnails using EmbeddedDocumentExtractor, but with the outputHtml flag set to true (unlike other embedded parts in handleEmbeddedParts(...)).
> This results in adding the thumbnail name to the main body of the document (as a package-entry), which in my opinion is wrong.
> Example:
> {code}
> <?xml version="1.0" encoding="UTF-8"?><html xmlns="http://www.w3.org/1999/xhtml">
> <head>
> <meta name="meta:slide-count" content="1"/>

> <div class="embedded" id="thumbnail_0.jpeg"/><div class="package-entry"><h1>thumbnail_0.jpeg</h1></div></body></html>
> {code}
> The extracted plain text looks like this (using tika-app):
> {code}
> The quick brown fox jumps over the lazy dog
> thumbnail_0.jpeg
> {code}
> The fix is trivial - change the flag in AbstractOOXMLExtractor:158 to false.
> I think also that the id attribute should be set to the real thumbnail path within the package (i.e. tPart.getPartName().getName()) instead of the artificially created sequential name.
