> Key: TIKA-3122
> URL: https://issues.apache.org/jira/browse/TIKA-3122
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Minor
> Fix For: 1.25
>
>
> There are some use cases where you'd like to know how many images are on a page and what formats those images are, but rendering every image can be expensive.
>
> Let's add an option to extract the PDImageXObject's metadata and the image mime for each embedded file.
>
> For an example of of a file with a crazy number of inline images, see: https://corpora.tika.apache.org/base/docs/govdocs1/113/113019.pdf
