Simon Lucy commented on TIKA-3348:
-----------------------------------
It's a pretty straightforward use case, extracting images from containers
(usually PDFs), to reuse them but in context with the original content. For
example, it's not uncommon for a publisher to present articles with the images
extracted as figures and used as navigation. That's similar to my use case. But
the general use case of extracting images for reuse from PDFs is common.
> Improve the workflow for extracting and returning images from PDFs and other
> containers using Tika Server..

> Key: TIKA-3348
> URL: https://issues.apache.org/jira/browse/TIKA-3348
> Project: Tika
> Issue Type: Improvement
> Components: server
> Affects Versions: 1.25
> Reporter: Simon Lucy
> Priority: Major
> Fix For: 2.0.0
>
>
> There's a set of bumps in the road to navigate when extracting images from
> PDFs, retrieving them and managing the metadata using Tika Server.
> The first is knowing that /unpack will do the basic job and return the
> embedded objects in a zip file (presuming setExtractInlineImages is True).
> Documenting this clearly in the Tika Server wiki page would help people
> enormously.
> But processing those images after they've been extracted will either need
> inspecting with another tool or using /rmeta to return the mime types and the
> rest of the metadata.
> This means that multiple passes need to be made over the same file and the
> same processes of extraction, identification and temporary storage will be
> made over.
> The server processes of /rmeta and /unpack need to be melded. The simplest
> may be to generate /rmeta metadata in the __META__ file object added to the
> returned zip file. A more complicated but perhaps more hypermedia way would
> be to use Content Negotiation and indicate an Accept application/zip in the
> /rmeta request.
> I've indicated a Fix version of 2.0 because it is if not a breaking change a
> considerable one.
> I'm available for Help Wanted, if that helps.
