Generate thumbnails via command line

[sepastian]

No thumbnails have been generated for some objects.

I would like to trigger thumbnail generation, ideally on the command line, without having to recreate objects and/or upload media once more. Can this be done in omeka-s? How?

I read about the command line interface in #71.

Thanks for any pointers!

Anyone?

Hi there. Can you describe the objects that did not generate thumbnails? What kind of files are they?

At this time, I don't believe there's a way to trigger thumbnail generation from the command line.

Hello, thumbnails were not generated because of a missing dependency of ImageMagick under Alpine Linux inside Docker, see this commit for details.

I ended up using https://omeka.org/s/modules/CreateMissingThumbnails/, which creates all missing thumbnails.

It would be preferable to trigger the creation of missing thumbnails on the command line, though.

Out of curiosity: does Omeka S have a command line interface at all? That could be extended to provide that functionality?

We don't really have a CLI, no.

There's no particular reason one couldn't be made (jobs like the one you likely used with that module run "on the command line" essentially), but there isn't something preexisting that something like what you're talking about could hang off of.
