Description

It would be useful to be able to access file metadata from Scribunto, particularly the height and width of images. This has already been requested a couple of times on [[Wikipedia:Lua requests]]:

Is there any chance of getting a new library to enable this functionality?

Severity: enhancement

Specifically, this will be useful on Wikivoyage, where every main namespace page has a banner image which must have a 7:1 aspect ratio. We need a way to check and tag them automatically for cropping, instead of always checking the file pages one-by-one and doing the math.

I just come here to request the same. I was planning to write some code for automatically creating KML files for georeferencing map images, based on 3 anchor points where user provides latitude and longitude for 3 points on the map. Dimension of the image is one of the elements I would need to have. I was surprised to discover we could not access it.

This should probably be closed.

The height and width of an image was exposed to lua in https://gerrit.wikimedia.org/r/#/c/136274/

Or we might repurpose this one for https://gerrit.wikimedia.org/r/67588 instead of T43498?
