I'm looking for a way to do a simple math operation on a variable before using it in a tag. Specifically, I'd like to generate a glide image url with a height based on a provided width, when given an aspect ratio. Glide doesn't appear to support an aspect ratio parameter, so I tried using a multiply modifier inside the tag.
I tried a few variations, but thought something like this would work:
{{ glide:image width="{w}" height="{w | multiply:2 }" }}
Doing it the following way output w in the height parameter, but didn't multiply it:
{{ glide:image width="{w}" height={w | multiply:2} }}
so either something is broken or I don't understand what's happening here (more likely).
Anyone have any idea what's going on here? Is the only option to create an addon to manage this calculation?
