Any significant overhead in calling $image->width() and height()

[DrQuincy]

When you access an image from the API you can get the width and height with $imade->width() and $image->height(). When you run these internally does ProcessWire get the sizes from the database or does it actually use GD to get them? I'm assuming if you aren't creating variations on the fly it just reads them from the database (the schema has width and height columns).

Just checking that there won't be any significant overhead if doing this on lots of images.

@Robin S brought up this issue not so long ago and it’s been fixed since. So yes it does pull from the database directly, see https://github.com/processwire/processwire-issues/issues/1812

Thanks!

So I guess since that github comment is ~3 months old you have to be on a fairly recent version for the performance increase.

It’s actually on the current master version (3.0.229) though the fix for svg files mentionned in the issue as well is only on the dev one
