Compass function to return Image Dimensions

[Richard Aday]

Is there something like image_url() that can return the height or width of an image?

This functionality could allow us to make our CSS even more flexible regardless of whatever image size is used.

Nope. That would be awesome, but it can't introduce any dependencies to compass.

Chris,

If we don't introduce a dependency (like image science or rmagick), then the only way to do this would be to implement our own ruby code that does what those dependencies already do...

Is that really better then having a dependency?

Yes. All images have headers that allow you to extract their size in the first few bytes. I've done it in C before. It's really not hard.

Are those headers consistent across different types of images (png, jpg, gif, etc)?

[Richard Aday]

I guess this could be a start for the Ruby code that does that:

Of course not.

That's the ticket.
