Would the "See Alignment" spell work on invisible creatures?

The description says:

DESCRIPTION
When you cast this spell, select a single alignment (such as lawful good or chaotic evil). Creatures of that alignment glow with a ghostly radiance while they are within your vision. Though you can see this radiance, other creatures cannot. Spells and effects that obscure alignment, like undetectable alignment, also obscure the effects of this spell.

The phrase "within your vision" seems to imply that the spell would not affect a creature under an invisibility spell, but one could argue otherwise.

EDIT: The rationale for the argument is that a perception check would allow a character to find an invisible foe. Moreover, the creature is there even though invisible, so its alignment is "there".

Actually, now that I think about it, the spell wouldn't really be much use now. I had thought of multiclassing my Zen Archer into Sorcerer (Empyreal) but given the 1 round/level duration, I would need at least 2 levels in Sorcerer to get any use from the spell. If I cast the spell, I might be able to see my invisible opponent, but I would not be able to do anything about it. The next round, when I could shoot, I wouldn't be able to see it any more.

Look for threads on detect magic. It would work the same way.

The thread I found seems to imply that it ought to work. I only I could make effective use of it...

Well it would require three rounds of concentration and stop working the moment you started firing yourbow...

See alignment doesn't require concentration; the duration is simply one round per level.
