Making a cone thing

Ok..

If I have a fat tube (or a rectangle really) on its own layer, how to I make it have a pointy end (like a tentacle). Ctrl-T does it okay, except it always changes the length and makes it fuzzy.

Now I'm somewhat happy with that, however, how do I make it less fuzzy? Make it look less anti-alialized?

Thanks a lot, if you want an example screenshot, tell me.

Start with a higher resolution...some even multiple of 72, such as 144 ppi or 288 ppi.

Do your transform, then scale it to the size you need.
