Phpthumb(like) options for thumb()?

I need to use a little more sophisticated image resize options than thumb() seems to be offering. In this case I would like to use the hp and wl options, that phpthumb is offering (height for portrait, width for landscape).
Is there a plugin supporting this or do I just revert to phpthumb and do it myself?


Ok, everything back to start - the default thumb() actually does have the droids I’m looking for.
When I enter a width and height as arguments, it treats those values as max values, just as I wanted it. I was expecting it to force those values, thereby distorting the image (which it does not).
So all is good as is.

(Thanks though, @fanningert!)
