Setting the origin of an object

Is it possible to, at runtime, change the origin of a bitmap/sprite? Say i am importing an image from an external source and then want to rotate said bitmap, is there a way to change it’s origin (i think that’s the right term for it) so that it doesn’t rotate from it’s top-left point? I have so far drawn a blank on searches to see if this is possible. Figured this would be the best place to get a quick yay or nay. :slight_smile:

Cheers folks.
