Scale a sprite from the center, not the origin

Hello, I have a flat image representing a sprite and I've set the sprite origin to the bottomLeft. When I use scaleLocal() it scales the image from the origin. Can I set the scale from the center? I'm using scaleLocal() to mirror the image.

 

The most important question here is what 2D framework are you using?
I'm assuming your using a framework because you list a specific origin and scaleLocal() as a function, which doesn't exist in the Unity API.

 

Add scale * (pivot - center) to the position you want.

 

Sorry I'm using localScale(); (http://unity3d.com/support/documentation/ScriptReference/Transform-localScale.html).

I'm using 2dToolKit, but i've set all the sprites origin to the lower left so that all the sprites animate correctly. I contact the guy who made 2dToolKit and asked him for advice and he pointed me in the direction of localScale(). What I'm trying to do is flip the images horizontally, so that the sprite can walk both left and right. The issue is that they're getting flipped by the origin, so they "jump" from left to right.
