I have a sprite sheet for a character that is a fairly standard 32x32 sprite. This remains for most of the animations in the sprite sheet. However, for some animations (swinging a sword being the most obvious example), the total area of the sprite extends 8-16px in whatever direction the animation happens in.
What are some solutions for dealing with this?
Attached two images of the sprite with a grid to give you an idea of what I mean.
