Increasing the size of a sprite

Hi, I am increasing the size of a sprite from size 0,0 gradually to it gets 150,150, but how do I stop it when it reaches this size.

Appreciate any help here

Cheers

matthew

if sprite height is <= 150, 150

and

if sprite width is <= 150, 150

then increase the size. (otherwise, it won't)

Sorted!

Thank you.
