no, i meant sheer or stretch, i know about enlargement.

astarmathsandphysics:
When youstretch you still need a direction of stretch starting from a certain point. I think therefore that it would be negastive if stretched by the same facture in the other direction.

Till now I cant handle the shear and enlargement thing in transformations thing!
