Talk:E-book comb.as

Those diffs are pretty revealing ay? ;-)

• TR → TL (uses Tx to flip right to left)
• TR → BR (uses Ty to flip top to bottom)

Notice that the differences can all be expressed as simple changes of sign of an item in some of the expressions. Tx is -1 or +1, Ty is -1, 0 or +1. Tx and Ty use those values so that they can be used as multipliers to either change the sign of what they multiplied with (if its -1) or leave it unchanged if its +1.

Yep thats helpful, ta. I've passed the variables into the function now so I'm happy Jack 23:40, 20 Dec 2006 (NZST)

I'll wait until you've cleaned it up and reduced to single function using tx,ty before looking at that lot I think --Nad 09:05, 21 Dec 2006 (NZST)
