well in gimp (and also photoshop) u have this cutter and u just move the mouse around what u want to cut. now when u arent 100% on the edge which u want to cut, the programm knows that and will still cut that place. e.g. for a very long edge u can quickly move the mouse over it and the programm will cut this edge.. or if u follow smth else it always knows how to cut that. Hard to descripe in english
anyone got an answer for the resizing stuff?
thanks
