How in the world do the devs at Nexon rotate their sprites? I tried doing it myself in photoshop. Put the axis at the base of the spear, and rotated. I got the horribly pixellated mess on top:
The legit one from Maplestory is displayed at the bottom (horizontal position). After my first failure I attempted it with all the image interpolation types (bicubic, billinear, and the other four in general preferences) but it always becomes a pixellated mess. I presume the devs don't sprite 45 degree, 90 degree, and 180 degree positions from scratch (judging by how inefficient it would be, and how lazy Nexon is at doing things in general) but I'm puzzled as to how they managed this feat.
