Due to an ongoing problem I want to try extruding my tileset for testing, I am writing a tool for my specific case. I understand how to extrude the edge, just repeat the side. But what about the corner, does it even matter in the case of Corona SDK?
It may matter, just use the original corner pixels for that.
Lets say you have a 3 by 3 image just do the following:
original image: 1,1 2,1 3,1 1,2 2,2 3,2 1,3 2,3 3,3 extruded image: [1,1][1,1][2,1][3,1][3,1] [1,1] 1,1 2,1 3,1 [3,1] [1,2] 1,2 2,2 3,2 [3,2] [1,3] 1,3 2,3 3,3 [3,3] [1,3][1,3][2,3][3,3][3,3]
You should take that extra step as its not hard to achieve.
