i'm not good in english i try to translate what you write and just tel me if i'm wrong or not
1- for example i have a sprite with width 80 and height 100 (with no transparanecy spaces)
then to avoid waste memory i have to make it as 100X100 with transparency spaces ?
what about the story about the 1 or 2 pixel around the sprite ?
2-is that same for tiled backgroud ? if the recommanded power of 2 is for example 128 X 128
then we have to put a png with 127x127 or 126 x 126 ?
i'm a little confused
