Do I need to make every image power of 2(Android) for better performance?
For example how could I make this: http://starbounder.org/mediawiki/images/1/18/Pixel_Hero_Set.png
picture po2 without stretching it?
My problem was that I wanted to keep the aspect ratio, and by stretching it to po2 it won't keep the aspect ratio. So to keep the aspect ratio and make it po2 I need to add transparent space to the image(in this case on the left and on the right handside) and I wanted to know if this decreases the performance.
Otherwise, if you are in charge of the art, just make it in power of two to start with.
