When do ask Tiled map map, too tile picture of how to do?

I now use tiledMap for a game map, the game tiles are different elements of the four directions and seven colors, each color and direction if given Dounong a tile picture, it will have 150 tiles Atlas 44 * 44 pixels in FIG. This is not the memory consumption will be too?

Alternatively, tile does not consider the direction and color, plus a objectLayer, add attributes in objectLayer, the program reads the map file, parse traversal object properties objectLayer, and then rotate and color. But this is not to deal with a lot of it, consumption performance?

I do not know how to choose, who has experience in this area is not?

150 tile are completely different yet? You can count on, if opengl es in the image aspect multiples of 2, if your figure is 24-bit color, then the total size is 150x64x64x24 / 8, probably about 1.8MB, I think it is acceptable
