How I can get size from compressed texture?

I need a texture size after compression. Such information is in the preview window(look image linked below), and I do not know how I can get it. Of course I’m interesting in how to get this information from the editor.

Use Profiler.GetRuntimeMemorySize(), which will return the amount of memory consumed by the asset. Note that this will work not only for textures, but for any asset in the game.

Look here for more informations of compression values (bytes per pixel).

texture.height texture.width
