Thanks Nathan. With this option I can obtain the image characteristics but I don't know the option that indicates me the depth of the pixel. Width and Height are in outWidth and outHeight but I don't know where is the depth. I thought use the getRowBytes() of Bitmap and product it with getHeight() of Bitmap, but I don't know if there is correct.
