1.get Width and Height .

2.Storage format：Config

　　Giving a Bitmap file of 1200*800,stored in RGB_565 format.Then one pixel consume 16 bits,1byte=8bit,so:

　　size=1200*800*16/8=192000byte=1.831M

 

　　if the format is RGBA_8888,then one pixel consume 32 bits:

　　size=1200*800*32/8=192000byte=3.662M
