this is the code to make the circular bitmap which is used in the image views of android.
at the end of the code the circle mode of bitmap is created by the enum mode.

this is the code to make the circular bitmap and use it in the image views and other viewers in android technology.
at the end of the code the circle mode of bitmap is created by the en um Mode.
