How to get ROI of an image in Android

I have an image file (.jpg) which contains image like Face. From my application i want to capture that particular Face part and copy that part into a new bitmap file. I have a rectangular co-ordinates of that Face part, so how do i capture only Face part from the image file and copy that into a bitmap file??

Could any body help me to get rid of this problem....

You could use 

bitmap1.getPixel(x,y)

on the source image and using

bitmap2.setPixel(x,y,color)

on the destination image.

There is also a respective 

bitmap1.getPixels( pixelArray, offset, stride, x, y, width, height)

which is undoubtedly faster.

Bitmap.createBitmap(Bitmap source, int x, int y, int width, int height) will do the creation. For save, read this: Save bitmap to location
