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....

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

  • That is way easier than what I suggested. You should do that. – Michiel Jan 12 '11 at 09:06
  • Thanks Xandy and Michiel for the information.. How do i get the x and y positions from the rectangle coordinates?? – uday Jan 12 '11 at 09:21
  • What's the type of object you hold the coordinates? – xandy Jan 12 '11 at 10:35
  • The type of object is Rect. I can able to get left, top, right, bottom from this object. and i dont know how to get x and y coordinates from the Rect object?? – uday Jan 12 '11 at 11:19

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.
