title: IOS - CoreImage composite one image to another image at specific location
body: <p>Sorry if I am posting a duplicated question.</p>
  
  <p>I am newbie in IOS programming with CoreImage. I am going to composite an image over another image.
  The problem is the Composite filters from Core image don't support a composition at specific location. It is compositing the two images at the location (0,0) only. </p>
  
  <p>For example, I need to composite an image at the location (100,100) of another image, not at the left-top corner. </p>
  
  <p>Any suggestion for this issue must be appreciated.</p>
