Scale a landscape image taken from a camera to use it in a portrait

In my application, I take pictures imagewith the camera and use UIImagePickerit to squeeze it. But the problem is that when I shoot the image from the camera in landscape mode, while hacking it in potrait mode, a black box is displayed on the image.

The image is taken in landscape mode -

but I want to remove the black parts to imagecover the whole area.

How can i do this?
