[Mp4-tech] Cropping in JPEG

[Mayank Agarwal]

Hi all,
I am trying to implement Cropping in JPEG.Suppose there is the decode r 
output YUV image of size 288*224
and i want to crop it to a size of 112*112 then what could be the possible 
approaches:
One approach is to modify the final output buffer at the end of each Y/U/V 
component to the required size
but i am not getting the correct Output.If anyone has worked on this 
previously,he can be of some help.
Regards,
Mayank
