Scaling images for display includes determining if a nearest neighbor algorithm has been selected for scaling pixels of an image and, if so, finding the nearest neighbor using a linear interpolation algorithm. In particular, the disclosure relates to a method and user equipment for power scaling on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and an enhanced Dedicated Physical Data Channel, E-DPDCH are configured for uplink transmission from the UE to the receiving RAN. An approximation of said first image at said first viewpoint is determined an based on the first and second sets of features and the second image at the second viewpoint. Using a first phase shift mask having line-and-space patterns, the photoresist layer is exposed, forming first exposure regions.
