Abstract

The present disclosure relates to the re-sampling of pixel data, with one application being micro-lithography. In particular, it relates to a first pixel map, including a plurality of white, black and grey scale pixels and gradient directions for one or more of the grey scale pixels, that is resampled to produce a second pixel map using edge geometry data generated from the gradient directions and grey scale values.
