Abstract
The original image reproduced on a pixel raster is taken apart into a number of adjoining pixel structures and these are each replaced by a resolution-independent replacement surface, in accordance with rules described in the application. The replacement surfaces together form a resolution-independent intermediate image which is mapped on a new pixel raster with the required different resolution.
