                         digital halftoning processes. We show that the dot size is the 
                         main factor determining the tradeoff between tonal and spatial 
                         resolution in the context of dithering algorithms. In particular, 
                         we extend the dither with space filling curves method, introduced 
                         in (Velho \& Gomes, 1991), to change the size of pixel clusters 
                         according to local characteristics of the image. This makes 
                         possible to achieve optimal rendition of gray shades while 
                         preserving image details.",
