----------------------------Original message---------------------------- I am interested to learn about thematic map output with scanned topo map sheet as background layer on the CalComp-68436. We want to use scanned raster topo sheets (combined or single map elements layers) as a neutral background in grey scale rasterized with thematic color overlays. The CC-68436 is in upgrading process with a "big" 760 MB disc, but we still haven't experienced with scanned pixel base map (also halftone images c'd be possible in the near future). Any thoughts and hints available? Thanks, ---------------------------------------------------------------------- Frank Hoffmann, DD [This message is printed on 100 % recycled electrons]
