Indeed it is long gone many releases ago. AFAIK the limit was 300M cells for greyscale and 100M cells for RGB rasters. as others have mentioned, defeating default ghostscript options often solves the 72dpi PDF hardcopy problem. See: http://grass.osgeo.org/wiki/Ps.map_scripts#Converting_PostScript_to_PDF ps2pdf -dPDFSETTINGS=/prepress -r1200 filename.ps (72dpi is usually fine for the screen or for projector presentations, but not the printed page) and from the ps.map man page: The resolution and extent of raster maps plotted with ps.map are controlled by the current region settings via the g.region module. The output filesize is largely a function of the region resolution, so special care should be taken if working with large raster datasets. For example if the desired output is US- Letter sized paper at 300dpi, with 1" margins and the raster filling the entire page, the usable area on the page will be 6.5" x 9", which at 300 dots/inch is equivalent to a region of 1950 columns x 2700 rows (see "g.region -p"). Any higher reso- lution settings will make the output file larger, but with a consumer printer you probably won't be able to resolve any bet- ter detail in the hardcopy. regards, Hamish _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
