In 8 bit, you can change the color map or use "ncolor" and change the color indicies without redrawing the plot. 2) copy $GEMTBL/colors/coltbl.xwp to your working directory and set the first color to white iinstead of black. or, if running ntl to set the color map 3) Edit $NAWIPS/resource/Ntop, and uncomment the last line: Ntop*appbgName: white > > > 2) Does gpmap support the TXTFIL and TXTLOC commands?
