The colorization of imagery in McIDAS displays is controlled by the ehancement associated with the frame. You can change the mapping of image levels to display colors using the EU (Ehancement Utility) command. The first thing to do is use EU to list ouf the table of colors you are currently using: EU LIST Then figure out which colors you would like to change, and finally use EU to change the range(s) of colors to get the display you like. The form of the EU command you will be using to do this is: EU MAKE inlo inhi bcolor ecolor bframe eframe <keywords> Here is the online help for the EU command: EU -- Enhancement utility EU COLORS EU DEL name EU LIST string EU MAKE inlo inhi bcolor ecolor bframe eframe <keywords> EU MAKE inlo inhi 1lo 1hi 2lo 2hi 3lo 3hi bframe eframe <keywords> EU REST name bframe eframe <keywords> EU SAVE name EU TABLE name <keywords> Parameters: COLORS | lists the predefined colors in the MCRGB.TXT data file for use in the bcolor and ecolor parameters DEL | deletes a saved enhancement LIST | lists the saved enhancements MAKE | sets the enhancement REST | restores a saved enhancement (def) SAVE | saves the current enhancement TABLE | lists the values of an enhancement name | enhancement name; 512 characters maximum (REST option def=default grayscale enhancement; TABLE option def=current; no default for DEL and SAVE options) string | lists only the enhancements beginning with this character string (no default; list all enhancements) inlo | lowest brightness value of displayed image to apply the MAKE enhancement change to; the range is 0-255 (def=0); the resultant changes in color from inlo to inhi are done by interpolation from bcolor to ecolor or 1lo,2lo,3lo to 1hi,2hi,3hi inhi | highest brightness value of displayed image to apply the MAKE enhancement change to; the range is 0-255 (def=0) bcolor | predefined color to apply to inlo; use EU COLORS to list the valid colors ecolor | predefined color to apply to inhi (def=bcolor); use EU COLORS to list the valid colors 1lo | intensity of first color component to apply to inlo 1hi | intensity of first color component to apply to inhi 2lo | intensity of second color component to apply to inlo 2hi | intensity of second color component to apply to inhi 3lo | intensity of third color component to apply to inlo 3hi | intensity of third color component to apply to inhi; the valid range for parameters 1lo,1hi,2lo,2hi,3lo,3hi is 0-255 and def=0; the first color component is either blue or red, the second color component is green, the third color component is either red or blue; see Remarks for explanation bframe | beginning image frame on which to apply enhancement (def=current) eframe | ending image frame on which to apply enhancement (def=bframe) Keywords: LOOP=YES | applies enhancement to all frames in the loop; overrides the bframe and eframe values (def=NO) RGB=YES | changes the order of the color components from the default (blue-green-red) to red-green-blue in the MAKE option's 1lo,1hi,2lo,2hi,3lo,3hi input parameters and the TABLE option's output listing (def=NO) Remarks: Parameters 1lo, 2lo, 3lo and 1hi, 2hi, 3hi are the intensities (0-255) of the three color components that make up the final color applied to the inlo and inhi input brightness values. The RGB keyword determines the order in which the three color components are specified: - If RGB=YES is specified, then the color order is red, green, blue (1lo and 1hi are RED intensities, 2lo and 2hi are GREEN intensities, and 3lo and 3hi are BLUE intensities). - If RGB=NO (the default), then the color order is blue, green, red (1lo and 1hi are BLUE intensities, 2lo and 2hi are GREEN intensities, and lo and 3hi are RED intensities). Use command EB for interactive, mouse-controlled contrast stretching. ---------- >Also, on the WWDISP i am trying only the watches...but there is a label >that says warnings...anyway to get rid of that? It seems like you should be able to specify just the displays you want using the TYPE= keyword of WWDISP: TYPe=t1..tn | bulletin type(s) to plot; you cannot use TYPE with the WATCH keyword; valid TYPEs are SEVWARN,SEVWATCH,TORWARN, TORWATCH,WINWARN,WINWATCH,BLIZZARD,SNOWADV,FLOODWARN, FLOODWATCH,ALL (def=ALL), where: SEVWARN, SEVWATCH=severe thunderstorm warnings, watches TORWARN, TORWATCH=tornado warnings, watches WINWARN, WINWATCH=winter storm warnings, watches BLIZZARD=blizzard warnings, SNOWADV=snow advisories FLOODWARN, FLOODWATCH=flood/flash flood warnings, watches ALL=all of the above I am not at a workstation where I can actually test to make sure that the labeling is left off for displays you don't want (current home machine is windows, argh!) , but it seems like you should be able to include something like: WWDISP TYPE=SEVWATCH TORWATCH WINWATCH FLOODWATCH Have you tried this?
