The map <EM>name</EM> should be an available raster map layer in the user's current mapset search path and location. <P> <H3>Parameters:</H3> <DL> <DT><B>map=</B><EM>name</EM> <DD>Name of a raster map layer in the user's current mapset search path whose color table is to be displayed. <DT><B>color=</B><EM>name</EM> <DD>Color of the lines separating the colors of the color table. <BR> Options: red, orange, yellow, green, blue, indigo, violet, gray, white</B>, and black. <BR> Default: <EM>white</EM> <DT><B>lines=</B><EM>value</EM> <DD>Number of lines to appear in the color table. <BR> Options: 1 - 1000 <DT><B>cols=</B><EM>value</EM> <DD>Number of columns to appear in the color table. <BR> Options: 1 - 1000 If the <EM>value</B>s</EM> of both <EM>lines</EM> and <EM>cols</EM> are not specified by the user, <EM>d.colortable</EM> divides the active frame equally among the number of categories present in the named raster map layer. If one option is specified, the other is automatically set to accommodate all categories. If both are specified, as many categories as possible are displayed. </DL> <P> The user can specify all needed parameters on the command line using the form: <P> <DL> <DD> <B>d.colortable map=</B><EM>name</EM> [<B>color=</B><EM>name</EM>] [<B>lines=</B><EM>value</EM>] [<B>cols=</B><EM>value</EM>] </DL> <P> If the user specifies the name of a map on the command line but does not specify the values of other parameters, parameter default values will be used. Alternately, if the user types simply <B>d.colortable</B> on the command line without any program arguments, the program will prompt the user for parameter settings using the standard GRASS <A HREF="parser.html">parser</A> interface described in the manual entry for <EM><A HREF="parser.html">parser</A></B>.</EM> <H2>EXAMPLE</H2> The user running the command: <DL> <DD> <B>d.colortable map=</B><EM>soils</EM> [<B>color=</B><EM>red</EM>] [<B>lines=</B><EM>1</EM>] [<B>cols=</B><EM>3</EM>] </DL> would see the active graphics frame divided into three columns extending the full frame height. The lines dividing the color table associated with the <EM>soils</EM> map would be displayed in red. The user would see, at most, only three of the colors from the <EM>soils</EM> color table displayed in the active frame (because the user requested that this frame be divided into three sections). <H2>NOTES</H2> If the user wishes to display the entire color table associated with a map, the user should either stipulate a number of lines (rows) and columns (cols) sufficient to accommodate the number of categories in the map's color table, or fail to assign values to one or both of <EM>lines</EM> and/or <EM>cols</B>.</EM> If the user runs <EM>d.colortable</EM> using the default number of lines and columns (the full graphics frame), all categories from the map's color table will be displayed. However, if the user requests that the color table associated with a map which has 10 data categories be displayed in a graphics frame with only 3 lines (rows) and 2 columns (a total of six cells), only six of the ten map categories will be displayed. <P> The user should run the GRASS program <EM><A HREF="d.erase.html">d.erase</A></EM> between runs of <EM>d.colortable</EM> to avoid confusion. <H2>SEE ALSO</H2> <EM><A HREF="d.colors.html">d.colors</A></EM><br> <EM><A HREF="d.erase.html">d.erase</A></EM><br> <EM><A HREF="d.rast.html">d.rast</A></EM><br> <EM><A HREF="parser.html">parser</A></EM> <H2>AUTHOR</H2> James Westervelt, U.S. Army Construction Engineering Research Laboratory <p><i>Last changed: $Date: 2007-04-11 15:45:53 +0200 (Wed, 11 Apr 2007) $</i> <HR> <P><a href="index.html">Main index</a> - <a href="display.html">display index</a> - <a href="full_index.html">Full index</a></P> <P>© 2003-2008 <a href="http://grass.osgeo.org">GRASS Development Team</a></p> </body> </html>
