#!N #!N Syntax #!N  #!F-adobe-times-bold-r-normal--18*   #include <dx/dx.h> Error DXColorNameToRGB(char *colorname, RGBColor 
*rgbvalue) #!EF #!N #!N Functional Details #!N #!N The RGB values 
of the color string  #!F-adobe-times-bold-r-normal--18*   colorname #!EF are obtained from a 
color lookup table and returned in  #!F-adobe-times-bold-r-normal--18*   *rgbvalue #!EF . For 
example, the RGB values for the color "white" are 1.0, 1.0, 
1.0. The color lookup table could come from a number of 
places: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o The 
routine first checks the environment variable DXCOLORS. If that is set, 
the routine uses the value of the variable and tries to 
open it as a file. #!N #!I30 #!N o If that 
does not succeed, the routine then checks the environment variables DXEXECROOT 
and DXROOT for a directory path. It will append /lib/colors.txt to 
this path and try to open the file. If that fails, 
it tries to open /usr/lpp/dx/lib/colors.txt. #!N #!I30 #!N o If none 
of these files can be opened, the routine uses an internal 
static table. This table is a subset of colors in the 
file /usr/lpp/dx/lib/colors.txt. #!N #!I0 #!N #!EF #!N #!N #!N Return Value 
#!N #!N Returns  #!F-adobe-times-bold-r-normal--18*   OK #!EF or returns  #!F-adobe-times-bold-r-normal--18*   ERROR #!EF 
and sets an error code. #!N #!N See Also #!N #!N
