RGB to HSL

[sathya8819]

Hi, I have this following code for RGB to HSL conversion, but I do not know how to use it to display my image. Can someone help out

var_R = ( R / 255 )                     //RGB from 0 to 255
var_G = ( G / 255 )
var_B = ( B / 255 )

var_Min = min( var_R, var_G, var_B )    //Min. value of RGB
var_Max = max( var_R, var_G, var_B )    //Max. value of RGB
del_Max = var_Max - var_Min             //Delta RGB value

L = ( var_Max + var_Min ) / 2

if ( del_Max == 0 )                     //This is a gray, no chroma...
{
   H = 0                                //HSL results from 0 to 1
   S = 0
}
else                                    //Chromatic data...
{
   if ( L < 0.5 ) S = del_Max / ( var_Max + var_Min )
   else           S = del_Max / ( 2 - var_Max - var_Min )

   del_R = ( ( ( var_Max - var_R ) / 6 ) + ( del_Max / 2 ) ) / del_Max
   del_G = ( ( ( var_Max - var_G ) / 6 ) + ( del_Max / 2 ) ) / del_Max
   del_B = ( ( ( var_Max - var_B ) / 6 ) + ( del_Max / 2 ) ) / del_Max

   if      ( var_R == var_Max ) H = del_B - del_G
   else if ( var_G == var_Max ) H = ( 1 / 3 ) + del_R - del_B
   else if ( var_B == var_Max ) H = ( 2 / 3 ) + del_G - del_R

   if ( H < 0 ) ; H += 1
   if ( H > 1 ) ; H -= 1
}

Maybe this thread might shed a light on it http://www.daniweb.com/forums/thread236306.html
Also remember that every Color struct has a GetHue, GetSaturation and GetBrightness method.
