NAME

       HLSRGB - Converts a color specification given as Hue, Lightness, and Saturation (HLS)
       values to Red, Green, and Blue (RGB) intensity values.

SYNOPSIS

       CALL HLSRGB ( H, L, S, R, G, B )

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_hlsrgb (float h, float l, float s, float *r,
       float *g, float *b)

DESCRIPTION

       H           (REAL, input, range [0.,360.) ) represents the hue of the input color in HLS
                   color space. H=0.  corresponds to blue.

       L           (REAL, input, range [0.,100.])  represents the lightness value of the input
                   color in HLS color space.  Lightness is a measure of the quantity of light - a
                   lightness of 0. is black, and a lightness of 100.  gives white. The pure hues
                   occur at lightness value 50.

       S           (REAL, input, range [0.,100.])  represents the saturation value of the input
                   color in HLS color space.  Saturation is a measure of how much white light is
                   mixed with the color. Colors having a saturation value of 0. represent grays
                   with a gray intensity value equal to the lightness L.  Colors with a
                   saturation value of 100. are fully saturated colors. The hue is undefined when
                   S=0.  The fully saturated pure hues occur when S=100.  and L=50.

       R           (REAL, output, range [0.,1.])  represents the red intensity component of the
                   output color in RGB color space.

       G           (REAL, output, range [0.,1.])  represents the green intensity component of the
                   output color in RGB color space.

       B           (REAL, output, range [0.,1.])  represents the blue intensity component of the
                   output color in RGB color space.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.
