NAME

6       HSVRGB - Converts a color specification given in the Hue, Saturation,
7       and Value (HSV) color space to color values in the Red, Green, Blue
8       (RGB) color space.

SYNOPSIS

11       CALL HSVRGB (H, S, V, R, G, B)
12

C-BINDING SYNOPSIS

14       #include <ncarg/ncargC.h>

16       void c_hsvrgb (float h, float s, float v, float *r,
17       float *g, float *b)

DESCRIPTION

20       H           (REAL, input, range [0.,360.) ) represents the hue of the
21                   input color in HSV color space.
22
23       S           (REAL, input, range [0.,1.])  represents the saturation
24                   value of the input color in HSV color space.  Saturation is
25                   a measure of how much white light is mixed with the color.
26                   Saturation values of 0.  represent grays (with a gray value
27                   equal to the value V). Saturation values of 1. are fully
28                   saturated colors.  The hue is undefined when S=0. The fully
29                   saturated pure hues occur when S=1. and V=1.
30
31       V           (REAL, input, range [0.,1.])  represents the value of the
32                   input color in HSV color space.
33
34       R           (REAL, output, range [0.,1.])  represents the red intensity
35                   component of the output color in RGB color space.
36
37       G           (REAL, output, range [0.,1.])  represents the green
38                   intensity component of the output color in RGB color space.
39
40       B           (REAL, output, range [0.,1.])  represents the blue
41                   intensity component of the output color in RGB color space.
42

C-BINDING DESCRIPTION

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

ACCESS

52       To use HSVRGB or c_hsvrgb, load the NCAR Graphics libraries ncarg,
53       ncarg_gks, and ncarg_c, preferably in that order.
