.TH HSVRGB 3NCARG "March 1993" UNIX "NCAR GRAPHICS" .na .nh .SH NAME HSVRGB - Converts a color specification given in the Hue, Saturation, and Value (HSV) color space to color values in the Red, Green, Blue (RGB) color space. .SH SYNOPSIS CALL HSVRGB (H, S, V, R, G, B) .SH C-BINDING SYNOPSIS #include .sp void c_hsvrgb (float h, float s, float v, float *r, .br float *g, float *b) .SH DESCRIPTION .IP H 12 (REAL, input, range [0.,360.) ) represents the hue of the input color in HSV color space. .IP S 12 (REAL, input, range [0.,1.]) represents the saturation value of the input color in HSV color space. Saturation is a measure of how much white light is mixed with the color. Saturation values of 0. represent grays (with a gray value equal to the value V). Saturation values of 1. are fully saturated colors. The hue is undefined when S=0. The fully saturated pure hues occur when S=1. and V=1. .IP V 12 (REAL, input, range [0.,1.]) represents the value of the input color in HSV color space. .IP R 12 (REAL, output, range [0.,1.]) represents the red intensity component of the output color in RGB color space. .IP G 12 (REAL, output, range [0.,1.]) represents the green intensity component of the output color in RGB color space. .IP B 12 (REAL, output, range [0.,1.]) represents the blue intensity component of the output color in RGB color space. .SH C-BINDING DESCRIPTION The C-binding argument descriptions are the same as the FORTRAN argument descriptions. .SH EXAMPLES Use the ncargex command to see the following relevant examples: coex03, tcolcv, fcce02. .SH ACCESS To use HSVRGB or c_hsvrgb, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order. .SH MESSAGES See the colconv man page for a description of all Colconv error messages and/or informational messages. .SH SEE ALSO Online: colconv, hlsrgb, rgbhls, rgbhsv, rgbyiq, yiqrgb, ncarg_cbind. .sp Hardcopy: NCAR Graphics Fundamentals, UNIX Version .SH COPYRIGHT Copyright (C) 1987-2009 .br University Corporation for Atmospheric Research .br The use of this Software is governed by a License Agreement.
