NAME

       YIQRGB - Converts a color specification given in the YIQ color space to the equivalent
       color specification in the Red, Green, Blue (RGB) color space.

SYNOPSIS

       CALL YIQRGB (Y, I, Q, R, G, B)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_yiqrgb (float y, float i, float q, float *r,
       float *g, float *b)

DESCRIPTION

       Y           (REAL, input, range [0.,1.])  specifies the color component of a television
                   signal that is shown on black-and-white televisions; Y minimizes the effect of
                   two colors appearing different to the human eye but mapping to similar
                   monochrome intensities.

       I           (REAL, input, range [-.6,.6])

       Q           (REAL, input, range [-.52,.52])

       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.

EXAMPLES

       Use the ncargex command to see the following relevant examples: tcolcv, fcce02.

ACCESS

       To use YIQRGB or c_yiqrgb, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.
