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.SEE ALSO
