RGB MAKE_RGB ( int color_index, int red, int green, int blue )

int color_index;   // An index into the standard palette (not necessary)

int red;           // An integer value between 0 and 255

int green;         // An integer value between 0 and 255

int blue;          // An integer value between 0 and 255

Synopsis

#include "silver.h"

The MAKE_RGB macro creates an RGB data type that stores color information.

Parameters

color_index is an index into the standard palette. It has become irrelevant and should be zero.

red is the red component of an RGB value. When red is 0 there is no red contribution. When red is 255 the red contribution is maximized.

green is the green component of an RGB value. When green is 0 there is no green contribution. When green is 255 the green contribution is maximized.

blue is the blue component of an RGB value. When blue is 0 there is no blue contribution. When blue is 255 the blue contribution is maximized.

Return Value

MAKE_RGB returns an RGB type that stores color information.

Remarks

The color_index parameter was preserved for legacy purposes, and should be 0, since SilverScreen stores all of its color information as rgb values.
