double GetRed

(

Tcolor *

c

)

Gets the red component of a color.

Parameters:

c

The color to query.

Returns:

The red component of the color.

double GetGreen

(

Tcolor *

c

)

Gets the green component of a color.

Parameters:

c

The color to query.

Returns:

The green component of the color.

double GetBlue

(

Tcolor *

c

)

Gets the blue component of a color.

Parameters:

c

The color to query.

Returns:

The blue component of the color.

void PrintColor	(	FILE *	f,
		Tcolor *	c
	)

Prints the three components of a color in a file.

The componts (red, blue, and green) are printed as doubles, without any separation mark. This is the way in which Geomview uses colors.

Parameters:

	f	The file where to write the color
	c	The color to print.
