Detailed Description

The Color class: Implements a 4 component RGBA color.

Constructor & Destructor Documentation

GlsColor ( void  )

inline

Red, Green, Blue, Alpha 0-255 range default constructor. Intializes rgba data to zero

GlsColor ( unsigned char  r, unsigned char  g, unsigned char  b, unsigned char  a = 255  )

inline

4ub constructor. Intializes using rgba values

Parameters

r	Red value, range 0-255
g	Green value, range 0-255
b	Blue value, range 0-255
a	Alpha value, range 0-255

GlsColor ( const unsigned char  newColor[] )

inline

4ubv constructor. Intializes using rgba value

Parameters

newColor

4 character RGBA array, range 0-255

GlsColor ( unsigned long  rgbaVal )

inline

4ul constructor.

Parameters

rgbaVal

Unsigned long containing color in the form RRGGBBAA (8 bits per component

GlsColor ( const GlsColor &  color )

inline

copy constructor.
