Macro Definition Documentation

n_GColorFromHEX

#define n_GColorFromHEX

(

_h

)

Value:

n_GColorFromRGB(((_h) >> 16) & 0b11111111, \
                                            ((_h) >>  8) & 0b11111111, \
                                             (_h)        & 0b11111111)

Convenience macro to create the closest n_GColor to a hex value (eg 0xFF7700).

n_GColorFromRGB

#define n_GColorFromRGB	(		_r,
			_g,
			_b
	)

Value:

((n_GColor8) {{.a =               0b11, .r = ((_r) >> 6) & 0b11,\
                   .g = ((_g) >> 6) & 0b11, .b = ((_b) >> 6) & 0b11}})

Convenience macro to create the closest n_GColor to 3 8-bit values.

n_GColorFromRGBA

#define n_GColorFromRGBA	(		_r,
			_g,
			_b,
			_a
	)

Value:

((n_GColor8) {{.a = ((_a) >> 6) & 0b11, .r = ((_r) >> 6) & 0b11,\
                   .g = ((_g) >> 6) & 0b11, .b = ((_b) >> 6) & 0b11}})

Convenience macro to create the closest n_GColor to 4 8-bit values.
