Function Documentation

alphaComposit() [1/2]

omw::Color omw::alphaComposit	(	const omw::Color &	a,
		const omw::Color &	b
	)

Returns

Alpha composit of A over B

If one of the colors is invalid, the return value is also invalid. However all color values are computed anyway.

alphaComposit() [2/2]

int32_t omw::alphaComposit	(	int32_t	a_ACCC,
		int32_t	b_ACCC
	)

Returns

Alpha composit of A over B

Format: 0xAACCCCCC where CCCCCC is any combination of RR, GG and BB, and has to be consistent for input and return values.

alphaComposit_apply() [1/2]

void omw::alphaComposit_apply	(	const omw::Color &	a,
		omw::Color &	b
	)

Writes the alpha composit of A over B to B.

Parameters

a
b	[in/out]

If one of the colors is invalid, the result is also invalid. However all color values are computed anyway.

alphaComposit_apply() [2/2]

void omw::alphaComposit_apply	(	int32_t	a_ACCC,
		int32_t &	b_ACCC
	)

Writes the alpha composit of A over B to B.

Parameters

a_ACCC
b_ACCC	[in/out]

Format: 0xAACCCCCC where CCCCCC is any combination of RR, GG and BB, and has to be consistent for input and output values.
