Constructor & Destructor Documentation

Rgba32() [1/6]

SIMD_INLINE Rgba32	(	const uint8_t &	gray = uint8_t(0),
		const uint8_t &	a = uint8_t(255)
	)

Creates a new 32-bit RGBA pixel structure with specified channel values.

Parameters

[in]	gray	- initial value for all channels. It is equal to 0 by default.
[in]	a	- initial value for alpha channel. It is equal to 255 by default.

Rgba32() [2/6]

SIMD_INLINE Rgba32	(	const uint8_t &	r,
		const uint8_t &	g,
		const uint8_t &	b,

	)

Creates a new 32-bit RGBA pixel structure with specified channel values.

Parameters

[in]	r	- initial value for red channel.
[in]	g	- initial value for green channel.
[in]	b	- initial value for blue channel.
[in]	a	- initial value for alpha channel. It is equal to 255 by default.
