Constructor & Destructor Documentation

PixelConstBuffer() [1/4]

PixelConstBuffer ( )

default

PixelConstBuffer() [2/4]

PixelConstBuffer

(

const PixelConstBuffer &

src

)

Copy constructor.

PixelConstBuffer() [3/4]

PixelConstBuffer	(	const PixelConstBuffer &	src,
		Int	offset
	)

Copy constructor with alignment.

PixelConstBuffer() [4/4]

PixelConstBuffer	(	const Pix *	buffer,
		BITS	inc
	)

Constructs the helper object.

Parameters

[in]	buffer	Pointer to the memory block of the pixel data.
[in]	inc	Distance in number of bytes from one pixel to the next. For packed pixels this value is equal to BytesPerPixel().
