		int	nDstClipY1 = 0,
		int	nDstClipX2 = -1,
		int	nDstClipY2 = -1
	)

Transfers a block of image data.

The function transfers a block of image data from one source buffer to another using given copy policy.

Note:

The clipping rectangle is <nDstX1, nDstX2) & <nDstY1, nDstY2)

		typename TDwPcy::PxFmt_t *	pDst,
		int	nDstW,
		int	nDstH
	)
