Function Documentation

NppStatus nppiGetRotateBound	(	NppiRect	oSrcROI,
		double	aBoundingBox[2][2],
		double	nAngle,
		double	nShiftX,
		double	nShiftY
	)

Compute bounding-box of rotated image.

Parameters

oSrcROI	Region-of-interest of the source image.
aBoundingBox	Two 2D points representing the bounding-box of the rotated image. All four points from nppiGetRotateQuad are contained inside the axis-aligned rectangle spanned by the the two points of this bounding box.
nAngle	The rotation angle.
nShiftX	Post-rotation shift in x-direction.
nShiftY	Post-rotation shift in y-direction.

NppStatus nppiGetRotateQuad	(	NppiRect	oSrcROI,
		double	aQuad[4][2],
		double	nAngle,
		double	nShiftX,
		double	nShiftY
	)

Compute shape of rotated image.

Parameters

oSrcROI	Region-of-interest of the source image.
aQuad	Array of 2D points. These points are the locations of the corners of the rotated ROI.
nAngle	The rotation nAngle.
nShiftX	Post-rotation shift in x-direction
nShiftY	Post-rotation shift in y-direction
