## 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.
Returns
ROI Related Error Codes.
 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
Returns
ROI Related Error Codes.
