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.
