NppStatus nppiGetRotateBound | ( | NppiRect | oSrcROI, |
double | aBoundingBox[2][2], | ||
double | nAngle, | ||
double | nShiftX, | ||
double | nShiftY | ||
) |
Compute bounding-box of rotated image.
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.
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 |
