boxPoints function

VecPoint2f boxPoints(
  1. RotatedRect rect, {
  2. VecPoint2f? pts,
})

BoxPoints finds the four vertices of a rotated rect. Useful to draw the rotated rectangle.

return: bottom left, top left, top right, bottom right For further Details, please see: https:///docs.opencv.org/3.3.0/d3/dc0/group__imgproc__shape.html#gaf78d467e024b4d7936cf9397185d2f5c

Implementation

VecPoint2f boxPoints(RotatedRect rect, {VecPoint2f? pts}) {
  pts ??= VecPoint2f();
  cvRun(() => cimgproc.cv_boxPoints(rect.ref, pts!.ptr, ffi.nullptr));
  return pts;
}
