Hello everyone, I'm a JavaCV newbie. Now, I want to draw line over 4 vertices of rotated rect. I stuck in step get vertices[4] from rotated rect. So I need a help. Thank everyone.

I saw in source code opencv_core.RoatatedRect and it has function points(Point[] points), but when I integrated javacv 1.1, javacpp 1.1 and opencv 3.0.0 RotatedRect has function points(Point2f pts). Why?. Please explain for me. Thank so much.

Point2f derives from FloatPointer, which has functionality for dealing
with native arrays, so we can access the 4 points you're interested in
this way, for example:
Point2f vertices = new Point2f(4);
rotatedRect.points(vertices);
float[] coordinates = new float[8];
vertices.get(coordinates);
