I have compared these two different kind of ways: The values, which are printed out are different. There must be something i am doing wrong:

Point2f rectPoints = new Point2f(4);
rotRect.points(rectPoints);
float[] coordinates = new float[8];
rectPoints.get(coordinates);

If I log the coordinates[idx] with idx from 0 to 7, i will receive my correct 8 coordinates:
{ 315.5, 219.5, 262.0, 166.0, 313.5, 114.5, 367.0, 168.0 }

If I log it this way here:

log.info(rectPoints.getPointer(0).x());
log.info(rectPoints.getPointer(0).y());
log.info(rectPoints.getPointer(1).x());
log.info(rectPoints.getPointer(1).y());
log.info(rectPoints.getPointer(2).x());
log.info(rectPoints.getPointer(2).y());
log.info(rectPoints.getPointer(3).x());
log.info(rectPoints.getPointer(3).y());

I will receive: {315.5, 219.5, 7.36E-32, -3.7E-34, 3169.7, 1.01E-42, 5.9E-32, -8.9E-42}
So, the first two coordinates are correct, the other six are more or less random.

Is there something I did not mention?

Thanks a again, for your help

Uh oh!

How can I draw a rotated Rectangle? #1556
