Hi.
Activate RTP(RealTimePreview) on small image (3x3 pixels). Move mouse to BottomRigth RTP corner, press and look at x,y.
You will see wrong x:1 , y:1.
Best regards,
Nikolay.
PS This error sends the wrong coordinates into the function virtual void pcl::ProcessInterface::UpdateReadout ( const View & v, const DPoint & p, double R, double G, double B, double A )
