drawing with subpixel precision

Hi all,
I’m pretty new to ImageJ and Image processing in general and currently working on an implementation for a point-tracking algorithm in ImageJ.
At the end of the algorithm I have particle positions along a trajectory (an array of Xs and Ys).
The position of the particles is with floating point precision (e.g. x= 12.98, y=23.01) and I would like to display the trajectory with this precision, possibly to animate it and save the original movie with the added trajectories displayed.
If I use the drawLine method then the minimum line width is 1 and I lose the precision.
I tried drawing on the ImageCanvas. That gives me the precision but I cant save it together with the original movie.
I will be happy to get any suggestions.
Guy
