Does anyone know of a tool or add-in that will give me the image pixel location of marked points on images or lines from the tracker? I would also ideally like to be able to programatically plot points on images or on overlays of the images.

Hi,
I'm not sure it's what you are looking for, but you can get the coordinates of the points of a trajectory by using the export to spreadsheet function, from the file menu.
Currently there is no way to get them directly from within the software, you have to export them.
I would also ideally like to be able to programatically plot points on images or on overlays of the images.
You could try to programmatically generate a .kva file and then import it. ("Load Key Images data…" menu)
.kva is the XML description of the key images and drawings. There is currently no shema or DTD, but you could set a few points and export them to see how the format works.
I am interested in knowing more about your workflow and what you are doing, picked my curiosity 
Thanks for your reply I will try what you say. I am trying to use position of tracked item on the images to determine a simple way to assess how sports actions compare between students and experts. Position and motion over time of limbs and equipment and position and motion of other objects such a s ball etc are critical. I need to plot these as well to provide comparative feedback to the users.
