It gives an estimate of error introduced by converting original datapoints into vector graph included in the PDF file.
If there are appreciable errors in ticks positioning you can reduce the error by fitting the coordinates of ticks to a linear model. This linear function now can be used to get original coordinates of points of the path that is in the coordinate system of the plot. Works in Linux and Windows. It's a free software and I have used it.
I had to do this so many times in my career I eventually put together a javascript program which is available here:. Sorry, but you will still need to click on every single point. Though you can use the arrow keys which does save some wrist strain.
