Engauge Digitizer - Better Accuracy


To get better accuracy in the digitized output data exported from Engauge Digitizer, it is helpful to understand that all points are only as accurate as the pixel size (you can see that accuracy in the status bar). If the distance in graph units from one pixel to the next is D, then theoretically the best possible accuracy is also D.

It is not possible to define points that are 'between' pixels, even by zooming in closer. That is a constraint imposed by the graphics library that is used in Engauge Digitizer.

Fortunately, there are some tricks to improve the accuracy. In order of increasing difficulty:
