Program for digitizing graphs

Python program for digitizing graphs with error bars: points of a certain purpose (origin, axes, graph points, error points) are added with the mouse, boundary values for the axes are set, after which the script calculates the coordinates of the entered points and writes them to a text file. The program allows working with logarithmic scales of the axes, and additionally, time intervals can be set along the x-axis. The input image of the graph can be oriented arbitrarily and may have linear distortions, allowing the processing of graph scans without prior editing in a graphic editor.
