I have a set of vector lines (which represent translation vectors for georeferencing). Based on the layer CRS, how can I compute the coordinates of each line in an attribute table ?
i.e (Xmax-Xmin; Ymax-Ymin) for each line.
I have managed to get the line length with $length in the expression editor but I am struggling with other geometrical parameters.
Edit: I am looking to "store the formula" within the layer. The idea is to keep these values automatically updated with the geometry. (Auto)update should happen if a new line is added or modification of the current geometry is done.
