How to export pixel data to excel? - Razorclad - 12-02-2017
If you use a selection tool to select a perimeter of an object, is there a way to output the pixel locations (x and y) to excel?
RE: How to export pixel data to excel? - Ofnuts - 12-02-2017
If you convert the selection to a path (or if you just create the path around the object), I have a script to export the path (its "anchor" points, in particular) to a CSV file: see here.
The "Histogram" dialog (and the gimp_histogram() function for scripts) can tell you several things about the selection (count of pixels (all or within specified range), etc...).

However, paths are splines, made up of a finite set of nodes with 2 control points each.
When you export a path, you get an ASCII .XML file, which you can read.
I tried to write a plug-in to identify which pixels were lying under a path and quickly discovered it ain't trivial to figure out how to "proceed along the path from the initial node."

Uh? Not trivial, but not that difficult.
