If you consider that the Gimp canvas is measured from the top left corner 0,0 as shown by the rulers. Show with a one pixel pencil. [...]
To get a pointer value of 100, 20 you need to go outside the canvas.[...]
When for example I collected image coordinates to create curves with the Ofn-luminosity-masks script, the X = 1000 point was always off canvas, I had to "manually adjust" the value for that point, since in the Pointer window N / A.
It would be nice to have Pointer and Ruler speaking the same language.
Thx Rich!

I have only used Gimp after version 2.10.1, which was the first version this computer saw. Always portable versions of Samj.
My profile is correct, although I have rotated between versions 2.10.12 and 2.10.14, I use the first one because I find it more reliable and the second use with addon-manager, and other tests.

The coordinates on the Pointer dialog are the coordinates of the sampled pixel (so are always an integer...), so 188 is show when your cursor is anywhere between 188.0 and 188.999...)
In 2.10 things are different, the position indicator is a floating point value, so the pointer dialog always shows the "floor" of the cursor position.
In the two versions cited above (.12 and .14) the situation is the same as described in the first post, as illustrated in the image attached there.
I thought it was a simple matter of configuration to synchronize these readings.
Thx Ofnuts!
