Gimp: drawing a thin line?

thanks

It seems I needed to Edit the Brush...Hardness and Radius settings impact the line thickness.

I can get it thinner, but not 1 pixel...

here is an example of: Brush sizes - 1, 3 and 5 pixels; Stroke path - 1 pixel and pencil - 1 pixel:

I guess my Mac version is very different than yours...

do you think that you could post  a screenshot like this (select Paint brush & show Tool options tab)?

here it is...

Thanks -

first of all, to display the Menu bar (as in my screenshot) use the Mac mouse button that displays the context menu ANYWHERE in the image pane (I think it is the right mouse button) click on View and click on Show Menubar.

now the menubar at the top should be displayed.

does your Gimp screen now look something like this? (i added the YELLOW)

I see Show Manubar was checked...

if you prefer, you can use Single-Window Mode

instead of having 3 separate windows and a new window for each open window, your open images will now be tabbed in the main image pane

place the 3 panes side by side with the image pane in the middle

click on Windows menu ―> Single-Window Mode

you GIMP interface will now look like this:this is much more practical... but, i'm right-handed, so i prefer the tools on the fight

The Mac does not see to allow me to put the tools on the right...

you really have to place the 3 panes in the CORRECT order

go back to the Windows menu, uncheck the Single-Window Mode and place the 3 panes EXACTLY as shown here:once this is done, go back to the Windows menu, check the Single-Window Mode problem solved

I can not do that on a Mac...

And I decided to use Paintbrush for the thin line.

You can pick your stroke size, no headaches. I give up on GIMP for this feature.Thanks for all the help.
