once again : double click on the "Straight line selections" tool, set up
the slider to the number of pixels you want, and you're done.

Alternatively, you can get the selection dialog with "Edit/Otpions/Line
width..."

This works for straight lines, and the resulting ROI is still considered
as a line, not a surface, with subtle ways to process things like
intensities along the line, I think averaging in the direction
perpendicular to the line for each point - correct me if I'm wrong but I
seem to remember a discussion about that on the list.
