Here is the code to draw a single pixel line, black on white, on the
drawable "layer" and x1 y1 are one end and x2 y2 are the other.
(gimp-context-set-brush "Circle (01)")
(gimp-context-set-foreground "Black")
(gimp-context-set-background "White")
(gimp-context-set-opacity 100)
(gimp-context-set-paint-mode NORMAL-MODE)
(gimp-pencil layer 4 (vector x1 y1 x2 x2))
(gimp-displays-flush)
0,0 is upper left hand side. This is with the pencil tool. Replace
with any other tool as desired, for example:
(gimp-paintbrush-default layer 4 (vector x1 y1 x2 y2))
Hope that helps,
