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, -Rob A> _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
