You can use the line command, with a pattern, to get the alternating black and
white you need.  If you need the line to consist of more colors than that, then
you'll need to write a line algorithm.

I did this a -long- time ago, and the general idea of thi particular method was:

Find which difference was greater, x1-x2 or y1-y2.
 (if the same, it doesn't matter which you pick as the lesser or greater)
 (We'll say in this example that x1-x2 is greater)
Slope = (y1-y2)/(x1-x2)  (Lesser difference over greater difference)
for count = x1 to x2  (this is the greater distance to travel, by going on
                       it, we won't miss any pixels on the line, nor draw
                       any extra pixels.)
   putxy count, (count * slope)
next count

That should do it.  I didn't test it here (I don't have the original program)
but if you have any problems, email me about it.  Please note that it will be
*very* slow compared to any built in line routines.  If you need faster lines,
consider using C and write a DLL or OCX to do the work for you.
