See my attached demo for burning a line into an image. So just call imline() a bunch of times with different starting and ending points. Of course you need to have some kind of recipe for saying where the lines start and end. I think that you should easily be able to do that with simple trig functions like cosd() and sind() and knowledge of where the lines emanate from (which can be off the image). Give it a try and let us know if you can't figure it out. By the way, is this a homework assignment?
