Is there a function similar to rbbox that draws a line from corner to corner?

I am currently using rbbox to select a point on the axis and draw a ray to some other point. The rbbox draws the outline of the rectangle as I drag the mouse cursor around. When rbbox is done, I draw the line from the starting corner to the ending corner. However, my goal is to make a line parallel to a feature on the axis (image) and I find that I cannot do this precisely being able to see only the rectangle outline. I'd really like rbbox to draw a line corner-to-corner as I drag the mouse cursor. Is there a function similar to rbbox that can help me with this? Or do I need to write my own "real-time" line drawer?

How about imline() or improfile()?

"imline" class looks like it will do the job nicely, thank you. I do happen to have the Image Processing toolbox at my disposal, so this solution should work. It's funny how this "function" has no command line help, nor does it auto-complete. But the HTML doc is complete.
