The line ramp tool alters a line of pixels between two specified points. Starting at the first points height it graduates the pixels to the second point's height, creating a ramp or bridge between the two points. After a line has been created, the line tool will use the final point of the last line as the start point of the next line, chaining the lines together.
Line Width: specifies how wide the line will be from point to point.
New Start: forces the line tool to
create a new start point. Useful if you
wish to start another set of lines that do not join the first set.
