Function imageproc::drawing::draw_line_segment

pub fn draw_line_segment<I>(image: &I,
                            start: (f32, f32),
                            end: (f32, f32),
                            color: I::Pixel)
                            -> VecBuffer<I::Pixel> where I: GenericImage, I::Pixel: 'static

Draws as much of the line segment between start and end as lies inside the image bounds. Uses Bresenham's line drawing algorithm.
