Function imageproc::drawing::draw_antialiased_line_segment

pub fn draw_antialiased_line_segment<I, B>(image: &I,
                                           start: (i32, i32),
                                           end: (i32, i32),
                                           color: I::Pixel,
                                           blend: B)
                                           -> VecBuffer<I::Pixel> where I: GenericImage,
        I::Pixel: 'static,
        B: Fn(I::Pixel, I::Pixel, f32) -> I::Pixel

Draws as much of the line segment between start and end as lies inside the image bounds. The parameters of blend are (line_color, original_color, line_weight). Uses Xu's line drawing algorithm.
