Function imageproc::drawing::draw_antialiased_line_segment_mut

pub fn draw_antialiased_line_segment_mut<I, B>(image: &mut I,
                                               start: (i32, i32),
                                               end: (i32, i32),
                                               color: I::Pixel,
                                               blend: B) 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.
