Performance of drawing Lines

[arakis]

What is the most performant way to draw lots of short straight lines? Current code:

        public void Stroke()
        {
            var pathCollection = new PathCollection(Paths);
            Image.Mutate(ctx => ctx.Draw(Brush, StrokeThickness, pathCollection));
        }

As I can see, most time is spent on FindIntersections and Allocate.

When using

            var options = new ShapeGraphicsOptions
            {
                GraphicsOptions = new GraphicsOptions { Antialias = false, AlphaCompositionMode = PixelAlphaCompositionMode.Src },
            };

It's a little bit better (not much), but the result is ugly (the line is drawn correctly in "stairs-style", but it seems there's an ugly border around the lines - maybe I used a wrong AlphaCompositionMode mode.).
