Oil brush: The oil brush gives a true brush look.Its effect is much like the marker's except that the thickness of the strokes change as you speed up and slow down the pen's movement. Calligraphy pen: This tool works like you'd expect a calligraphy pen to work.Neighboring pixels that are just out of reach are lightly colored. It's similar to the pixel pen tool, except that it will bleed parts of the color into nearby pixels for a softer approach. Marker: The marker has a uniform stroke everywhere it's used and has a clean, full look to it.
