      <p class="para_topic">This style creates a very 'painterly' effect, with strokes and swirls of color which reflect and represent the orientation of the underlying geometry. The effect may also be interpreted as being akin to using colored pencils to shade the image (with the direction of the pencil strokes matching the underlying geometry at all times).</p>
      <p class="para_topic">Normally the colors of the strokes would be taken from the color of the objects being represented. However, you can override this so that a particular 'line color' is used. In this case, the effect is similar to a pencil drawing done using a single color of pencil.</p>
      <p class="para_topic">You can also alter the length and density of each stroke. A low value for the line or stroke length lends a finer, more detailed appearance to the final image. A low value for the density of the strokes results in more of the background, or paper, color showing through. It therefore makes sense to use an image of either paper or canvas as the background. A light color for the background is likely to look more appropriate in many cases.</p>
