As a result, I get a slightly layered deeper image, and I definitely get something that&#8217;s difficult to capture with a camera. Thanks for checking it out!<\/p>\n<h3>Tracing Bitmaps in Inkscape<\/h3>\n<p>&#8220;Currently Inkscape employs the Potrace bitmap tracing engine (potrace.sourceforge.net) by Peter Selinger. In the future we expect to allow alternate tracing programs; for now, however, this fine tool is more than sufficient for our needs. \u00a0Keep in mind that the Tracer&#8217;s purpose is not to reproduce an exact duplicate of the original image; nor is it intended to produce a final product. No autotracer can do that. What it does is give you a set of curves which you can use as a resource for your drawing. \u00a0Potrace interprets a black and white bitmap, and produces a set of curves. For Potrace, we currently have three types of input filters to convert from the raw image to something that Potrace can use. \u00a0Generally the more dark pixels in the intermediate bitmap, the more tracing that Potrace will perform. As the amount of tracing increases, more CPU time will be required, and the  element will become much larger. It is suggested that the user experiment with lighter intermediate images first, getting gradually darker to get the desired proportion and complexity of the output path. \u00a0To use the tracer, load or import an image, select it, and select the Path &gt; Trace Bitmap item, or Shift+Alt+B.&#8221; &#8211; Inkscape tutorial: Tracing | Inkscape, <\/p>\n<div class=\"zemanta-pixie\" style=\"margin-top:
