<hr><a name="_details"></a><h2>Detailed Description</h2>
The path object (polylines, polygons, and generalizations).
<p>
This object follows the PDF rendering model, but is actually a bit more complicated since we add new subtypes: arcs, parabolas, uniform B-splines (in PDF, all of these are converted to cubic Bezier splines). Unlike Ipe 5, we can now represent objects consisting of more than one subpath. Note that Ipe 5's spline and arc objects are now represented as <a class="el" href="class_ipe_path.html">IpePath</a> objects.<p>
A path object consists of a set of subpaths (<a class="el" href="class_ipe_sub_path.html">IpeSubPath</a>), each of which is either open or closed, and which are rendered by stroking and filling as a whole. The distinction between open and closed is meaningful for stroking only, for filling any open subpath is implicitely closed. Stroking a set of subpaths is identical to stroking them individually. This is not true for filling: using several subpaths, one can construct objects with holes, and more complicated pattern. The filling algorithm is the <b>even-odd rule</b> of PDF: To determine whether a point lies inside the filled shape, draw a ray from that point in any direction, and count the number of path segments that cross the ray. If this number is odd, the point is inside; if even, the point is outside. (<a class="el" href="class_ipe_path.html">IpePath</a> objects can also render using the <b>winding fill rule</b> by setting the StrokeStyle attribute. This isn't really supported by the Ipe user interface, which doesn't show the orientation of paths.)<p>
A subpath consists of a sequence of segments. (A complete ellipse and a closed B-spline curve can appear as special cases of subpaths that cannot be further decomposed into segments.) Segments are either straight, a quadratic Bezier spline, a cubic Bezier spline, an elliptic arc, or a uniform cubic B-spline. The segmented subpath class <a class="el" href="class_ipe_segment_sub_path.html">IpeSegmentSubPath</a> returns segments as <a class="el" href="class_ipe_path_segment.html">IpePathSegment</a> (but they are not internally stored that way).
