<p>A Shape is a <a href="GraphObject.html">GraphObject</a> that shows a geometric figure.
The <a href="Geometry.html">Geometry</a> determines what is drawn;
the properties <a href="Shape.html#fill">fill</a> and <a href="Shape.html#stroke">stroke</a>
(and other stroke properties) determine how it is drawn.</p>
<p>There are generally two types of shapes: Those that use a custom <a href="Geometry.html">Geometry</a> by setting
<a href="Shape.html#geometry">Shape.geometry</a>, and those that receive an automatically generated Geometry using the value of
<a href="Shape.html#figure">figure</a>, <a href="Shape.html#toArrow">toArrow</a>, or <a href="Shape.html#fromArrow">fromArrow</a>. An explicitly set Geometry always supersedes
the figure and arrowhead properties.</p>
<p>Some created Shapes:</p>
<pre><code class="lang-js"><span class="hljs-keyword">var</span> $ = go.GraphObject.make; <span class="hljs-comment">// for conciseness in defining GraphObjects</span>
<span class="hljs-comment">// A shape with the figure set to RoundedRectangle:</span>

<span class="hljs-comment">// Alternatively:</span>
$(go.Shape, <span class="hljs-string">"RoundedRectangle"</span>, { <span class="hljs-attr">fill</span>: <span class="hljs-string">"lightgreen"</span> })
<span class="hljs-comment">// A shape with a custom geometry, using geometryString:</span>

);
</code></pre>
<p><p class="box">
You can see more custom geometry examples and read about geometryString
on the <a href="../../intro/geometry.html">Geometry Path Strings Introduction page.</a></p>
<p>When automatically generating a Shape <a href="Geometry.html">Geometry</a>, the value of <a href="Shape.html#toArrow">toArrow</a> takes precedence,
then <a href="Shape.html#fromArrow">fromArrow</a>, then <a href="Shape.html#figure">figure</a>. If the value of <a href="Shape.html#toArrow">toArrow</a> or <a href="Shape.html#fromArrow">fromArrow</a> is "None"
then it is ignored, and the "None" value of <a href="Shape.html#figure">figure</a> is identical to "Rectangle".</p>
<p>All of the predefined figures are shown in the <a href="../../samples/shapes.html">Shapes sample</a>.
You can define your own named figures by calling the static function <a href="Shape.html#static-defineFigureGenerator">Shape.defineFigureGenerator</a>.
Get a <a href="Map.html">Map</a> of named figures by calling the static function <a href="Shape.html#static-getFigureGenerators">Shape.getFigureGenerators</a>.</p>
<p>All of the predefined arrowheads are shown in the <a href="../../samples/arrowheads.html">Arrowheads sample</a>.
You can define your own named arrowheads by calling the static function <a href="Shape.html#static-defineArrowheadGeometry">Shape.defineArrowheadGeometry</a>.
Get a <a href="Map.html">Map</a> of named arrowheads by calling the static function <a href="Shape.html#static-getArrowheadGeometries">Shape.getArrowheadGeometries</a>.</p>
<p>You can see a copy of all of the built-in arrowhead definitions in this file: <a href="../../extensions/Arrowheads.js">Arrowheads.js</a>.</p>
<p>The Shape properties <a href="Shape.html#parameter1">parameter1</a>, and <a href="Shape.html#parameter2">parameter2</a> determine details of the
construction of some <a href="Shape.html#figure">figure</a> geometries.
Specifically, they often set the <a href="Shape.html#spot1">spot1</a>, <a href="Shape.html#spot2">spot2</a> for the Shape.
These spots determine the "inner area" of an Auto panel when a Shape is the main object.
See the <a href="../../intro/panels.html">Auto Panels section of the Panels Introduction page</a> for more details.</p>
<p>Shapes use their geometric bounds when determining hit testing,
but use rectangular bounds when participating in (panel) layouts.</p>

<p>This static function returns a read-only Map of named geometry generators.
The keys are figure names.
The values are either string synonyms for other figure names, or functions
that take a <a href="Shape.html">Shape</a> and a width and a height and return a <a href="Geometry.html">Geometry</a>.</p>
<p>The predefined shape figures can be seen in the <a href="../../samples/shapes.html">Shapes sample</a>.</p>
