+ This simple tool helps you by generating code while you interactively
+ draw graphic paths. This was used to draw the <a href="graphics-violin.html">violin example</a>.

+ </a>
+</div>
+
+<h2>The Path Tool</h2>
+
+<p>As you drag the pencil icon, corresponding graphics code is auto-generated.
+This code can be copied and pasted into a graphics instance to reproduce
+the paths you created with the pencil.
+</p>
+
+
+<h2>Initial State</h2>
+<p>When the tool window is loaded, its generated code is placed
+in the text area control. The generated code assumes you will have a separate
+page to paste it into. This separate page must contain the following code:
+A graphics container such as this,</p>
+<pre class="code prettyprint"><div id="mygraphiccontainer"></div></pre>
+
+<p>CSS such as this,</p>
+<pre class="code prettyprint">#mygraphiccontainer {
+ position: relative;
+ width: 700px;
+ height:400px;
+}</pre>
+
+and a YUI instance containing a <code>Graphics</code> object such as this.
+<pre class="code prettyprint">YUI().use('graphics', function (Y) {
+
+ var mygraphic = new Y.Graphic({render:"#mygraphiccontainer"});
+ // generated code from the path tool goes here
+
+});</pre>
+
+<p>The tool generates paste-able code for an <code>addShape</code> method that will
+create and render a path. It generates some fill and stroke placeholder code.
+You can change this to change the attributes of the fill and stroke
+after it's pasted into your code.</p>
+<p><Strong>Note:</strong>
+As you draw paths with the pencil, they won't have these attributes; you'll
+only see thin, red lines for precision. The placeholder attributes below will
+only show after you paste the code in your page.</p>
+<pre class="code prettyprint">{
+ type: "path",
+ stroke: {
+ weight: 2,
+ color: "#00dd00"
+ },
+ fill: {
+ type: "linear",
+ stops: [
+ {color: "#cc0000", opacity: 1, offset: 0},
+ {color: "#00cc00", opacity: 0.3, offset: 0.8} // Opacity of stops not available in IE
+ ]
+ }
+}</pre>
+
+
+<h2>LineTo (Drag Pencil)</h2>
+<p>Drag the pencil icon. The <code>drag:end</code> event sets the <code>lineTo</code> XY value.</p>
+
+<h2>MoveTo (Shift + Drag)</h2>
+<p>Drag the pencil icon with the shift key down to move without drawing a line.</p>
+
+<h2>CurveTo (Alt + Drag)</h2>
+<p>Drag the pencil icon with the alt key down. This draws a curve and displays
+two draggable control points. The curve adjusts while you drag the control points.
+Clicking the pencil icon, or starting another line, finalizes the <code>curveTo</code>.</p>
+
+<h2>New Path Object</h2>
+<p>Crate a new path object with a new name by changing the name in the
+'Graphic Object Name' text input, then clicking the 'New' button.</p>
+
+<h2>Trace an Image</h2>
+<p>You can modify the CSS of #mygraphiccontainer to include an image background.
+This will allow you to trace the contours of an image.</p>
+
+<pre class="code prettyprint">#mygraphiccontainer {
+ background: url(assets/images/my-dog.jpg);
+}</pre>
+
+
+<img src="../assets/graphics/img/my-dog.jpg" alt="Tracing a picture of my dog
+with a Graphics path" width="652" height="268"/>
+
+zooming the browser can be helpful in accuracy.
