<p>A RenderTexture is a special texture that allows any pixi displayObject to be rendered to it.</p>
<p><strong>Hint</strong>: All DisplayObjects (exmpl. Sprites) that renders on RenderTexture should be preloaded.
Otherwise black rectangles will be drawn instead. </p>
<p>RenderTexture takes snapshot of DisplayObject passed to render method. If DisplayObject is passed to render method, position and rotation of it will be ignored. For example:</p>
<pre class="code prettyprint"><code>var renderTexture = new PIXI.RenderTexture(800, 600);
var sprite = PIXI.Sprite.fromImage("spinObj_01.png");
sprite.position.x = 800/2;
sprite.position.y = 600/2;
sprite.anchor.x = 0.5;
sprite.anchor.y = 0.5;
renderTexture.render(sprite);
</code></pre>
<p>Sprite in this case will be rendered to 0,0 position. To render this sprite at center DisplayObjectContainer should be used:</p>
<pre class="code prettyprint"><code>var doc = new PIXI.DisplayObjectContainer();
doc.addChild(sprite);
renderTexture.render(doc); // Renders to center of renderTexture
</code></pre>
