<div class="box intro">
<p>A RenderTexture is a special texture that allows any Pixi display object to be rendered to it.</p>
<p><strong>Hint</strong>: All DisplayObjects (i.e. Sprites) that render to a RenderTexture should be preloaded otherwise black rectangles will be drawn instead.</p>
<p>A RenderTexture takes a snapshot of any Display Object given to its render method. The position and rotation of the given Display Objects is ignored. For example:</p>
<p> 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);</p>
<p>The Sprite in this case will be rendered to a position of 0,0. To render this sprite at its actual position a DisplayObjectContainer should be used:</p>
<p> var doc = new PIXI.DisplayObjectContainer();
doc.addChild(sprite);
renderTexture.render(doc); // Renders to center of renderTexture</p>
