/**
|
|
* A RenderTexture is a special texture that allows any Pixi display object to be rendered to it.
|
|
*
|
|
* __Hint__: All DisplayObjects (i.e. Sprites) that render to a RenderTexture should be preloaded otherwise black rectangles will be drawn instead.
|
|
*
|
|
* 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:
|
|
*
|
|
* 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);
|
|
*
|
|
* 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:
|
|
*
|
