Class: BaseRenderTexture

PIXI.BaseRenderTexture

A BaseRenderTexture is a special texture that allows any PixiJS display object to be rendered to it.

Hint: All DisplayObjects (i.e. Sprites) that render to a BaseRenderTexture should be preloaded otherwise black rectangles will be drawn instead.

A BaseRenderTexture 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:

let renderer = PIXI.autoDetectRenderer();
let baseRenderTexture = new PIXI.BaseRenderTexture({ width: 800, height: 600 });
let renderTexture = new PIXI.RenderTexture(baseRenderTexture);
let sprite = PIXI.Sprite.from("spinObj_01.png");

sprite.position.x = 800/2;
sprite.position.y = 600/2;
sprite.anchor.x = 0.5;
sprite.anchor.y = 0.5;

renderer.render(sprite, {renderTexture});

The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0 you can clear the transform


sprite.setTransform()

let baseRenderTexture = new PIXI.BaseRenderTexture({ width: 100, height: 100 });
let renderTexture = new PIXI.RenderTexture(baseRenderTexture);

renderer.render(sprite, {renderTexture});  // Renders to center of RenderTexture

Extends

Members

filterStack Array<any>

The data structure for the filters.

maskStack Array<PIXI.MaskData>

The data structure for the stencil masks.

_canvasRenderTarget PIXI.utils.CanvasRenderTarget protected

A reference to the canvas render target (we only need one as this can be shared across renderers)

Default Value:
  • undefined

Methods

destroy () void overrides

BaseRenderTexture.ts:128

Destroys this texture.

dispose () void overrides

BaseRenderTexture.ts:115

Frees the texture and framebuffer from WebGL memory without destroying this texture object. This means you can still use the texture later which will upload it to GPU memory again.

Fires:

resize (desiredWidth, desiredHeight) void

BaseRenderTexture.ts:104

Resizes the BaseRenderTexture.

Name Type Description
desiredWidth number

The desired width to resize to.
desiredHeight number

The desired height to resize to.
