Class: RenderTexture

PIXI.RenderTexture

A RenderTexture 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 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. For example:

let renderer = PIXI.autoDetectRenderer(1024, 1024, { view: canvas, ratio: 1 });
let renderTexture = PIXI.RenderTexture.create(800, 600);
let 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;

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 renderTexture = new PIXI.RenderTexture.create(100, 100);

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

new PIXI.RenderTexture(baseRenderTexture, frame)

RenderTexture.js:43
Name Type Description
baseRenderTexture PIXI.BaseRenderTexture

The renderer used for this RenderTexture
frame PIXI.Rectangle optional

The rectangle frame of the texture to show

Extends

Members

_framePIXI.Rectangle inherited

This is the area of the BaseTexture image to actually copy to the Canvas / WebGL when rendering, irrespective of the actual frame size or placement (which can be influenced by trimmed texture atlases)

baseTexturePIXI.BaseTexture inherited

The base texture that this texture uses.

framePIXI.Rectangle inherited

The frame specifies the region of the base texture that this texture uses.

heightnumber inherited

The height of the Texture in pixels.

noFrameboolean inherited

Does this Texture have any frame data assigned to it?

origPIXI.Rectangle inherited

This is the area of original texture, before it was put in atlas

requiresUpdateboolean inherited

This will let a renderer know that a texture has been updated (used mainly for webGL uv updates)

rotatenumber inherited

Indicates whether the texture is rotated inside the atlas set to 2 to compensate for texture packer rotation set to 6 to compensate for spine packer rotation can be used to rotate or mirror sprites See PIXI.GroupD8 for explanation

textureCacheIdsArray.<string> inherited

The ids under which this Texture has been added to the texture cache. This is automatically set as long as Texture.addToCache is used, but may not be set if a Texture is added directly to the TextureCache array.

trimPIXI.Rectangle inherited

This is the trimmed area of original texture, before it was put in atlas

validboolean overrides

This will let the renderer know if the texture is valid. If it's not then it cannot be rendered.

widthnumber inherited

The width of the Texture in pixels.

Methods

PIXI.RenderTexture.create(width, height, scaleMode, resolution)PIXI.RenderTexturestatic

RenderTexture.js:125

A short hand way of creating a render texture.

Name Type Default Description
width number 100 optional

The width of the render texture
height number 100 optional

The height of the render texture
scaleMode number PIXI.settings.SCALE_MODE optional

See PIXI.SCALE_MODES for possible values
resolution number 1 optional

The resolution / device pixel ratio of the texture being generated
Returns:
Type Description
PIXI.RenderTexture The new render texture

_updateUvs()protected inherited

Texture.js:275

Updates the internal WebGL UV cache.

clone()PIXI.Texture inherited

Texture.js:265

Creates a new texture object that acts the same as this one.

Returns:
Type Description
PIXI.Texture The new texture

destroy(destroyBase) inherited

Texture.js:227

Destroys this texture

Name Type Default Description
destroyBase boolean false optional

Whether to destroy the base texture as well

resize(width, height, doNotResizeBaseTexture)

RenderTexture.js:100

Resizes the RenderTexture.

Name Type Description
width number

The width to resize to.
height number

The height to resize to.
doNotResizeBaseTexture boolean

Should the baseTexture.width and height values be resized as well?

setFrame(frame) inherited

deprecation.js:868
Name Type Description
frame PIXI.Rectangle

The frame to set.
Deprecated
  • since version 3.0.0
    See:

    update() inherited

    Texture.js:177

    Updates this texture on the gpu.

    Events

    update inherited

    Texture.js:147

    Fired when the texture is updated. This happens if the frame or the baseTexture is updated.

    Name Type Description
    texture PIXI.Texture

    Instance of texture being updated.
