new PIXI.RenderTexturePool (textureOptions)

Name Type Attributes Description
textureOptions IBaseTextureOptions <optional>

options that will be passed to BaseRenderTexture constructor

textureOptions.scaleMode PIXI.SCALE_MODES <optional>

See PIXI.SCALE_MODES for possible values.


PIXI.RenderTexturePool.SCREEN_KEY number static

Key that is used to store fullscreen renderTextures in a pool

Automatically sets to true after setScreenSize

Default Value:
  • false


clear (destroyTextures) void

Clears the pool.

Name Type Attributes Description
destroyTextures boolean <optional>

Destroy all stored textures.

createTexture (realWidth, realHeight, multisample) PIXI.RenderTexture

Creates texture with params that were specified in pool constructor.

Name Type Description
realWidth number

Width of texture in pixels.

realHeight number

Height of texture in pixels.


Number of samples of the framebuffer.

Type Description

getFilterTexture (input, resolution, multisample) PIXI.RenderTexture

Gets extra texture of the same size as input renderTexture

getFilterTexture(input, 0.5) or getFilterTexture(0.5, input)

Name Type Attributes Description
input PIXI.RenderTexture

renderTexture from which size and resolution will be copied

resolution number <optional>

override resolution of the renderTexture It overrides, it does not multiply

multisample PIXI.MSAA_QUALITY <optional>

number of samples of the renderTexture

Type Description

getOptimalTexture (minWidth, minHeight, resolution, multisample) PIXI.RenderTexture

Gets a Power-of-Two render texture or fullScreen texture

Name Type Default Description
minWidth number

The minimum width of the render texture.

minHeight number

The minimum height of the render texture.

resolution 1

The resolution of the render texture.


Number of samples of the render texture.

Type Description
PIXI.RenderTexture The new render texture.

returnFilterTexture (renderTexture) void

Name Type Description
renderTexture PIXI.RenderTexture

The renderTexture to free

returnTexture (renderTexture) void

Name Type Description
renderTexture PIXI.RenderTexture

The renderTexture to free

setScreenSize (size) void

If screen size was changed, drops all screen-sized textures, sets new screen size, sets enableFullScreen to true

Size is measured in pixels, renderer.view can be passed here, not renderer.screen

Name Type Description
size ISize
