PixiJS

Class: Framebuffer

PIXI.Framebuffer

A framebuffer can be used to render contents off of the screen. PIXI.BaseRenderTexture uses one internally to render into itself. You can attach a depth or stencil buffer to a framebuffer.

On WebGL 2 machines, shaders can output to multiple textures simultaneously with GLSL 300 ES.

new PIXI.Framebuffer (width, height)

Framebuffer.ts:50
Name Type Description
width number

Width of the frame buffer
height number

Height of the frame buffer

Members

colorTexture PIXI.BaseTexture readonly

Reference to the colorTexture.

height number

Height of framebuffer in pixels.

multisample PIXI.MSAA_QUALITY

Desired number of samples for antialiasing. 0 means AA should not be used.

Experimental WebGL2 feature, allows to use antialiasing in individual renderTextures. Antialiasing is the same as for main buffer with renderer antialias:true options. Seriously affects GPU memory consumption and GPU performance.

 renderTexture.framebuffer.multisample = PIXI.MSAA_QUALITY.HIGH;
 //...
 renderer.render(myContainer, {renderTexture});
 renderer.framebuffer.blit(); // copies data from MSAA framebuffer to texture
Default Value:
  • PIXI.MSAA_QUALITY.NONE

width number

Width of framebuffer in pixels.
