Methods

bind

bind(baseTexture: BaseTexture): void
Bind to a parent BaseTexture
Parameters
- baseTexture: BaseTexture
  Parent texture
Returns void
Inherited from BaseImageResource.bind
- Defined in node_modules/@pixi/core/lib/textures/resources/Resource.d.ts:60

destroy

destroy(): void
Call when destroying resource, unbind any BaseTexture object before calling this method, as reference counts are maintained internally.

dispose

dispose(): void
Destroys this resource.

Returns void
Overrides BaseImageResource.dispose
- Defined in node_modules/@pixi/core/lib/textures/resources/ImageBitmapResource.d.ts:72

`Protected`load

load(): Promise<ImageBitmapResource>
Protected
This can be overridden to start preloading a resource or do any other prepare step.

Returns Promise<ImageBitmapResource>
Handle the validate event
Overrides BaseImageResource.load
- Defined in node_modules/@pixi/core/lib/textures/resources/ImageBitmapResource.d.ts:62

resize

resize(width: number, height: number): void
Trigger a resize event
Parameters
- width: number
  X dimension
- height: number
  Y dimension
Returns void
Inherited from BaseImageResource.resize
- Defined in node_modules/@pixi/core/lib/textures/resources/Resource.d.ts:71

style

style(
    _renderer: Renderer,
    _baseTexture: BaseTexture,
    _glTexture: GLTexture,
): boolean
Set the style, optional to override
Parameters
- _renderer: Renderer
  yeah, renderer!
- _baseTexture: BaseTexture
  the texture
- _glTexture: GLTexture
  texture instance for this webgl context
Returns boolean
- true is success

- baseTexture: BaseTexture
  Parent texture
Returns void
Inherited from BaseImageResource.unbind
- Defined in node_modules/@pixi/core/lib/textures/resources/Resource.d.ts:65

update

update(): void
Checks if source width/height was changed, resize can cause extra baseTexture update. Triggers one update in any case.
