Class: BaseTexture

PIXI.BaseTexture

A Texture stores the information that represents an image. All textures have a base texture, which contains information about the source. Therefore you can have many textures all using a single BaseTexture

Methods

PIXI.BaseTexture.addToCache (baseTexture, id) void static

Adds a BaseTexture to the global BaseTextureCache. This cache is shared across the whole PIXI object.

Name Type Description
baseTexture PIXI.BaseTexture

The BaseTexture to add to the cache.

id string

The id that the BaseTexture will be stored against.

PIXI.BaseTexture.from (source, options, strict) PIXI.BaseTexture static

Helper function that creates a base texture based on the source you provide. The source can be - image url, image element, canvas element. If the source is an image url or an image element and not in the base texture cache, it will be created and loaded.

Name Type Attributes Default Description
source string | Array<string> | HTMLImageElement | HTMLCanvasElement | SVGElement | HTMLVideoElement

The source to create base texture from.

options IBaseTextureOptions<RO> <optional>

See PIXI.BaseTexture's constructor for options.

options.pixiIdPrefix string <optional>
pixiid

If a source has no id, this is the prefix of the generated id

strict boolean <optional>

Enforce strict-mode, see PIXI.settings.STRICT_TEXTURE_CACHE.

Returns:
Type Description
PIXI.BaseTexture The new base texture.

PIXI.BaseTexture.fromBuffer (buffer, width, height, options) PIXI.BaseTexture<PIXI.BufferResource> static

Create a new BaseTexture with a BufferResource from a Float32Array. RGBA values are floats from 0 to 1.

PIXI.BaseTexture

destroy () void

Destroys this base texture. The method stops if resource doesn't want this texture to be destroyed. Removes texture from all caches.

dispose () void

Frees the texture 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.
