[name]

A loader for loading an [page:Image] as an [link:https://developer.mozilla.org/de/docs/Web/API/ImageBitmap ImageBitmap]. An ImageBitmap provides an asynchronous and resource efficient pathway to prepare textures for rendering in WebGL.

Example

[example:webgl_loader_imagebitmap WebGL / loader / ImageBitmap]


		// instantiate a loader
		var loader = new THREE.ImageBitmapLoader();

		// load a image resource
		loader.load(
			// resource URL
			'textures/skyboxsun25degtest.png',

			// onLoad callback
			function ( imageBitmap ) {
				var texture = new THREE.CanvasTexture( imageBitmap );
				var material = new THREE.MeshBasicMaterial( { map: texture } );
			},

			// onProgress callback currently not supported
			undefined,

			// onError callback
			function ( err ) {
				console.log( 'An error happened' );
			}
		);

Constructor

[name]( [param:LoadingManager manager] )

[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].

Creates a new [name].

Properties

[property:LoadingManager manager]

The [page:LoadingManager loadingManager] the loader is using. Default is [page:DefaultLoadingManager].

[property:String options]

An optional object that sets options for the internally used [link:https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/createImageBitmap createImageBitmap] factory method. Default is *undefined*.

[property:String path]

The base path from which files will be loaded. See [page:.setPath]. Default is *undefined*.

Methods

[method:null load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )

[page:String url] — the path or URL to the file. This can also be a [link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].
[page:Function onLoad] — Will be called when load completes. The argument will be the loaded [page:Image image].
[page:Function onProgress] — Will be called while load progresses. The argument will be the progress event.
[page:Function onError] — Will be called when load errors.

Begin loading from url and return the [page:ImageBitmap image] object that will contain the data.

[method:ImageBitmapLoader setCrossOrigin]()

This method exists for compatibility reasons and implements no logic. It ensures that [name] has a similar interface like [page:ImageLoader].

[method:ImageBitmapLoader setOptions]( [param:Object options] )

Sets the options object for [link:https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/createImageBitmap createImageBitmap].

[method:ImageBitmapLoader setPath]( [param:String path] )

Sets the base path or URL from which to load files. This can be useful if you are loading many images from the same directory.
