				<div class="class-description"><p>A loader for loading images as an <a href="https://developer.mozilla.org/en-US/docs/Web/API/ImageBitmap" target="_blank" rel="noopener">ImageBitmap</a>.
An <code>ImageBitmap</code> provides an asynchronous and resource efficient pathway to prepare
textures for rendering.</p>
<p>Note that <a href="Texture.html#flipY">Texture#flipY</a> and <a href="Texture.html#premultiplyAlpha">Texture#premultiplyAlpha</a> are ignored with image bitmaps.
They needs these configuration on bitmap creation unlike regular images need them on uploading to GPU.</p>
<p>You need to set the equivalent options via <a href="ImageBitmapLoader.html#setOptions">ImageBitmapLoader#setOptions</a> instead.</p>
<p>Also note that unlike <a href="FileLoader.html">FileLoader</a>, this loader avoids multiple concurrent requests to the same URL only if <code>Cache</code> is enabled.</p></div>
				<h2>Code Example</h2>
				<div translate="no"><pre><code class="language-js">const loader = new THREE.ImageBitmapLoader();
loader.setOptions( { imageOrientation: 'flipY' } ); // set options if needed
const imageBitmap = await loader.loadAsync( 'image.png' );
const texture = new THREE.Texture( imageBitmap );
texture.needsUpdate = true;
</code></pre></div>
