		<h1>[name]</h1>

		<p class="desc">A loader for loading a `.tga` resource. <br />
		[link:https://en.wikipedia.org/wiki/Truevision_TGA TGA] is a raster graphics, image file format.
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { TGALoader } from 'three/addons/loaders/TGALoader.js';
		</code>

		<h2>Code Example</h2>

		<code>
		// instantiate a loader
		const loader = new TGALoader();

		// load a resource
		const texture = loader.load(
			// resource URL
			'textures/crate_grey8.tga'
			// called when loading is completed
			function ( texture ) {

				console.log( 'Texture is loaded' );

			},
			// called when the loading is in progresses
			function ( xhr ) {

				console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

			},
			// called when the loading fails
			function ( error ) {

				console.log( 'An error happened' );

			}
		);

		const material = new THREE.MeshPhongMaterial( {
			color: 0xffffff,
			map: texture
		} );
		</code>

		<h2>Constructor</h2>

		<h3>[name]( [param:LoadingManager manager] )</h3>
		<p>
		[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].
		</p>
		<p>
		Creates a new [name].
		</p>

		<h2>Properties</h2>
		<p>See the base [page:Loader] class for common properties.</p>

		<h2>Methods</h2>
		<p>See the base [page:Loader] class for common methods.</p>

		<h3>[method:DataTexture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
		<p>
		[page:String url] — A string containing the path/URL of the `.tga` file. <br />
		[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives loaded [page:DataTexture] as an argument.<br />
		[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains .[page:Integer total] and .[page:Integer loaded] bytes. If the server does not set the Content-Length header; .[page:Integer total] will be 0.<br />
		[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
		</p>
		<p>
		Begin loading from url and pass the loaded [page:DataTexture texture] to onLoad. The [page:DataTexture texture] is also directly returned for immediate use (but may not be fully loaded).
