- A loader for loading an [page:Image]. This is used internally by the
- [page:CubeTextureLoader], [page:ObjectLoader] and [page:TextureLoader].
- </p>
- <h2>Code Example</h2>
- <code>
- // instantiate a loader
- const loader = new THREE.ImageLoader();
- // load a image resource
- loader.load(
- // resource URL
- 'textures/skyboxsun25degtest.png',
- // onLoad callback
- function ( image ) {
- // use the image, e.g. draw part of it on a canvas
- const canvas = document.createElement( 'canvas' );
- const context = canvas.getContext( '2d' );
- context.drawImage( image, 100, 100 );
- },
- // onProgress callback currently not supported
- undefined,
- // onError callback
- function () {
- console.error( 'An error happened.' );
- }
- );
- </code>
- <p>
- Please note three.js r84 dropped support for ImageLoader progress events.
- For an ImageLoader that supports progress events, see
