ImageLoader

A loader for loading an Image. This is used internally by the CubeTextureLoader and TextureLoader.

Code Example


    // instantiate a loader
    const loader = new v3d.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.');
        }
    );
