<script>
import { ImageLoader, Button, InlineLoading } from "carbon-components-svelte";
import Preview from "../../components/Preview.svelte";
let key = 0;
</script>
This utility component uses the [Image API](https://developer.mozilla.org/en-US/docs/Web/API/HTMLImageElement/Image) to programmatically load an image with slottable loading and error states.
### Default
<ImageLoader src="https://upload.wikimedia.org/wikipedia/commons/5/51/IBM_logo.svg" />
### Slots
Use the "loading" and "error" named slots to render an element when the image is loading or has an error.
<ImageLoader src="https://upload.wikimedia.org/wikipedia/commons/5/51/IBM_logo.svg">
<svelte:fragment slot="loading">
<InlineLoading />
</svelte:fragment>
<svelte:fragment slot="error">
An error occurred.
</svelte:fragment>
</ImageLoader>
### With aspect ratio
If `ratio` is set, this component uses the [AspectRatio](/components/AspectRatio) to constrain the image.
Supported aspect ratios include `"2x1"`, `"16x9"`, `"4x3"`, `"1x1"`, `"3x4"`, `"3x2"`, `"9x16"` and `"1x2"`.
<ImageLoader ratio="16x9" src="https://upload.wikimedia.org/wikipedia/commons/5/51/IBM_logo.svg" />
### Fade in
Set `fadeIn` to `true` to fade in the image if successfully loaded.
<Button kind="ghost" on:click="{() => { key++;}}">Reload image</Button>
{#key key}<ImageLoader fadeIn ratio="16x9" src="https://upload.wikimedia.org/wikipedia/commons/5/51/IBM_logo.svg" />{/key}
### Programmatic usage
In this example, a component reference is obtained to programmatically trigger the `loadImage` method.
