|
|
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"`, `"2x3"`, `"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.
