Image — Kuito Dokumentation

Display a bundled, remote or local-file image. Use it for avatars, covers and photos returned by the picker or camera.

Load a cover without a blank flash

tsx

import { Image } from 'kuito';

export default function Cover() {
  return (
    <Image
      src="https://example.com/cover.jpg"
      width={160}
      aspectRatio={1}
      borderRadius={8}
      placeholder="#1e293b"
      fadeDuration={250}
    />
  );
}

Behavior

Give the image dimensions or an aspect ratio so layout can reserve space before download. placeholder fills the waiting area and fadeDuration controls its reveal. Remote images use native caching; image.prefetch warms the cache.

Props

Prop	Meaning
`src`	A URL string, `{ uri, headers? }`, or an imported image (assets).
`objectFit`	CSS's `object-fit`: `cover` (default), `contain`, `fill` or `none`.
`tintColor`	Recolors opaque pixels, for icons.
`onLoadStart` / `onLoadEnd`	Around every load, success or failure.
`onLoad`	`{ width, height }` of the image in pixels.
`onError`	`{ error }`, e.g. `"HTTP 404"`.
`aspectRatio` (Kuito)	Width ÷ height: sizes the view before the image arrives.
`placeholder` (Kuito)	Color shown while loading.
`thumbhash` (Kuito)	A base64 ThumbHash: its blurred preview shows while loading, over `placeholder`.
`fadeDuration` (Kuito)	Cross-fade in milliseconds when the image appears; 0 by default.
`cache` (Kuito)	`memory-disk` (default), `memory`, `disk` or `none`.

`aria-hidden`	`Prop<boolean>`	Nein	Screen readers skip the view and its subtree.

`transition`	`Partial<Record<"opacity" \| "backgroundColor" \| "transform" \| "borderRadius" \| "borderColor" \| "shadow" \| "width" \| "height" \| "all", Animation<unknown> \| AnimationSpec>>`	Nein	How the animatable props move when they change, enter or leave, by group; a CSS `transition` compiles to it.
`animate`	`Partial<Record<AnimatableProps, string \| number>>`	Nein	Animatable props whose every change moves as `transition` says; the first value applies at once.
`enter`	`Effect`	Nein	Where the view enters from: `fade.and(slide.up(12))`.
`exit`	`Prop<Effect>`	Nein	Where the view leaves to; it stays on screen until it is there. The renderer gets `true`, and keeps the view until `exited`.
`layout`	`Animation<number>`	Nein	How the view moves to a new frame the layout gives it: `layout={spring()}`.
`borderRadius`	`Animatable<number>`	Nein	—
`overflow`	`Prop<"visible" \| "hidden" \| "clip" \| "scroll">`	Nein	hidden and scroll clip; as in CSS, either lets a flex item shrink below its content.

`shadowRadius`	`Animatable<number>`	Nein	—

`sharedId`	`Prop<string>`	Nein	A view the navigation stack flies to the view with the same sharedId on the screen it pushes or pops to (docs/navigation.md#shared-elements).
`src`	`Prop<ImageSource>`	Nein	A URL, or a bundled image as its import gives it.
`objectFit`	`Prop<"none" \| "cover" \| "contain" \| "fill">`	Nein	CSS's `object-fit`: `cover` fills and crops, `contain` fits, `fill` distorts, `none` keeps its size, centered.
`placeholder`	`Prop<string>`	Nein	Color shown while the image loads.
`fadeDuration`	`Prop<number>`	Nein	Cross-fade duration in milliseconds when the image appears; 0 by default.
`tintColor`	`Prop<string>`	Nein	Recolors the image's opaque pixels, for icons.
`cache`	`Prop<"none" \| "memory-disk" \| "memory" \| "disk">`	Nein	Which caches may serve and keep the image; `memory-disk` by default.
