ProTiles arriving in random, Bayer, diagonal or center out order.

Installation

$ pnpm dlx shadcn@latest add @chatcn-pro/tile-reveal

Usage

tsx

import { TileReveal } from "@/components/ui/chatcn/pro/tile-reveal"

<TileReveal src={image.url} alt={image.prompt} order="bayer" seed={index} progress={job.progress} />

Each tile settles from a hair smaller than its cell, so the grid reads while it fills and closes seamlessly at the end. Give each image in a grid its own seed so the four never arrive in lockstep. rows mirrors in right to left.

Examples

Generation grid

Four jobs report on their own schedule; each image tiles in with its own seed.

ProA 2 x 2 generation where four jobs report on their own schedule and each image tiles in with its own seed.

States

Waiting for the image, running at 40%, running with no numbers, held by revealed={false}, revealed, a missing file, a timer and right to left.

ProEvery state of the tile reveal.

Props

Prop	Type	Notes
`src`, `alt`	`string`	`alt` is required: the accessible name, announced once the image is in
`progress`	`number \| null`	Real job progress, 0 to 1. `null` means running with no numbers. Leave it out for timer mode
`revealed`	`boolean`	Timer mode: `false` holds the first frame, `true` plays once the image loads. Default `true`
`duration`	`number`	Timer length in ms. Default 1400
`onRevealed`	`() => void`	Once per image, when the plain image shows
`onStatusChange`	`(status: "loading" \| "ready" \| "revealing" \| "revealed" \| "error") => void`
`aspectRatio`, `width`, `height`		Set the frame before the image loads, so nothing shifts
`paper`	`string`	The ground under the effect. Token or CSS color. Default `var(--chatcn-bg)`
`announcement`	`string \| false`	What the live region says once revealed. Default `Image ready: <alt>`
`errorText`, `retryLabel`		Copy for the error state and its reload button
`columns`	`number`	Tiles across. Default 8
`rows`	`number`	Tiles down. Defaults to the count that keeps tiles closest to square
`order`	`"random" \| "bayer" \| "rows" \| "diagonal" \| "center"`	Default `random`
`seed`	`number`	Default 1
`maxPixels`	`number`	Default 1.5 MP

Keyboard

Key	Action
`Tab`	Reaches the Reload image button in the error state. The reveal itself takes no focus

Accessibility

The effect layer is aria-hidden. The real <img> with your alt is always there, and the frame is aria-busy until the reveal ends.
A polite live region says Image ready: <alt> once, when the plain image shows. Progress ticks are never announced.
Under forced-colors: active the effect hides and the plain image shows with system colors.
A broken file shows what happened and a Reload image button that retries the download.

Motion

Each tile fades in over 22% of the run from scale 0.94 inside its own cell. Opacity and scale only.
Under reduced motion one still frame holds while the job runs, then the image crossfades in over 200 ms. Nothing moves.
The timer only runs on screen in a visible tab; offscreen it waits where it was.
