ProMosaic steps of 64 down to 1 px with 120 ms holds, beside a slower 240 ms hold.

Installation

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

Usage

tsx

import { PixelateReveal } from "@/components/ui/chatcn/pro/pixelate-reveal"

<PixelateReveal src={image.url} alt={image.prompt} />

Canvas 2D with smoothing off. Each step divides the frame into whole blocks and samples exactly the object-fit: cover crop, so the last step lines up with the real image pixel for pixel and the swap is invisible. The default duration is 120 ms per step; pass duration for slower holds.

Examples

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 pixelate 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 120 per step, so 720 for the six default steps
`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
`steps`	`number[]`	Block sizes in CSS px, coarse to fine, ending at 1. Default `[64, 32, 16, 8, 4, 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

Six hard cuts, one per step. Nothing blends, scales or moves.
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.
