Cropper Demo

A controlled square image-cropping example using the Dice UI Cropper components. It initializes crop position and zoom state, displays a remote landscape image, and renders a crop area over the image.

Installation

pnpm dlx shadcn@latest add https://diceui.com/r/radix-vega/cropper-demo.json

Usage

usage.tsx
import * as React from "react";import {  Cropper,  CropperArea,  CropperImage,  type CropperPoint,} from "@/registry/bases/radix/ui/cropper";export default function CropperDemo() {  const [crop, setCrop] = React.useState<CropperPoint>({ x: 0, y: 0 });  const [zoom, setZoom] = React.useState(1);  return (    <Cropper      aspectRatio={1}      crop={crop}      zoom={zoom}      onCropChange={setCrop}      onZoomChange={setZoom}      className="min-h-72"    >      <CropperImage        src="https://images.unsplash.com/photo-1506744038136-46273834b3fb?w=1920&h=1080&fit=crop&auto=format&fm=webp&q=80"        alt="Profile picture"        crossOrigin="anonymous"      />      <CropperArea />    </Cropper>  );}
  • Use as a minimal starting point for profile-picture or avatar cropping.
  • Use when you need a controlled cropper with a fixed 1:1 aspect ratio.
  • Use to demonstrate remote-image cropping with cross-origin loading enabled.
  • Use as a reference for wiring crop and zoom state to the Cropper component.

Examples

Controlled square profile image crop

Uses the same controlled crop and zoom state as the registry example for a profile-picture workflow.

controlled-square-profile-image-crop.tsx
import * as React from "react";import {  Cropper,  CropperArea,  CropperImage,  type CropperPoint,} from "@/registry/bases/radix/ui/cropper";export default function ProfileCropper() {  const [crop, setCrop] = React.useState<CropperPoint>({ x: 0, y: 0 });  const [zoom, setZoom] = React.useState(1);  return (    <Cropper      aspectRatio={1}      crop={crop}      zoom={zoom}      onCropChange={setCrop}      onZoomChange={setZoom}      className="min-h-72"    >      <CropperImage        src="https://images.unsplash.com/photo-1506744038136-46273834b3fb?w=1920&h=1080&fit=crop&auto=format&fm=webp&q=80"        alt="Profile picture"        crossOrigin="anonymous"      />      <CropperArea />    </Cropper>  );}

Portrait cropper with a fixed square frame

Shows the same API with a different image source while preserving the 1:1 crop ratio.

API reference

PropTypeDefaultDescription
propsnull—The registry example's default CropperDemo component does not declare or accept props.

Accessibility

  • Provide a meaningful alt value on CropperImage; this example uses "Profile picture" rather than leaving the image unlabeled.
  • The example does not include separate zoom controls, save actions, or status feedback. Add accessible labeled controls and feedback when exposing those actions in a production workflow.
  • Ensure the crop interaction remains usable with the keyboard or provide an equivalent accessible positioning and zooming interface if the underlying cropper interaction is pointer-only.

Use the "Cropper Demo" component (diceui-radix/cropper-demo) from its shadcn registry.1. Install it with: npx shadcn@latest add https://diceui.com/r/radix-vega/cropper-demo.json2. Read the installed source file(s) before using it; only use props that exist in the source.3. Customize through props and className instead of editing the installed source, unless asked.4.
