react-viewer-mda

react image viewer.

Introduction

Because i can`t comfortable use viewerjs in react, so i create react-viewer to replace it. This is a fork of react-viewer.

v2.2.5

• Added downloadable option to image download.
• Hide navigation arrows when shows only one image.

v2.2.6

• Added afterChange property.
• Disable apropriate keyboard shortcuts when zoomable and rotatable is set to false.

Installation

npm install react-viewer-mda --save

Usage

import * as React from 'react';
import Viewer from 'react-viewer-mda';
import 'react-viewer-mda/dist/index.css';

class App extends React.Component<any, any> {
  constructor() {
    super();

    this.state = {
      visible: false,
    };
  }

  render() {
    return (
      <div>
        <button onClick={() => { this.setState({ visible: !this.state.visible }); } }>show</button>
        <Viewer
        visible={this.state.visible}
        onClose={() => { this.setState({ visible: false }); } }
        images={[{src: '', alt: '', name: ''}]}
        />
      </div>
    );
  }
}
