Package Exports

react-medium-image-zoom

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-medium-image-zoom) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-medium-image-zoom

This library is a different implementation of Medium.com's image zoom that allows for a low-res and high-res images to work together for "zooming" effects, works regardless of parent elements that have overflow: hidden and is made to work explicitly with React.js >= v0.14.

You can view the demo here.

Installation

$ npm install --save react-medium-image-zoom

Usage

import ImageZoom from 'react-medium-image-zoom'

function MyComponent(props) {
  return (
    <div>
      <p>Some text...</p>

      <ImageZoom
        image={{
          src: 'bridge.jpg',
          alt: 'Golden Gate Bridge',
          className: 'img',
          style: { width: '50em' }
        }}
        zoomImage={{
          src: 'bridge-big.jpg',
          alt: 'Golden Gate Bridge'

      />

      <p>Some text...</p>

Prop	Type	Required	Default	Details
`image`	object	yes	none	The original image
`zoomImage`	object	no	`image`	The image to be used for zooming
`zoomMargin`	number	no	`40`	Pixel number to offset zoomed image from the window
`isZoomed`	boolean	no	`false`	For more direct control over the zoom state
`shouldReplaceImage`	boolean	no	`true`	Once the image has been "zoomed" and downloaded the larger image, this replaces the original `image` with the `zoomImage`
`shouldRespectMaxDimension`	boolean	no	`false`	When true, don't make the zoomed image's dimensions larger than the original dimensions. Currently only supported when NO zoomImage is provided.
`defaultStyles`	object	no	`{}`	For fine-grained control over all default styles (`zoomContainer`, `overlay`, `image`, `zoomImage`)
`shouldHandleZoom`	func	no	`(event) => true`	Pass this callback to intercept a zoom click event and determine whether or not to zoom. Function must return a truthy or falsy value

Each one of these image props accepts normal image props, for example:

Prop	Type	Required	Details
`src`	string	yes	The source for the image
`alt`	string	no	The alt text for the image
`className`	string	no	Classes to apply to the image
`style`	object	no	Additional styles to apply to the image
...	...	no	...
