A React.JS Image Cropper with touch support for React v0.15
This project has been forked from https://github.com/jerryshew/react-image-cropper, v1.1.2 and includes some changes that jerryshew did not wanted to merge. See this repo also for React versions >0.15.
See the original repository for a demo of the image cropper - https://github.com/jerryshew/react-image-cropper
Our custom changes Custom:
- limit the cropper container height to a max value (useful for portait images (e.g. 9:21), that would cause the cropper to stretch a lot)
- define max crop sizes that cause the cropper to limit the resulting image to some maximum values
-
import {Cropper} from 'react-image-cropper' -
styles are all inline
-
define Cropper with src, and ref to execute crop method
<Cropper src="http://braavos.me/images/posts/college-rock/the-smiths.png" ref="cropper"/>
- crop and get image url
image.src = this.refs.cropper.crop()
- get crop values
OPTIONS (optional):
- maxHeight : make sure the cropped image is not bigger than this max height
- maxWidth : make sure the cropped image is not bigger than this max width
image.src = this.refs.cropper.crop(maxWidth, maxHeight)
var values = this.refs.cropper.values()
- onChange for preview
(values) => onChange(values)
