Demo

New Crop Section Style

We add a white mask for crop section area. And we change the resize button to be a circle and make it larger.

Compress Image In Local Browser

We add new props compress. Props compress means the quality of the image you want to compress via browser and then send the compressed image to the server. It is more friendly to mobile devices for saving your network traffic.

Code Example

<ReactCoreImageUpload  
 text=”Upload Your Image”
 className=”btn btn-primary”
 inputOfFile=”files”
 compress={50}
 data={{name: ‘你的名字’}}
 url=”api/upload.php”
 imageUploaded={this.imageUploded}>
 </ReactCoreImageUpload>

Demo

Multiple Files

Set props multiple equal true, and you could select more than one file. And your server will receive an array of files. multiple-size is a number which limits your count of the files you selected.

<ReactCoreImageUpload  
 className=”btn btn-primary”
 imageUploaded={this.imageUploded}
 maxFileSize={5242880}
 multiple={true}
 multipleSize={4}
 url=”/api/upload2.php” >
 </ReactCoreImageUpload>

Crop Image Via Canvas

We are also excited about supporting this feature. crop="local" The Browser will crop the image via canvas API and send the cropped image to the server. You will see HTTP form data like this:

Code example

<ReactCoreImageUpload  
 className=”btn btn-primary”
 imageUploaded={this.crpoServerImageUploaded}
 maxFileSize={5242880}
 crop=”server”
 url=”/api/crop.php” >
 </ReactCoreImageUpload>
