export default {
mounted() {
// Upon mounting of the component, we accessed the .bind({...})
// function to put an initial image on the canvas.
this.$refs.croppieRef.bind({
url: 'http://i.imgur.com/Fq2DMeH.jpg',
})
},
data() {
return {
cropped: null,
images: [
'http://i.imgur.com/fHNtPXX.jpg',

methods: {
bind() {
// Randomize cat photos, nothing special here.
let url = this.images[Math.floor(Math.random() * 4)]
// Just like what we did with .bind({...}) on
// the mounted() function above.
this.$refs.croppieRef.bind({
url: url,
});
},
// CALBACK USAGE
crop() {
// Here we are getting the result via callback function
// and set the result to this.cropped which is being

let options = {
format: 'jpeg',
circle: true
}
this.$refs.croppieRef.result(options, (output) => {
this.cropped = output;
});
},

cropViaEvent() {
this.$refs.croppieRef.result(options);
},
result(output) {
this.cropped = output;
},
update(val) {
console.log(val);

// Rotates the image
this.$refs.croppieRef.rotate(rotationAngle);
}

File Upload Sample
You can upload file instead of using direct image link.
Usage
In your form add a file input
along with vue-croppie
component.
<template>
<input type="file" @change="croppie"/>
<vue-croppie ref="croppieRef" :enableOrientation="true" :boundary="{ width: 450, height: 300}" :viewport="{ width:400, height:250, 'type':'square' }">
</vue-croppie>
<!-- the result -->
<img :src="cropped">
<button @click="crop">Crop</button>
</template>
<script>
export default {
data() {
return {
croppieImage: '',
cropped: null
};
},
methods: {
croppie (e) {
var files = e.target.files || e.dataTransfer.files;
if (!files.length) return;
var reader = new FileReader();
reader.onload = e => {
this.$refs.croppieRef.bind({
url: e.target.result
});
};
reader.readAsDataURL(files[0]);
},
crop() {
// Options can be updated.
// Current option will return a base64 version of the uploaded image with a size of 600px X 450px.
let options = {
type: 'base64',
size: { width: 600, height: 450 },
format: 'jpeg'
};
this.$refs.croppieRef.result(options, output => {
this.cropped = this.croppieImage = output;
console.log(this.croppieImage);
});
}
}
};
Using Options
All Croppie options were converted to props to be able use them in the vue-croppie
component.
Usage
<vue-croppie
ref=croppieRef
:enableOrientation="true"
:mouseWheelZoom="false"
:viewport="{ width: 200, height: 200, type: 'circle' }"
@result="fn"
>
</vue-croppie>
API
All of the properties and methods are based on Croppie documentation. All property and method names are "==="
the same if you know what I mean.
Except for these few things below.
Option | Type | Default | Description |

ref (required) | Object | none | ref is used to create a reference to the child component, in order to have access to it's methods and properties. Specific example is to access the result() function of vue-croppie from outside the component. |
resultType | String | base64 | The image encoding of the cropped image via result() . Also available in Croppie Documentation. |
customClass | String | none | You can pass a custom class or classes to the props customClass like customClass="class1 class2 class3" |

. See here
FAQ
How to clear/destroy coppie?
I added a new method called refresh()
and can be used as this.$refs.croppieRef.refresh()
, but the croppie instance is now being refreshed automatically after every crop()
invocation.
