vuejs-clipper

Vue.js image clipping components using Vue-Rx.

• Touch devices supported and fully responsive.

Notice

Before using the plugin & components, here's something you should know :

• It's based on vue-rx.
• Use vuejs-clipper plugin also add vue-rx plugin to vue.
• Components are responsive base on width instead of height, see Component Layout.
• You can clip your own images (local uploaded images or images served on your site), but you cannot clip a cross-origin image unless the image server set the CORS headers.
• Components' input is an image URL, output is a canvas element, they only help you clip images to canvas, you need to handle other things like transform file input to image URL or transform output canvas to image by yourself.
