vue-annotator

Create annotation using SVG and HTML element.

Usage

For complete example see src/stories/*/*.vue

<v-annotator inertia
  :drawing="enableDrawingMode"
  @select="openDialog"
  :minSize="[50, 50]"
  :grid="[5, 5]"
  :multipleSelect="keyIsDown.Ctrl"
>

    <img draggable="false" src="background.png" />

    <rect slot="annotation" stroke="green" x="300" y="150" width="170" height="100" />
    <polygon slot="annotation" stroke="purple" points="200,10 250,190 160,210" />

    <rect slot="drawing" stroke="red" />

</v-annotator>

<style scoped>
@import '~vue-annotator/style.css';

/* Your beloved style */
</style>

Enable --skipLibCheck if using typescript

Due to taye/interact.js#623

In tsconfig.json

{
  compilerOptions: {
    skipLibCheck: true
  }
}

Now it should work fine

import { Vue, Component } from 'vue-property-decorator'
import VAnnotator from 'vue-annotator'

@Component({ components: { VAnnotator } })
export class MyCanvas extends Vue {
  /** Your beloved logic */
}
