vue-svg-pan-zoom : Vue 3 component for SVG-Pan-Zoom
This module is a very simple Vue 3 component providing the goodness of SVG-Pan-Zoom for SVG elements.
/!\ WARNING: the module is young, basic, probably will have its API change with no notice, and likely to have bugs. Use at your own risk, send patches for my eternal gratitude.
Basic Use
In a Single File Component:
<template>
<SvgPanZoom
style="width: 500px; height: 500px; border:1px solid black;"
:zoomEnabled="true"
:controlIconsEnabled="true"
:fit="false"
:center="true"
>
<svg>
<circle x="10" y="10" r="5" />
</svg> </SvgPanZoom
>`
</template>
<script>
import SvgPanZoom from "vue-svg-pan-zoom";
export default {
components: { SvgPanZoom }
};
</script>
Notes
Currently the SvgPanZoom
component only works with a svg
child -- embed
won't work.

svgpanzoom object
To access the created svgpanzoom
javascript object, you can
listen to the created
event on the SvgPanZoom
component.
<template>
<div>
<input type="button" value="center me" @click="center" />
<SvgPanZoom
style="width: 500px; height: 500px; border:1px solid black;"
:fit="false"
@created="registerSvgPanZoom"
>
<RawTiger />
</SvgPanZoom>
</div>
</template>
<script>
import RawTiger from "./RawTiger.vue";
import SvgPanZoom from "vue-svg-pan-zoom";
export default {
components: { SvgPanZoom, RawTiger },
data: () => ({ svgpanzoom: null }),
methods: {
registerSvgPanZoom(svgpanzoom) {
this.svgpanzoom = svgpanzoom;
},
center() {
if (!this.svgpanzoom) return;
this.svgpanzoom.center();
}
}
};
</script>
Use with thumbnails
In a Single File Component:
<template>
<SvgPanZoom style="width: 300px; height: 500px; border:1px solid black; ">
<template #default>
<svg>...</svg>
<template>
<template #thumbnail>...</template>
</SvgPanZoom>
</template>
<script>
import SvgPanZoom from "vue-svg-pan-zoom";
export default {
components: { SvgPanZoom }
};
</script>
Just like the main SvgPanZoom
component, the thumbnail
slot needs to
be assigned to a svg
node -- embed
won't work.
Storybook demos
