# Markup Image with Vue.js (customizable)
[![](https://img.shields.io/npm/dt/vue-image-markup.svg)](https://www.npmjs.com/package/vue-image-markup)
[![](https://img.shields.io/npm/v/vue-image-markup.svg)](https://www.npmjs.com/package/vue-image-markup)

`vue-image-markup` will provide you to edit uploaded image easily and save it.

## Installation

`npm i vue-image-markup`

`yarn add vue-image-markup`

## Usage

First import the Editor component inside 
your Vue component.
```vue
 import Editor from 'vue-image-markup';
```

Then you'll be able to use Editor component.

#### Example:

You must give your editor component ```ref```,which will help you to call the functions to set editor mode,clean objects or undo/redo your changes.
```vue
<Editor :canvasWidth="canvasWidth" :canvasHeight="canvasHeight" ref="editor" editorId="canvasId"/>

mounted() {
    $this.$refs.editor.set(this.editor.mode,this.editor.options);
}

```

`canvasWidth` prop will set editor width

`canvasHeight` prop will set editor height

`ref` with the help of ref, you will control the editor

`editorId (optional)` will set editor id, allowing the use of multiple editors in the same component
## Function set(`type`,`params`)
##### With the set() function you choose editor's mode,which should get two parameters `type` and `params`
Editor have 7 modes
 - text
 - circle
 - rect
 - selectMode
 - arrow
 - freeDrawing
 - crop
 - eraser
 
`params`  parameter must be an object which set the type and every type have it's own options.

#### Text Mode
##### `set('text',params)` to enable text mode in editor,where `params` must be object and has it's default value
```javascript
this.$refs.editor.set('text')
```

-------------       | ------------- | -------------
fill                | `black`    | color
fontFamily          | `Arial`    | font-family
fontSize            | `32`       | font-size
fontWeight          | `100`      | font-weight(`100`,`200`,`300`,`400`,`500`,`600`,`700`,`bold`,`normal`)
fontStyle           | `normal`   | font-style(`normal`,`italic`,`oblique`)
placeholder         | `Add Text` | default text placeholder when the text will be added
id                  |       `''`     | text id
                                               
or you can customize your editor text mode styles by overwriting default values.

 this.$refs.editor.set('text',textModeOptions)

strokeUniform       | `true`         | When `false`, the stoke width will scale with the object. When `true`, the stroke will always match the exact pixel size entered for stroke width
noScaleCache        | `false`         |When `true`, cache does not get updated during scaling. The picture will get block if scaled too much and will be redrawn with correct details at the end of scaling. this setting is performance and application dependant
