1.先去下載插件github 下載 https://github.com/Kujiale-Mobile/Painter 下載好了把painter整個文件放在components里面

index.json

{
  "usingComponents": {
    "painter":"/components/painter/painter"
  }
}

index.wxml

<button open-type="getUserInfo" bindgetuserinfo="getUserInfo"> 獲取頭像昵稱 </button>
<button bind:tap='createPoster'>生成海報</button>
<image class="poster" src="{{imgURL}}" mode="cover"></image>
<painter 
	wx-if="{{showPainter}}"
    palette="{{template}}"
    bind:imgOK="onImgOK" 
    />

index.js

Page({
  data: {
    template: {},
    imgURL:'',
	showPainter:false,
	avatarUrl:''
  },
  createPoster(){
    this.getPattle()
  },
  onImgOK(e) {
    console.log("onImgOK")
    console.log(e.detail.path)
    this.setData({
      imgURL: e.detail.path
    })
  },
  getPattle(){
	  let _this = this
	  _this.setData({
	    template: {
	      width:"750rpx",
	      height:"1624rpx",
	      views:[
	         {
	            type: 'image',
