vue项目中-上传图片头像并裁剪成任意大小的实现
先看效果图：

放大缩小-翻转-查看都有的哦！

直接上代码

<el-dialog title="图片剪裁" :visible.sync="dialogVisible" append-to-body width="30%" :before-close="delCropp">
      <div class="cropper-content">
        <el-row>
          <el-col :xs="24" :md="12" :style="{ height: '150px' }">
            <vueCropper
              ref="cropper"
              :img="option.img"
              :info="false"
              :auto-crop="option.autoCrop"
              :auto-crop-width="option.autoCropWidth"
              :auto-crop-height="option.autoCropHeight"
              :fixed-box="option.fixedBox"
              @realTime="realTime"
              @imgLoad="imgLoad"
            />
          </el-col>
          <el-col :xs="24" :md="12" style="height: 150px">
            <div
              style="
