      </ScreenFit>
    <div class="action">
      <span class="action-text">适配模式：</span>
      <button id="cover" @click="action(EFillType.cover)">cover</button>
      <button id="widthFit" @click="action(EFillType.widthFit)">widthFit</button>
      <button id="heightFit" @click="action(EFillType.heightFit)">heightFit</button>

适配方式

提供了5中适配方式，分别为EFillType枚举中的cover、widthFit、heightFit、contain、fill、

• cover 等比缩放，占满整个容器
• widthFit 宽度占满容器，高等比缩放
• heightFit 高度占满容器，宽等比缩放
• contain 宽或高等比缩放，满足最大占满容器 默认
• fill 宽和高填充整个容器，不进行等比缩放

本项目是对screen-fit的vue封装，props支持screen-fit所有的配置
