    <div class="tdesign-demo-image-viewer__base">
      <t-image-viewer :images="[img]">
        <template #trigger="{ open }">
          <div class="tdesign-demo-image-viewer__ui-image">
            <img alt="test" :src="img" class="tdesign-demo-image-viewer__ui-image--img" />
            <div class="tdesign-demo-image-viewer__ui-image--hover" @click="open">
              <span><BrowseIcon size="1.4em" /> 预览</span>
            </div>
          </div>
        </template>
      </t-image-viewer>
    </div>
  </div>
</template>
<script lang="ts" setup>
import { BrowseIcon } from 'tdesign-icons-vue-next';
const img = 'https://tdesign.gtimg.com/demo/demo-image-1.png';
</script>
<style scoped>
.tdesign-demo-image-viewer__ui-image {
  width: 100%;
  height: 100%;
  display: inline-flex;
  position: relative;
  justify-content: center;
  align-items: center;
  border-radius: var(--td-radius-small);
  overflow: hidden;
}

.tdesign-demo-image-viewer__ui-image--hover {
  width: 100%;
  height: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  position: absolute;
  left: 0;
  top: 0;
  opacity: 0;
  background-color: rgba(0, 0, 0, 0.6);
  color: var(--td-text-color-anti);
  line-height: 22px;
  transition: 0.2s;
}

.tdesign-demo-image-viewer__ui-image:hover .tdesign-demo-image-viewer__ui-image--hover {
  opacity: 1;
  cursor: pointer;
}

.tdesign-demo-image-viewer__ui-image--img {
  width: auto;
  height: auto;
  max-width: 100%;
  max-height: 100%;
  cursor: pointer;
  position: absolute;
}

.tdesign-demo-image-viewer__ui-image--footer {
  padding: 0 16px;
  height: 56px;
  width: 100%;
  line-height: 56px;
  font-size: 16px;
  position: absolute;
  bottom: 0;
  color: var(--td-text-color-anti);
  background-image: linear-gradient(0deg, rgba(0, 0, 0, 0.4) 0%, rgba(0, 0, 0, 0) 100%);
  display: flex;
  box-sizing: border-box;
}

.tdesign-demo-image-viewer__ui-image--title {
  flex: 1;
}

.tdesign-demo-popup__reference {
  margin-left: 16px;
}

.tdesign-demo-image-viewer__ui-image--icons .tdesign-demo-icon {
  cursor: pointer;
}

.tdesign-demo-image-viewer__base {
  width: 160px;
  height: 160px;
  margin: 10px;
  border: 4px solid var(--td-bg-color-secondarycontainer);
  border-radius: var(--td-radius-medium);
}
</style>

官方的代码是这样的因为t-design 出来的比较新用的人少

他这个图片预览需要把样式页粘贴下来

我这个是实际应用了已经
