[QUESTION]previewImage图片显示补全怎么办

[xmsz]

上下两边被裁掉了

因为img的外层的样式

.__universal_preview_image_item {
    max-height: 70%;
    display: flex;
    justify-content: center;
    align-items: center;
    flex-shrink: 0;
    width: 100%;
    position: relative;
    transition-property: transform;
    overflow: hidden;
}

最大高度是70%
