感谢你的 PR！这个功能的实现可能比表面看起来更复杂，需要注意以下几点：

1. 在 ImagePreview 组件中，图片预览会根据图片的长宽比例以 contain 或 cover 的方式显示。旋转图片时，也应遵循这一规则。仅调整旋转角度可能会导致四周出现黑边，或图片超出可视区域的问题。
2. 使用 matrix 替代 rotate 属性值，同时保留原注释，避免因 Safari 的内部优化问题导致元素不渲染。
3. 新增的 rotate 和 rotateAngle 属性可能显得冗余，考虑是否可以合并为一个属性。

@inottn 您好 按照优化建议调整了下。看是否可行

[inottn]

抱歉回复晚了。我查看了许多相关的应用后，觉得我们可以将旋转行为限定为 90 度，不支持其他角度。暂时没有想到用户需要非 90 度旋转的场景，这样的设计也能让代码更简洁。

@inottn 有道理 已经调整

测试了下，当旋转后双击放大，拖动时的边界似乎有问题。

确实是有这个问题，这次修改 maxMoveX 和 maxMoveY 的计算逻辑，考虑旋转后的尺寸和缩放比例，我试了下应该是正常的
