这些操作有效:

  • HEIC 为其他格式,例如转换 IMG_8293.HEIC c.jpg

这些操作产生无效输出:

  • 将任何格式转换为 HEIC,例如:convert c.jpg c.heic
  • 旋转 HEIC:转换 IMG_8293.HEIC -rotate 90 IMG_8293.HEIC
  • 其他 HEIC 操作,例如触发器、触发器等。

无效输出意味着:元数据​​正确显示但 MacOS 预览抱怨:“ The file “c.heic” could not be opened. It may be damaged or use a file format that Preview doesn’t recognise.”。
