Hi,

Thanks for using Aspose.Cells.

The embedded image "图片 5" is emf dual file. In Emf only records, it is a black background, but in Emf Plus records, it is a transparent black background. We only support parse Emf only records now. We are now trying to support parse emf plus records, if we have any news for you, we will update you asap.
