Remarks

This method replaces the metadata associated with a document loaded from the source image with the provided metadata and saves the updated image to the destination stream. This method does not replace the metadata assotiated with individual pages. This method does not change the actual pixel data. The structure of the provided metadata tree should correspond to the metadata tree from the source image. This method does not save any metadata tags provided in the metadata tree that are not supported by the source image format. See ImageGear.Core.ImGearMetadataNode for more details about the ImageGear metadata.

This method is only supported for PDF, PS and DICOM file formats.
