function Leadtools.Annotations.Core.AnnCodecs.SaveAsync( file , container , format , savePageNumber )
If file is not a new file, then it must contain valid LEADTOOLS Annotations data previously saved with SaveAsync and this method will insert or replace the page specified in savePageNumber and returns the updated data.
If file is a new file, then this method will create the new LEADTOOLS Annotations data and saves it.
If the value of savePageNumber is 0, the page number to use when saving is obtained from the PageNumber property of container, otherwise, the page number to use when saving is savePageNumber.
LEADTOOLS supported saving multiple contains in the same file each with a unique page number. You can use LoadAsync with a page number to load the desired page.
The SerializeOptions property can contain optional options and events to use during saving of annotations data.
