   int savePageNumber

public IAsyncAction SaveAsync(  
   StorageFile file, 
   Leadtools.Annotations.Core.AnnContainer container, 
   Leadtools.Annotations.Core.AnnFormat format, 
   int savePageNumber 
)

 function Leadtools.Annotations.Core.AnnCodecs.SaveAsync(  
   file , 
   container , 
   format , 
   savePageNumber  
)

Parameters

file
Destination Windows Runtime StorageFile object to save the data to.

container
The AnnContainer to be saved. This value must not be null.

format
Must be AnnFormat.Annotations.

savePageNumber
Page number to put inside the data.

Return Value

A IAsyncAction of the operation.

Remarks

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 containers 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.
