GetTotalPagesAsync Method

public IAsyncOperation<int> GetTotalPagesAsync( 
   ILeadStream stream
)

'Declaration
 

Public Function GetTotalPagesAsync( _
   ByVal stream As ILeadStream _
) As IAsyncOperation(Of Integer)

'Usage
 

Dim instance As RasterCodecs
Dim stream As ILeadStream
Dim value As IAsyncOperation(Of Integer)
 
value = instance.GetTotalPagesAsync(stream)

public IAsyncOperation<int> GetTotalPagesAsync( 
   ILeadStream stream
)

- (void)totalPagesInStreamAsync:(LTLeadStream *)stream 
                     completion:(void (^)(NSInteger totalPages, NSError * __nullable error))completion
            

 function Leadtools.Codecs.RasterCodecs.GetTotalPagesAsync( 
   stream 
)

public:
IAsyncOperation<int>^ GetTotalPagesAsync( 
   ILeadStream^ stream
) 

Parameters

stream

A ILeadStream containing the image data to query.

Return Value

GetInformationAsync and GetFormatAsync use GetInformationAsync internally. So, if more information about the image is required, it is recommended to call GetInformationAsync directly and obtain the data once.

For an example, refer to Load(Stream stream, int pageNumber).
