public IAsyncOperation<RasterImage> ReadStampAsync( 
   ILeadStream stream,
   int pageNumber
)

'Declaration
 
Public Function ReadStampAsync( _
   ByVal stream As ILeadStream, _
   ByVal pageNumber As Integer _
) As IAsyncOperation(Of RasterImage)

'Usage
 
Dim instance As RasterCodecs
Dim stream As ILeadStream
Dim pageNumber As Integer
Dim value As IAsyncOperation(Of RasterImage)
 
value = instance.ReadStampAsync(stream, pageNumber)

public IAsyncOperation<RasterImage> ReadStampAsync( 
   ILeadStream stream,
   int pageNumber
)

 function Leadtools.Codecs.RasterCodecs.ReadStampAsync( 
   stream ,
   pageNumber 
)

public:
IAsyncOperation<RasterImage^>^ ReadStampAsync( 
   ILeadStream^ stream,
   int pageNumber
)

Parameters

stream: A Leadtools.ILeadStream containing the image data which contains the stamp image to load.
pageNumber: 1-based index of the page from which the stamp image should be loaded.

Return Value

When this method completes, it returns the Leadtools.RasterImage object that this method loads.

Remarks

Only EXIF, CMP, JFIF and FlashPix formats support stamps. However, not all file of these formats contain stamps. To create a thumbnail image from any file, use ReadThumbnail(String,CodecsThumbnailOptions,Int32).

Example

For an example, refer to SaveStamp(RasterImage,String,Int32,Int32,Int32,CodecsSavePageMode).
