SaveStamp(RasterImage,Stream) Method






The Leadtools.RasterImage object that contain the thumbnail (stamp) image.
A System.IO.Stream containing the data of an existing image file.
Saves a stamp in an existing stream with default options. .NET support Silverlight support
Syntax
public void SaveStamp( 
   RasterImage image,
   Stream stream
)
'Declaration
 
Public Overloads Sub SaveStamp( _
   ByVal image As RasterImage, _
   ByVal stream As Stream _
) 
'Usage
 
Dim instance As RasterCodecs
Dim image As RasterImage
Dim stream As Stream
 
instance.SaveStamp(image, stream)
public void SaveStamp( 
   RasterImage image,
   Stream stream
)
 function Leadtools.Codecs.RasterCodecs.SaveStamp(RasterImage,Stream)( 
   image ,
   stream 
)
public:
void SaveStamp( 
   RasterImage^ image,
   Stream^ stream
) 

Parameters

image
The Leadtools.RasterImage object that contain the thumbnail (stamp) image.
stream
A System.IO.Stream containing the data of an existing image file.
Remarks

The stamp will be written to last page in the file. If that page already has a stamp, it will be overwritten; If the file to which the stamp is being written does not exist, an exception will occur.

This method works for regular JPEG files and Exif JPEG files. For regular JPEG files, the stamp saved is always uncompressed and can be 8 or 24 bits per pixel. The stamp can be any width and height, but the stamp data and stamp header must completely fit in an APP0 marker. Therefore, the size must be less than 64k bytes (0xFFFF).

For Exif JPEG files, the stamps can be uncompressed or JPEG compressed and must be 24 bits per pixel. Exif JPEG stamps are supposed to be 160 x 120. However, LEADTOOLS can save and read Exif JPEG stamps of other dimensions. The stamp, along with other information such as the TIFF_HEADER, 0th IFD, 1st IFD, etc. must completely fit in an APP1 marker. Therefore, the size must be less than 64k bytes (0xFFFF).

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