SaveStamp(RasterImage,string) Method


Saves a stamp in an existing file with default options.

public void SaveStamp( 
   RasterImage image, 
   string fileName 
Public Overloads Sub SaveStamp( _ 
   ByVal image As RasterImage, _ 
   ByVal fileName As String _ 
- (BOOL)saveStamp:(LTRasterImage *)image  
             file:(NSString *)file  
            error:(NSError **)error 
void SaveStamp(  
   RasterImage^ image, 
   String^ fileName 


The RasterImage object that contain the thumbnail (stamp) image.

A String containing the name of an existing image file.


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).


For an example, refer to SaveStamp.
