) As Leadtools.RasterImage 
public Leadtools.RasterImage ReadStamp(  
   string fileName,

) 
- (nullable LTRasterImage *)readStampFromFile:(NSString *)file  
                                   pageNumber:(NSInteger)pageNumber

 function Leadtools.Codecs.RasterCodecs.ReadStamp(String,Int32)(  
   fileName , 
   pageNumber  
) 
public: 
Leadtools.RasterImage^ ReadStamp(  
   String^ fileName, 
   int pageNumber 
)

Parameters

fileName
A String containing the name of the file which contains the stamp image to load.

pageNumber
1-based index of the page from which the stamp image should be loaded.

codecsimageinfo A CodecsImageInfo object containing information about the image.

Return Value

The 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.

Both ReadStamp(String,Int32) and ReadStamp(String,Int32,CodecsImageInfo) read a thumbnail image from a string and load it into the specified image. The difference is that ReadStamp(String,Int32,CodecsImageInfo) takes a CodecsImageInfo object in order to improve performance.

To create a thumbnail image from any file, use ReadThumbnail.

NOTE: At this time, there are no multi-page formats that support stamps.
