Summary

Reads a thumbnail image stored in an image stream.

Syntax

C#
Objective-C
C++
Java
public RasterImage ReadStamp( 
   Stream stream, 
   int pageNumber, 
   CodecsImageInfo info 
) 
- (nullable LTRasterImage *)readStampFromStream:(LTLeadStream *)stream  
                                     pageNumber:(NSInteger)pageNumber  
                                          error:(NSError **)error 
public RasterImage readStamp(ILeadStream stream, int pageNumber) 
public: 
RasterImage^ ReadStamp(  
   Stream^ stream, 
   int pageNumber 
)  
vb[VB Syntax] 
Public Function ReadStamp( 
   ByVal _stream_ As Stream, 
   ByVal _pageNumber_ As Integer, 
   ByVal _info_ As CodecsImageInfo 
) As RasterImage 

Parameters

stream
A Stream 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.

info A CodecsImageInfo object containing information about the image.

Return Value

The RasterImage object that this method loads.

Remarks

Only EXIF, CMP, JPEG, FlashPix and HEIF/HEIC formats support stamps. However, not all files of these formats contain stamps.

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

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