ReadStamp(Stream,int,CodecsImageInfo) Method

Summary

Reads a thumbnail image stored in an image stream.

Syntax

Objective-C

C++/CLI

Java

Python

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 
)

def ReadStamp(self,stream,pageNumber,info):

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, HEIF/HEIC, and PNG 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.
