 function Leadtools.Codecs.RasterCodecs.ReadStamp(Stream,Int32)(  
   stream , 
   pageNumber

public: 
Leadtools.RasterImage^ ReadStamp(  
   Stream^ stream, 
   int pageNumber

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.

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 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.
