   stream ,
   pageNumber 
)

public:
RasterCollection<RasterTagMetadata^>^ ReadTags( 
   Stream^ stream,
   int pageNumber
) 

Parameters

stream

A System.IO.Stream containing the input image data.

pageNumber

1-based index of the page from which to read the tags.

Return Value

To read a specific tag stored in a file, use ReadTag(String,Int32,Int32) and to enumerate all the tag ids (but not the data) stored in a file use EnumTags(String,Int32).

This method will throw an exception if the file format does not support tags. To determine whether a file format supports tags, use TagsSupported. You can also automatically load all the tags stored in a file during a load operation by setting the CodecsLoadOptions.Tags property to true. The tags data will be stored in the resulting image RasterImage.Tags collection.

To load all the tags stored in a disk file, use ReadTags(String,Int32).

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
