   ILeadStream stream, 
   int pageNumber,

   ILeadStream^ stream, 
   int pageNumber, 
   Leadtools.RasterCommentMetadataType type 
)

Parameters

stream
A stream containing the input file data.

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

type
The type of comment. Refer to Types of File Comments.

Return Value

An asynchronous delete operation on a RasterCodecs object.

Remarks

Some file formats can contain comments, and some cannot, and each file format has its own set of comment types. When you save a file, the comments in the RasterImage object can be saved in the file. The index into the array (specified using a constant) determines the type of comment.

You can use CommentsSupported to determine whether a certain file format supports tags.

To read all the comments stored in a file, use ReadCommentsAsync.
