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.
