Parameters

stream
A System.IO.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

A Leadtools.RasterCommentMetadata object containing the comment field information. If no such comment is found in the file, this method will return a null reference (Nothing in Visual Basic).
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 Leadtools.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 ReadComments(String,Int32).

Example
For an example, refer to ReadComment(String,Int32,RasterCommentMetadataType).
