WriteCommentAsync Method
Summary
Writes a comment to an existing stream.
Syntax
public IAsyncAction WriteCommentAsync(ILeadStream stream,int pageNumber,Leadtools.RasterCommentMetadata comment)
Public Function WriteCommentAsync( _ByVal stream As ILeadStream, _ByVal pageNumber As Integer, _ByVal comment As Leadtools.RasterCommentMetadata _) As IAsyncAction
public IAsyncAction WriteCommentAsync(ILeadStream stream,int pageNumber,Leadtools.RasterCommentMetadata comment)
function Leadtools.Codecs.RasterCodecs.WriteCommentAsync(stream ,pageNumber ,comment)
public:IAsyncAction^ WriteCommentAsync(ILeadStream^ stream,int pageNumber,Leadtools.RasterCommentMetadata^ comment)
Parameters
stream
A ILeadStream that contains the file data.
pageNumber
1-based index of the page at which to write the comment.
comment
A RasterCommentMetadata object containing the comment data.
Remarks
An asynchronous write operation on a RasterCodecs object. This function only applies to TIF, uncompressed EXIF, or FPX files.
When you add or remove tags, the tags array at the end of the file is re-written. When you modify existing tags, the new tag value is added to the file and the IFD is modified as necessary. In all of these cases, there is no image recompression.
Some restrictions apply to this function if you use an IFD to indicate to which page to write the comment. See the Loading and Saving Large TIFF / BigTIFF Files and Types of File Comments topics for more information.
