Summary
Writes one or more comments to an existing stream.
Syntax
public IAsyncAction WriteCommentsAsync(ILeadStream stream,int pageNumber,Leadtools.RasterCommentMetadata[] comments)
Public Overloads Function WriteCommentsAsync( _ByVal stream As ILeadStream, _ByVal pageNumber As Integer, _ByVal comments() As Leadtools.RasterCommentMetadata _) As IAsyncAction
public IAsyncAction WriteCommentsAsync(ILeadStream stream,int pageNumber,Leadtools.RasterCommentMetadata[] comments)
function Leadtools.Codecs.RasterCodecs.WriteCommentsAsync(ILeadStream,Int32,RasterCommentMetadata[])(stream ,pageNumber ,comments)
public:IAsyncAction^ WriteCommentsAsync(ILeadStream^ stream,int pageNumber,Leadtools.array<RasterCommentMetadata^>^ comments)
Parameters
stream
A ILeadStream containing the input file data.
pageNumber
1-based index of the page at which to write the comment.
comments
An array of RasterCommentMetadata objects containing the comments data.
Remarks
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 topic for more information.
