WriteCommentsAsync(ILeadStream,Int32,IVectorView<RasterCommentMetadata>) Method

Show in webframe







A Leadtools.ILeadStream containing the input file data.
1-based index of the page at which to write the comment.
A collection of Leadtools.RasterCommentMetadata objects containing the comments data.
Writes one or more comments to an existing stream.
Syntax

   ILeadStream stream,
   int pageNumber,
   IVectorView<RasterCommentMetadata> comments
)
'Declaration
 
Public Overloads Function WriteCommentsAsync( _
   ByVal stream As ILeadStream, _
   ByVal pageNumber As Integer, _

'Usage
 
Dim instance As RasterCodecs
Dim stream As ILeadStream
Dim pageNumber As Integer
Dim comments As IVectorView(Of RasterCommentMetadata)
Dim value As IAsyncAction
 
value = instance.WriteCommentsAsync(stream, pageNumber, comments)

 function Leadtools.Codecs.RasterCodecs.WriteCommentsAsync(ILeadStream,Int32,IVectorView{RasterCommentMetadata})( 
   stream ,
   pageNumber ,
   comments 
)
public:
IAsyncAction^ WriteCommentsAsync( 
   ILeadStream^ stream,
   int pageNumber,
   IVectorView<RasterCommentMetadata^>^ comments

Parameters

stream
A Leadtools.ILeadStream containing the input file data.
pageNumber
1-based index of the page at which to write the comment.
comments
A collection of Leadtools.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 Files topic for more information.

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