WriteTagsAsync(ILeadStream,Int32,RasterTagMetadata[]) Method
Summary
Writes or changes one or more tags to an existing stream.
Syntax
public IAsyncAction WriteTagsAsync(ILeadStream stream,int pageNumber,Leadtools.RasterTagMetadata[] tags)
Public Overloads Function WriteTagsAsync( _ByVal stream As ILeadStream, _ByVal pageNumber As Integer, _ByVal tags() As Leadtools.RasterTagMetadata _) As IAsyncAction
public IAsyncAction WriteTagsAsync(ILeadStream stream,int pageNumber,Leadtools.RasterTagMetadata[] tags)
function Leadtools.Codecs.RasterCodecs.WriteTagsAsync(ILeadStream,Int32,RasterTagMetadata[])(stream ,pageNumber ,tags)
public:IAsyncAction^ WriteTagsAsync(ILeadStream^ stream,int pageNumber,Leadtools.array<RasterTagMetadata^>^ tags)
Parameters
stream
A ILeadStream that contains the file data.
pageNumber
1-based index of the page at which to write the tag.
tags
An array of RasterTagMetadata objects to identify the data in the TIFF file.
Remarks
This method writes tags into an existing file or changes tags in an existing file.
This method works only with TIFF files.
Note: Use this method carefully. LEADTOOLS will not restrict the tags that you write. If you write bad tags, the file might become corrupted. Consult the TIFF documentation for a list of predefined tags. It is recommended that you write only the user-defined tags (the tags between 0x8000 and 0xFFFF).
See the TIFF documentation for a complete list of the TIFF tags and types.
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.
