)

'Declaration

Public Overloads Sub ExtractXMPMetadata( _
   ByVal sourceFileName As String, _
   ByVal destFileName As String _
)

'Usage

Dim instance As RasterCodecs
Dim sourceFileName As String
Dim destFileName As String
 
instance.ExtractXMPMetadata(sourceFileName, destFileName)

public void ExtractXMPMetadata( 
   string sourceFileName,
   string destFileName
)

 function Leadtools.Codecs.RasterCodecs.ExtractXMPMetadata(String,String)( 
   sourceFileName ,
   destFileName 
)

public:
void ExtractXMPMetadata( 
   String^ sourceFileName,
   String^ destFileName
)

Parameters

sourceFileName: A String containing the source image file from which the metadata should be read.
destFileName: A String containing the destination filename to which the metadata should be written in XML format.

The file referenced by sourceFileName must be a file format that supports XMP. For example PNG, PDF, JPEG, TIFF and SVG.

To determine if a file format supports XMP, use MetadataItemsSupported.
