Summary

Extracts all XMP metadata from the source file and saves it to the destination XML file.

Syntax

C++

public void ExtractXMPMetadata( 
   string sourceFileName, 
   string destFileName 
)

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

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.

Remarks

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.
