The XMP packet node name in the prefix:local format.
Namespace : DevExpress.Pdf.Xmp
Assembly : DevExpress.Pdf.v25.2.Core.dll
NuGet Package : DevExpress.Pdf.Core
public class XmpName :
IEquatable<XmpName>
Public Class XmpName
Implements IEquatable(Of XmpName)
The following members return XmpName objects:
When you add a new node to the packet, use the XmpName object to specify the node name. Call the XmpName.Get(String, String) method to generate a node name and register the prefix.
The code sample below sues the XmpName.Get(String, String) method to generate a name for a new structure node:
using DevExpress.Pdf;
using DevExpress.Pdf.Xmp;
//...
using (PdfDocumentProcessor pdfDocumentProcessor = new PdfDocumentProcessor())
{
// Load a document
pdfDocumentProcessor.LoadDocument("Documents//Invoice.pdf");
PdfDocument document = pdfDocumentProcessor.Document;
// Retrieve metadata:
XmpDocument metadata = XmpDocument.FromString(document.Metadata.Data);
// Add MaxPageSize structure:
XmpName structureName = XmpName.Get("MaxPageSize", "http://ns.adobe.com/xap/1.0/t/pg/");
XmpStructure dimensions = metadata.CreateStructure(structureName);
metadata.RegisterNamespace("http://ns.adobe.com/xap/1.0/sType/Dimensions#", "stDim");
dimensions.Add("stDim:h", 11);
dimensions.Add("stDim:w", 8.5f);
dimensions.Add("stDim:Unit", "inch");
// Embed modified metadata in the document:
document.SetMetadata(metadata);
// Save the result:
pdfDocumentProcessor.SaveDocument("Invoice_Upd.pdf");
}
