Class EmbedFileType

Supported file types for embedding in PDF/A-3 compliant documents. Essential for creating invoice PDFs with structured data attachments.

// Embed invoice XML (ZUGFeRD/Factur-X):
var xmlConfig = new EmbedFileConfiguration(EmbedFileType.xml) {
    EmbedFileName = "invoice_2024.xml"
};
var embedPath = new EmbedFilePath("invoice.xml", xmlConfig);

// Attach source PDF:
var pdfConfig = new EmbedFileConfiguration(EmbedFileType.pdf);

// Include logo image:
var pngConfig = new EmbedFileConfiguration(EmbedFileType.png);

XML for structured invoice data (ZUGFeRD/Factur-X)

Inheritance

Assembly: IronPdf.dll

Syntax

public sealed class EmbedFileType : Enum

The EmbedFileType enumeration in IronPDF declares the MIME class of a payload attached to a PDF/A-3 document.

Part of the IronPdf namespace, members are pdf, png, and xml (3 total). EmbedFileConfiguration reads the value to tag each attachment correctly, which matters for ZUGFeRD invoices where the embedded XML must be discoverable by archival readers.

See add and remove attachments for the embedding workflow.
