Indicates whether this PDF document has any embedded files (attachments).
public bool HasEmbeddedFiles {get;}
public boolean hasEmbeddedFiles();
public:
property bool HasEmbeddedFiles

bool get()
}
HasEmbeddedFiles # get (PDFDocument)
true if the PDF document has embedded files; otherwise, false.
IsPortfolio and HasEmbeddedFiles are automatically populated by the PDFDocument constructor.
If the value of HasEmbeddedFiles is true, then this PDF file has one or more embedded files (attachments). The properties of these files can be obtained using ParseDocumentStructure with PDFParseDocumentStructureOptions.EmbeddedFiles. When this method returns the values of EmbeddedFiles and EmbeddedFilesSchemas will be populated.
