Aspose.Pdf使用教程:设置PDF文件信息
Aspose.Pdf允许你设置PDF文件的特定信息,比如作者、创建日期、主题和标题等。进行着些信息设置,您需要创建一个DocumentInfo对象并单独设置这些属性的值。一旦这些属性值完成设置,你就仅仅需要使用文档对象的save方法保存更新后的文档。
下面是使用Aspose.Pdf设置PDF文件信息的示例代码
C#
//open document Document pdfDocument = new Document("input.pdf"); //specify document information DocumentInfo docInfo = new DocumentInfo(pdfDocument); docInfo.Author ="Aspose"; docInfo.CreationDate =DateTime.Now; docInfo.Keywords ="Aspose.Pdf, DOM, API"; docInfo.ModDate =DateTime.Now; docInfo.Subject ="PDF Information"; docInfo.Title ="Setting PDF Document Information"; //save output document pdfDocument.Save("output.pdf");
VB.NET
'open document Dim pdfDocument As New Document("input.pdf") 'specify document information Dim docInfo As New DocumentInfo(pdfDocument) docInfo.Author = "Aspose" docInfo.CreationDate = DateTime.Now docInfo.Keywords = "Aspose.Pdf, DOM, API" docInfo.ModDate = DateTime.Now docInfo.Subject = "PDF Information" docInfo.Title = "Setting PDF Document Information" 'save output document pdfDocument.Save("output.pdf")
