// Create a new PDF document:
var doc = new GcPdfDocument();
// While normally the PDF Version written into the document is determined automatically
// (as the minimal version needed for the features actually used in this document),
// it can be explicitly set:
doc.PdfVersion = "1.7";
// By default, GcPdfDocument uses CompressionLevel.Fastest to reduce the file size.
// Setting the level to CompressionLevel.NoCompression will result in uncompressed PDF:
doc.CompressionLevel = CompressionLevel.NoCompression;
// By default, font subsets containing just the glyphs used in the document,
// are embedded. This can be changed to embed whole fonts (which may result in
// huge file size) or to not embed fonts as we do here (embedding can also
// be controlled for individual fonts using the GcPdfDocument.Fonts collection):
doc.FontEmbedMode = FontEmbedMode.NotEmbed;
// Document properties such as title, author etc. can be set on GcPdfDocument.DocumentInfo,
// but it should be noted that similar properties can be set in the GcPdfDocument.Metadata
// and in most PDF readers properties set in metadata (see below) take precedence.
// Here we set some of the properties available in DocumentInfo:
doc.DocumentInfo.Title = "DsPdf Document Info Sample";
doc.DocumentInfo.Author = "Jaime Smith";
doc.DocumentInfo.Subject = "GcPdfDocument.DocumentInfo";
doc.DocumentInfo.Producer = "DsPdfWeb Producer";
doc.DocumentInfo.Creator = "DsPdfWeb Creator";
// For sample sake, set CreationDate to a date 10 years in the future:
doc.DocumentInfo.CreationDate = Common.Util.TimeNow().AddYears(10);
// Document metadata is available via the GcPdfDocument.Metadata property.
// It provides a number of predefined accessors, such as:
doc.Metadata.Contributors.Add("contributor 1");
doc.Metadata.Contributors.Add("contributor 2");
doc.Metadata.Contributors.Add("contributor 3");
doc.Metadata.Copyright = "MESCIUS inc.";
doc.Metadata.Creators.Add("Creator 1");
doc.Metadata.Creators.Add("Creator 2");
doc.Metadata.Creators.Add("Creator 3");
doc.Metadata.Description = "Sample document description";
doc.Metadata.Keywords.Add("Keyword1");
doc.Metadata.Keywords.Add("MESCIUS");
doc.Metadata.Keywords.Add("Keyword3");
doc.Metadata.Source = "Sourced by DsPdfWeb";
// Arbitrary metadata can also be added using the AddProperty method:
doc.Metadata.AddProperty("http://purl.org/dc/elements/1.1/", "language", "English");
// Finally, add a page and some text to the document and save it:
Common.Util.AddNote("DsPdf Document Properties sample.", doc.NewPage());
// Done:
doc.Save(stream);
return doc.Pages.Count;
