    builder.Writeln("Lorem ipsum dolor sit amet, consectetur adipiscing elit, " +
                    "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.");

// Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
// to modify how that method converts the document to .PDF.
PdfSaveOptions options = new PdfSaveOptions();

// Set the "TextCompression" property to "PdfTextCompression.None" to not apply any
// compression to text when we save the document to PDF.
// Set the "TextCompression" property to "PdfTextCompression.Flate" to apply ZIP compression
// to text when we save the document to PDF. The larger the document, the bigger the impact that this will have.
