Buat PDF menggunakan C#

// Create a new PDF document
PdfDocument pdfDocument = new PdfDocument();
// Create an empty page
PdfPage pdfPage = pdfDocument.AddPage();
// Get an XGraphics object for drawing
XGraphics xGraphics = XGraphics.FromPdfPage(pdfPage);
// Create a font
XFont xFont = new XFont("Verdana", 20, XFontStyle.BoldItalic);
// Draw the text
xGraphics.DrawString("File Format Developer Guide", xFont, XBrushes.Black,
    new XRect(0, 0, pdfPage.Width, pdfPage.Height),
    XStringFormats.Center);
// Save the document...
pdfDocument.Save("fileformat.pdf");
    

Buat Anotasi Teks PDF melalui C#

 // Create a PDF text annotation
PdfTextAnnotation textAnnot = new PdfTextAnnotation();
textAnnot.Title = "This is the title";
textAnnot.Subject = "This is the subject";
textAnnot.Contents = "This is the contents of the annotation.\rThis is the 2nd line.";
textAnnot.Icon = PdfTextAnnotationIcon.Note;
gfx.DrawString("The first text annotation", font, XBrushes.Black, 30, 50, XStringFormats.Default);
// Convert rectangle from world space to page space. This is necessary because the annotation is
// placed relative to the bottom left corner of the page with units measured in point.
XRect rect = gfx.Transformer.WorldToDefaultPage(new XRect(new XPoint(30, 60), new XSize(30, 30)));
textAnnot.Rectangle = new PdfRectangle(rect);
// Add the annotation to the page
page.Annotations.Add(textAnnot);

Gabungkan Dokumen melalui Java

 // Open the input files
PdfDocument inputDocument1 = PdfReader.Open(filename1, PdfDocumentOpenMode.Import);
PdfDocument inputDocument2 = PdfReader.Open(filename2, PdfDocumentOpenMode.Import);
// Create the output document
PdfDocument outputDocument = new PdfDocument();
// Show consecutive pages facing. Requires Acrobat 5 or higher.
outputDocument.PageLayout = PdfPageLayout.TwoColumnLeft;
XFont font = new XFont("Verdana", 10, XFontStyle.Bold);

format.Alignment = XStringAlignment.Center;
format.LineAlignment = XLineAlignment.Far;
XGraphics gfx;
XRect box;
int count = Math.Max(inputDocument1.PageCount, inputDocument2.PageCount);
for (int idx = 0; idx < count; idx++)
{
// Get page from 1st document
PdfPage page1 = inputDocument1.PageCount > idx ?
inputDocument1.Pages[idx] : new PdfPage();
// Get page from 2nd document
PdfPage page2 = inputDocument2.PageCount > idx ?
