如何在 iTextPDF 中设置基于 x 和 y 位置的对齐方式。

PdfPCell cell;

请查看这个示例...

public static void Main() {


        // step 1: creation of a document-object
        Document document = new Document();


        try {


            // step 2:
            // we create a writer that listens to the document
            // and directs a PDF-stream to a file
            PdfWriter writer = PdfWriter.getInstance(document, new FileStream("Chap1002.pdf", FileMode.Create));


            // step 3: we open the document
            document.Open();


            // step 4: we grab the ContentByte and do some stuff with it
            PdfContentByte cb = writer.DirectContent;


            // we tell the ContentByte we're ready to draw text
            cb.beginText();


            // we draw some text on a certain position
            cb.setTextMatrix(100, 400);
            cb.showText("Text at position 100,400.");


            // we tell the contentByte, we've finished drawing text
            cb.endText();
        }
        catch(DocumentException de) {
            Console.Error.WriteLine(de.Message);
        }
        catch(IOException ioe) {
            Console.Error.WriteLine(ioe.Message);
        }


        // step 5: we close the document
        document.Close();
    }
}
