Set page margins with iTextSharp

Question

I have a template PDF file that has aa PDF form field embedded in. I am using PdfStamper to fill out these fields. In addition, I would like to be able to change the margins for generated PDF. is there any way I can modify the page margins on the stamped PDF?

Answer 1

你可以在一行中完成所有这些工作。

Document doc = new Document(PageSize.LETTER, 0f, 0f, 0f, 0f );

Answer 2

Only way I know of is like this.

iTextSharp.text.Rectangle rec = new iTextSharp.text.Rectangle(pageWidth, pageHeight); 
Document doc = new Document(rec); 
doc.SetMargins(0f, 0f, 0f, 0f);

However, this will limit margins too

Answer 3

setMaring Impelemented as

    public override bool SetMargins(float marginLeft, float marginRight, float marginTop, float marginBottom)
            {
                if ((this.writer != null) && this.writer.IsPaused())
                {
                    return false;
                }
                this.nextMarginLeft = marginLeft;
                this.nextMarginRight = marginRight;
                this.nextMarginTop = marginTop;
                this.nextMarginBottom = marginBottom;
                return true;
            }

therefor margin applied for next page. for solve this problem after open pdfDocument call newPage() this solution work for empty pdfDocument .

    using (FileStream msReport = new FileStream(pdfPath, FileMode.Create))
            {
                using (Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f))
                {
                    try
                    {
                        //open the stream 
                        pdfDoc.Open();
                        pdfDoc.setMargin(20f, 20f, 20f, 20f);
                        pdfDoc.NewPage();

                        pdfDoc.Close();

                    }
                    catch (Exception ex)
                    {
                        //handle exception
                    }

                    finally
                    {


                    }

                }

            }
