How to Add Watermark in The Middle Bottom

I'm trying to add a watermark in a pdf file in the center bottom of pdf file .. I tried many ways but i did not figure out how it's works exactly to select the location of watermark.
Anyway here is the code:
string filepath = #"~/Images/logo-01.png";
iTextSharp.text.Image pageIn = iTextSharp.text.Image.GetInstance(Server.MapPath(filepath));
pageIn.Alignment = iTextSharp.text.Image.ALIGN_MIDDLE;
pageIn.ScaleToFit(150, 150);
pageIn.Alignment = iTextSharp.text.Image.UNDERLYING;
pageIn.SetAbsolutePosition((PageSize.A4.Width - pageIn.ScaledWidth) / 2, (PageSize.A4.Height - pageIn.ScaledHeight) / 10);
Again i want to make the watermark position in the max center bottom of the page.

You may try using GroupDocs.Watermark for .NET that allows controlling the horizontal and vertical position of the watermark in the documents. This is how you can add watermark at the bottom of the pages in a PDF document:
using (PdfDocument doc = Document.Load<PdfDocument>("D:\\sample.pdf"))
{
// Add text watermark
TextWatermark watermark = new TextWatermark("Protected Document", new Font("Arial", 8));
watermark.HorizontalAlignment = HorizontalAlignment.Center;
watermark.VerticalAlignment = VerticalAlignment.Bottom;
doc.AddWatermark(watermark);
// Add image watermark
ImageWatermark imageWatermark = new ImageWatermark("D:\\watermark.png");
imageWatermark.HorizontalAlignment = HorizontalAlignment.Center;
imageWatermark.VerticalAlignment = VerticalAlignment.Bottom;
doc.AddWatermark(imageWatermark);
// Save document
doc.Save("D:\\output.pdf");
}

Custom Headers and footers for novacode DocX

I'm trying to create a docx document that has header and footer for all pages.
For the header i want the image to ocuppy all of the header. Like the image below:
For the footer i want it to be on the left and at the right i want to have the number of the page. Like the image below:
what i have right now is:
using (var docx = DocX.Create(filename))
{
docx.AddHeaders();
docx.AddFooters();
var headerDefault = docx.Headers.odd;
var footerDefault = docx.Footers.odd;
Novacode.Paragraph hp = headerDefault.InsertParagraph();
Novacode.Paragraph fp = footerDefault.InsertParagraph();
Novacode.Image logoHeader = docx.AddImage(System.Web.HttpContext.Current.Server.MapPath("/Images/jpg/header_pdf.jpg"));
Novacode.Image logoFooter = docx.AddImage(System.Web.HttpContext.Current.Server.MapPath("/Images/jpg/footer_pdf.jpg"));
hp.AppendPicture(logoHeader.CreatePicture());
fp.AppendPicture(logoFooter.CreatePicture());
The problem is that both the header and the footer get the margins of the rest of the document and even if i do
docx.MarginTop = 0F;
docx.MarginRight = 0F;
docx.MarginBottom = 0F;
docx.MarginLeft = 0F;
there will still be a top margin on the header and a bottom margin on the footer.
Does anyone have a solution? thanks

Late answer, but maybe it would be useful for someone - I faced the same problem. The problem is here:
Novacode.Paragraph hp = headerDefault.InsertParagraph();
Novacode.Paragraph fp = footerDefault.InsertParagraph();
Header and footer already have paragraph, you should just get it:
Novacode.Paragraph hp = headerDefault.Paragraphs.First();
So the margins appeared because there were two paragraphs, one of them was empty but had new line symbol.

How do you change the icon size of a PDF sticky note placed via iTextSharp?

I'm trying to enlarge the icon of a PDF sticky note. Here's an image showing the sticky icon that I've stamped on the first page of the PDF for context:
I was under the impression the icon was guided by a rectangle that could be manipulated. Here's my code that has not been effective yet:
using (PdfStamper stamp = new PdfStamper(reader, fs))
{
PdfWriter attachment = stamp.Writer;
foreach (string file in files_to_attach)
{
PdfFileSpecification pdfAttch = PdfFileSpecification.FileEmbedded(attachment, file, file, null);
stamp.AddFileAttachment(file, pdfAttch);
}
//Create Note for first page
Rectangle rect = new Rectangle(850, 850, 650, 650);
PdfAnnotation annotation = PdfAnnotation.CreateText(stamp.Writer, rect, "TITLE OF NOTE", "Body text of the note", false, "Comment");
//Enlarge the Sticky Note icon
PdfDictionary page = reader.GetPageN(1);
PdfArray annots = page.GetAsArray(PdfName.ANNOTS);
PdfDictionary sticky = annots.GetAsDict(0);
PdfArray stickyRect = sticky.GetAsArray(PdfName.RECT);
PdfRectangle stickyRectangle = new PdfRectangle(
stickyRect.GetAsNumber(0).FloatValue - 50, stickyRect.GetAsNumber(1).FloatValue - 20,
stickyRect.GetAsNumber(2).FloatValue, stickyRect.GetAsNumber(3).FloatValue - 30);
sticky.Put(PdfName.RECT, stickyRectangle);
//Apply the Note to the first page
stamp.AddAnnotation(annotation, 1);
stamp.Close();
}
I thought I could change the float values and that would change the shape of the icon but so far it has not effected it all. Thank you for any suggestions.

You can't. The icon that is displayed for the "Comment" annotation is supplied by the viewer. The rect property is only used to define the lower left corner of where the icon gets placed on the page by the viewer. According to the PDF specification for annotations with the type "Text", "Conforming readers shall provide predefined icon appearances for at least the following standard names: Comment, Key, Note, Help, NewParagraph, Paragraph, Insert.
You can, however, create your own image, of any size, and use it as the appearance for a "Stamp" annotation. It can even look exactly like a "Comment" icon, just bigger. It would end up functioning in the same way for the end user.

Setting image position using iTextSharp

I have a problem with regards on the page orientation of the paper size.
I have a pdf file which contains portrait and landscape page.
this code works perfectly.
string FileLocation = "c:\\Temp\\SomeFile.pdf";
string WatermarkLocation = "c:\\Temp\\watermark.gif";
Document document = new Document();
PdfReader pdfReader = new PdfReader(FileLocation);
PdfStamper stamp = new PdfStamper(pdfReader, new FileStream(FileLocation.Replace(".pdf","[temp][file].pdf"), FileMode.Create));
iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(WatermarkLocation);
img.SetAbsolutePosition(250,300); // set the position in the document where you want the watermark to appear (0,0 = bottom left corner of the page)
PdfContentByte waterMark;
for (int page = 1; page <= pdfReader.NumberOfPages; page++)
{
waterMark = stamp.GetUnderContent(page);
waterMark.AddImage(img);
}
stamp.FormFlattening = true;
stamp.Close();
// now delete the original file and rename the temp file to the original file
File.Delete(FileLocation);
File.Move(FileLocation.Replace(".pdf", "[temp][file].pdf"), FileLocation);
since I'm using absolute value to set the image position.
img.SetAbsolutePosition(250,300);
How can T set the image position if the page is landscape or portrait?
note: One pdf with landscape and portrait page orientation.
Is there by chance that I can use if statement?
if (//paper is landscape)
{
//code here
}
else
{
//code here
}

What do you want to achieve?
Normally, iText takes into account the value of the page rotation. This means that when a page is rotated, the coordinates will be rotated too.
If you want to overrule this, you can add this line:
stamper.RotateContents = false;
This is explained in Chapter 6 of my book. You can try this example to see the difference:
No rotation, text added normally: hello1.pdf
Rotation, text added normally ( = rotated): hello2.pdf
Rotation, text added with rotation ignored: hello3.pdf
Of course, this assumes that a rotation was defined for the pages. Sometimes, landscape is mimicked by defining a different page size instead of defining a rotation.
In that case, you should also read Chapter 6 because it explains how to get the MediaBox of a document. see the example PageInformation that introduces methods such as GetPageSize(), GetRotation() and GetPageSizeWithRotation().
This is all documented, but if it doesn't answer your question, please clarify. As demonstrated in the example, the rotation is taken into account by default when adding new content, so maybe I misunderstood the question.

Adding different sized pages to PDF using iTextSharp

I have a table and a chart to be added to a PDF Document. I have used the iTextSharpLibrary to add the contents to the PDF file.
Actually the problem is that the chart has a width of 1500px and the table fits in comfortably in an A4 page size.
Actually the chart image that I get must not be scaled to fit in the page as it reduces the viewability. Hence, I need to add a new page that has a wider width than the other ones or at least change the page orientation to landscape and then add the image. How do I do this?
This is the code that I used to add a new page and then resize the page and then add the image. This is not working. Any fixes?
var imageBytes = ImageGenerator.GetimageBytes(ImageSourceId);
var myImage = iTextSharp.text.Image.GetInstance(imageBytes);
document.NewPage();
document.SetPageSize(new Rectangle(myImage.Width, myImage.Height));
myImage.ScaleToFit(document.PageSize.Width, document.PageSize.Height);
document.Add(myImage);

I fixed the Issue. I have to set the page size before calling the GetInstance of the Pdfdocument. Then, i can give different pagesizes for each page

I'm not sure what you mean by before calling the GetInstance of the Pdfdocument, but setting the pageSize right before calling newPage works.
Here follows the c# code to create a new pdf that's made of two pictures, no matter how wild their sizes difference is. The important lines here are the new Document and SetPageSize ones.
static public void MakePdfFrom2Pictures (String pic1InPath, String pic2InPath, String pdfOutPath)
{
using (FileStream pic1In = new FileStream (pic1InPath, FileMode.Open))
using (FileStream pic2In = new FileStream (pic2InPath, FileMode.Open))
using (FileStream pdfOut = new FileStream (pdfOutPath, FileMode.Create))
{
//Load first picture
Image image1 = Image.GetInstance (pic1In);
//I set the position in the image, not during the AddImage call
image1.SetAbsolutePosition (0, 0);
//Load second picture
Image image2 = Image.GetInstance (pic2In);
// ...
image2.SetAbsolutePosition (0, 0);
//Create a document whose first page has image1's size.
//Image IS a Rectangle, no need for new Rectangle (Image.Width, Image.Height).
Document document = new Document (image1);
//Assign writer
PdfWriter writer = PdfWriter.GetInstance (document, pdfOut);
//Allow writing
document.Open ();
//Get writing head
PdfContentByte pdfcb = writer.DirectContent;
//Put the first image on the first page
pdfcb.AddImage (image1);
//The new page will have image2's size
document.SetPageSize (image2);
//Add the new second page, and start writing in it
document.NewPage ();
//Put the second image on the second page
pdfcb.AddImage (image2);
//Finish the writing
document.Close ();
}
}
