Hi ,
I cannot figure out how to add an invisible signature to an existing PDF.

My test code:

var pdfIn = "C:\\Prg\\Test\\TestTelerikPDF\\pdf\\demo.pdf";
var pdfSigned = $"{pdfIn}.sign.pdf";
var pfx = "C:\\Prg\\Test\\TestTelerikPDF\\pdf\\Cert.pfx";

using (var input = new FileStream(pdfIn, FileMode.Open, FileAccess.Read))
{
    var document = new PdfFormatProvider().Import(input);

    var certificate = new X509Certificate2(pfx, "passs");
    var signatureField = new SignatureField("Blabla");
    signatureField.Signature = new Signature(certificate);

    document.AcroForm.FormFields.Add(signatureField);

    var settings = new PdfExportSettings();
    settings.ComplianceLevel = PdfComplianceLevel.PdfA3B;

    var formatProvider = new PdfFormatProvider();
    formatProvider.ExportSettings = settings;

    using (var ms = new FileStream(pdfSigned, FileMode.Create))
        formatProvider.Export(document, ms);
}

This code create an output PDF but the signature is missing :-(

Can you help me please?

Hi,

some of those are briefly mentioned in the docs, others have been subject in previous requests in this forum. Nevertheless, I could not succeed doing these things. It is really hard to describe what i want properly, but i try my best:

- I want the content to take more space of the A4 page, means i want to crop away some of the white space of the top, right, bottom and left to make more room for the content.

- I want a table to take up 100% of the page's height and then in one column have one text block to be positioned at the top and another text block at the bottom. Similar to using flexbox in css and have it "justify-content: space-between", see the "text block" elements in the attached jpeg

- I need page numbers on each page. This was requested a number of times, but it seems like it was still not implemented. Is this correct? What is the best way to do this in 2023? see the numbers at the bottom in the jpeg

- I want to add a repeating page header to each page. see the Repeating Heading element in the jpeg

I created a rough layout design, which is attached as jpeg. Imagine the layout to be a table with currently one row and two columns.

I also took the current c# code and attached it.

I want to import pdf document to a RadFlowWordDocument in the current Run from code.

Is it possible? I have imported pdf using RadEditor.

Basically i am trivarsing whole word document template and updating the text of merge field run.
But after updating the text i want to delete the merge field. How to do that?

var currentDocument = document.EnumerateChildrenOfType<DocumentElementBase>().ToList();
                    int indexElement = 0;
                    foreach (var currentElement in currentDocument)
                    { 

if (currentElement.GetType() == typeof(Run))
                        {
                            currentRun = (Run)currentElement;

 if (currentRun.Text.StartsWith("«") && currentRun.Text.Length > 2)
                            {

string runText= currentRun.Text.Substring(1, currentRun.Text.Length - 2);
if(runText == "name")
currentRun.Text = "faraz";

}

Now after updating the text i want to delete the merge field and maintain the run text. How to do that?

I'm using RadFlowDocument editor to insert a document in a specific position after a text from run.

So flow is read a document runs and when a text is reach insert another RawFlowDocument in it.

But the problem is always adding it in the end.

I want to insert it at specific position. 

There are total 3 documents that needs to be added at specific position.
The run text shows i am at the right position but the generated document always shows new document in the end.

I'm using RadFlowDocument to edit a document (docx), this file is a combination of different docx file.

I have to add Table of content in this file. I saw this code but it is using RadDocument instead of RadFlowDocument class

RadDocument document = new RadDocument();
RadDocumentEditor editor = new RadDocumentEditor(new RadDocument());
editor.InsertField(new TableOfContentsField(), FieldDisplayMode.Result);

How can I add ToC using RadFlowDocument ?

Thanks

I am trying to generate a PDF document but don't know how to control the Page size. As the printout is most likely A4, I would like to print it horizontally in order to fit my table in. The following is my code snippet. The first few rows of the table are the header.

Hi, i'm trying to use document processing to convert HTML template to PDF, but fonts are missing from resulting file, maybe even from the imported html.

How can I find out if the fonts are already missing after importing HTML?

What is the best way to convert HTML to PDF keeping images, fonts, etc. using document processing?

This is one of my attempts to get it to work.

static void Main(string[] args)
        {
            string templateFileName = @"html template.htm";
            string pdfPath = @"test html template to pdf.pdf";
            FileStream templateAsStream = new FileStream(templateFileName, FileMode.Open, FileAccess.Read);

            ///////////
            //telerik
            ///////////

            

            try
            {               
                // Register the font 
                byte[] fontDataR = File.ReadAllBytes("Raleway-VariableFont_wght.ttf");
                System.Windows.Media.FontFamily fontFamilyR = new System.Windows.Media.FontFamily("Releway");
                byte[] fontDataRL = File.ReadAllBytes("Raleway-Light.ttf");
                System.Windows.Media.FontFamily fontFamilyRL = new System.Windows.Media.FontFamily("Releway Light");

                //Telerik.Windows.Documents.Fixed.Model.Fonts.
                FontsRepository.RegisterFont(fontFamilyR, System.Windows.FontStyles.Normal, System.Windows.FontWeights.Normal, fontDataR);
