Hi

I have been able to merge PDFs files all together into a single document by using File.OpenRead to read into a PdfFIleSource and then use the PdfStreamWriter WritePage method to concatenate them all.

But now I want to scale down the pages to be able to add page numbering.

I haven't been able to use scale down (reduce) using the previous method.

I have found another mechanism (https://www.telerik.com/forums/scaling-pdf-document) that is reading the input pages into a RadFixedDocument before adding them with WritePage to the PdfStreamWriter. This works (page are reduced as I want) but when input PDFs are annoted (textboxes or images), the annotations are not added to the scaled down output.

Do you have a sample that is doing that (merge scale down input files while keeping annotations)?

HTMLFormatProvider -> use custom font for imported html string

Hi!

How can I make a custom font work, when importing a HTML string and printing it to pdf? Im loosing the "ÄÖÜ" characters currently and know that this is a font related issue.

var htmlDocument = new Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider();

// Regular Font
byte[] fontData = System.IO.File.ReadAllBytes("fonts/verdana.ttf");
Telerik.Documents.Core.Fonts.FontFamily fontFamily = new Telerik.Documents.Core.Fonts.FontFamily("CustomVerdana");
FontsRepository.RegisterFont(fontFamily, FontStyles.Normal, FontWeights.Normal, fontData);

var doc = htmlDocument.Import("<html><body style=\"font-family:CustomVerdana;\">Das ist ein test. <br> <strong>ÖOÜUÄA</strong></body></html>");

var fileName = "output.pdf";
var pdf = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
using (Stream output = System.IO.File.OpenWrite(fileName))
{
      pdf.Export(doc, output);
 }

How to add invisible signature to existing PDF

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?

Best

Show page numbers, repeat page headings, crop away white space around content, make a block use 100% of the page height

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.

Insert document inside a run of another document

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.

else if (currentRun.Text.EndsWith("Template»"))
{

string ebrTemplateName = currentRun.Text.Substring(7, currentRun.Text.Length - 8);
var currentT = ModifyTemplate(ebrTemplateName, jsonToken + "[" + i + "].");
if (currentT != null)
{

// documents.Enqueue(new DocumentsStack { document = currentT, run = currentRun });
currentRun.GetEditorBefore().InsertDocument(currentT);
//editor.InsertDocument(currentT);

}

}

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

PDF Document Page Size

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.

// ----------------------------------------------
// Print Request Test Schedule Allocation

HTML to PDF font-family missing in .net

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);
