Hi,

In one of my projects, I add a kind of 'stamp' to an existing pdf page by rendering an HTML page on top of the page. I do this with a third-party library other than Telerik.

To reduce the number of different licenses needed I try to accomplish this with the Telerik DPL but I can't figure out if this is possible, and if yes, then how?

Can I add a document page (ie imported from a htmlpage) on top of a page in an existing pdf (the original page should still be visible)

If it is possible then a small sample will be really helpful.

Thanks in advance!

I need pdf landscape orientation.

I export document, then change size:

pdf = pdfFlowProvider.ExportToFixedDocument(doc);
pdf.Pages[0].Size = new Size(1056, 816);

Problem that I have lot of space on the right side, probably because I exported document first.

But I can't change page size before this, because I don't have pages.

How to fix this?

I can rotate in RadFixedDocumentEditor using SectionProperties.PageRotation, but if I use

using (RadFixedDocumentEditor editorDocument = new(document))
        {          
            editorDocument.SectionProperties.PageRotation = Rotation.Rotate90;
            editorDocument.InsertRun("Test Run.");          
        }

using the tutorial on:

SpreadProcessing - Import and Export to Xlsm File Format Using XlsmFormatProvider | Telerik Document Processing

I have this code:

        Workbook workbook;

        IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsm.XlsmFormatProvider();
        using (Stream input = new FileStream(FileName, FileMode.Open))
        {
            workbook = formatProvider.Import(input);
        }

when trying to  open the file I get the following error:

Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

I have not done anything to the file other than attempt to open the file.    Some files can be opened, but many throw this error.  I cannot determine what the problem is and can't figure out what the 'index' is that's being referred to.  

I am following the guide to create a PDF (First Steps | Telerik Document Processing)

I installed the UI for ASP.NET Core. I could find the three DLLs referenced in the example but the documentation states: for .NET Core/.NET 5+ project the additional DLLs are required:

• Telerik.Documents.Flow.FormatProviders.Docx.dll
• Telerik.Documents.Flow.FormatProviders.Pdf.dll

Where are these dll's located?

I would like to add a superscript to text I am adding to a block.  I tried adding the text to a block, and then a TextFragment to the block, but I can't seem to move the text up as a superscript.

block.InsertText(text ?? string.Empty);
var frag = new TextFragment(superscript);
frag.FontSize = fontSize - 2;
block.Insert(frag);

I tried using frag.TextRise but it doesn't seem to affect the vertical offset of the fragment no matter what values I use. I also tried using frag.Position, but that doesn't affect it either.   Clearly I am missing something.  Perhaps I should use another approach?

Thanks in advance,

I am starting with the Telerik Document processing libraries.  I have a simple excel file that I would like to import into a list to work with in my program.  

I have an imported workbook and worksheet that seems to work.  When I try to get the data from a test cell however:

string test;
test = sheet.Cells[0,0].GetValue().ToString();

instead of returning the value I put in the cell I get:

"Telerik.Windows.Documents.Spreadsheet.Model.RangePropertyValue`1[Telerik.Windows.Documents.Spreadsheet.Model.ICellValue]"

I have been reading the documentation and can't figure out what I am doing wrong.  

(for the record:

test = sheet.Cells[0,0].GetValue().Value.ToString(); returns 

"Telerik.Windows.Documents.Spreadsheet.Model.NumberCellValue"

so it isn't helpful either.)
