I am doing images extraction from PDF. Having trouble to create image (in any format) from EncodedImageData (https://docs.telerik.com/devtools/document-processing/api/telerik.windows.documents.fixed.model.resources.encodedimagedata) structre.

Can someone post a sample code. I tired with this sample (https://www.telerik.com/forums/manipulate-image-elements) but without success.

My image have FlateDecode filter, "DeviceRGB" ColorSpace and 8 BitsPerComponent (see attached).

Environment is .NET Core.

I need to be able to take a pdf that is already created, and I need to search for sections of the pdf, insert and/or change existing text, and resave the pdf.

I saw the FixedContentEditor, but I only saw how to add, I didn't notice how to search for text or replace it?

Could you point me in the right direction?

Thank you!

Hi,

I have a simple Excel file with just one sheet and one image in .xls and in .xlsx (attached in the zip file).

When reading the files using the XlsFormatProvider or XlsxFormatProvider, I get a workbook. When iterating the shapes on every sheet, I have a different result. I can retrieve the image using the XlsxFormatProvider in the xlsx file, but I'm not getting any shapes in the .xls file using the XlsFormatProvider.

Some code below:

var provider = new XlsxFormatProvider();
using (var fs = File.OpenRead("image.xlsx"))
{
    var workbook = provider.Import(fs);
    Assert.AreEqual(workbook.ActiveWorksheet.Shapes.Images.Count(), 1);
}

Should I be doing this differently? Or is this a known limitation?

I'm using version 2021.3.909.40.

Edit: just noticed that the same goes for charts.

Hello, 

I am currently trying to write in the "Modele.docx" document that is just a template. For each OperationAffecteeViewModel, I want to write in this template, and then copy what i just wrote in "documentFinal.docx". But the application crashes at the line 

documentFinal.Sections.Add(copySection);

with the following error : The document element is associated with another document

here's the code :

 private async Task GenererOperations()
        {
            RadFlowDocument document = new RadFlowDocument(); ;
            RadFlowDocument documentFinal = new RadFlowDocument();
            var docxProvider = new DocxFormatProvider();



            foreach (OperationAffecteeViewModel operationAffectee in OperationsAffectees)
            {
                using (Stream input = File.OpenRead("Modele.docx"))
                {
                    document = docxProvider.Import(input);
                }
                RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
                GoToBookmark(document, editor, "OUVRAGE");
                editor.InsertText(operationAffectee.LibelleOuvrage);
                GoToBookmark(document, editor, "OPERATION");
                editor.InsertText(operationAffectee.LibelleTypeOperation);
                GoToBookmark(document, editor, "DATE_PRÉVUE");
                editor.InsertText(operationAffectee.DatePrevisionnelle.Date.ToString("dd/MM/yyyy"));

            }

            //chargement de la police pour éviter de perdre les caractères spéciaux lors de l'exportation
            var fontData = File.ReadAllBytes(@"wwwroot/fonts/Calibri_Regular.ttf");
            FontsRepository.RegisterFont(new Telerik.Documents.Core.Fonts.FontFamily("Calibri"), FontStyles.Normal, FontWeights.Normal, fontData);

            var providerPdf = new PdfFormatProvider();
            using (Stream outStream = File.OpenWrite("sample.pdf"))
            {
                providerPdf.Export(document, outStream);
            }

            await InvokeAsync(() => this.StateHasChanged());
        }

        
        private void GoToBookmark(RadFlowDocument document, RadFlowDocumentEditor editor, string bookmarkName)
        {
            var bookmark = document.EnumerateChildrenOfType<BookmarkRangeEnd>().FirstOrDefault(rangeStart => rangeStart.Bookmark.Name == bookmarkName);
            if (bookmark != null)
            {
                editor.MoveToInlineEnd(bookmark.Paragraph.Inlines[0]);
            }
        }

Thanks for helping me ! 

Hello,

I have a weird situation, that the line:

run.FontWieght = FontWieghts.Bold;

doesn't work.

in second hand, every other character attribute is working perfectly (like FontStyle, FontUnderline, Font size and so on).

can anyone guess what could be the issue? 

Hello,

Is there a way we can add the signature captured via a SignaturePad and add it to the RadFixedPage? Also certify that signature with a x509 self signed certificate?

Thanks,

Hello,

I am exporting the text and image as shown in the attached program. The resulting output shows the text floating around the image which is left aligned:

What I want to achieve now is the reverse of it so that the image gets right-aligned with text aligning to the left and floating around the image on the right.

How do I do that?

Thanks,

Adnan
