Hi.

I'm currently working with the large PDFs. I'm able to process PDFs up to 2.1 GB easily without any error using Telerik Document Processing. However, if I take a larger PDF (e.g. 2.8 GB), PdfFormatProvider.Import throws an IOException with the next message: "The parameter is incorrect. : {path}".
I'm using FileStream to provide a sample for the Import method.

I've checked it with the different samples, all have the same behavior. So, I guess, it will work for any PDF larger than 2.1 GB.

Steps to reproduce:

1.Create a zip archive for a txt file with password protection

2. Try updating the protected file and insert a new text line for example.


As a result,  an error occurs: System.ObjectDisposedException: 'Cannot access a closed Stream.'

In WorksheetPageSetup, you can only get the PageSize, but not set it. The only way is through setting a PaperType.

 

This is because in Telerik.Windows.Documents.Spreadsheet.Model.Printing.SheetPageSetupBase, the only way to set the pageSize property is by setting a PaperType, then it uses PaperTypeConverter.ToSize(PaperType) to convert it to the pageSize. I cannot see any other way to set this to a custom size set by the user.

 

Please allow custom page sizing by adding a setter for the PageSize if possible. Thank you!

 


WorksheetPageSetup pageSetup = worksheet.WorksheetPageSetup;
Size pageSize = new Size(50, 80)
pageSetup.PageSize = pageSize; // produces cs0200
pageSetup.PageSize.Width = pageSize.Width; // produces cs1612
pageSetup.PageSize.Height = pageSize.Height; // produces cs1612

Hello, I had many problems with version 2023.1.117, latest stable 2023.2.606 is unusable also due to issue with scanned documents etc, so I tried 2020.2.703-hotfix, but I am getting other set of issues.

Unfortunately I cannot share the documents, since they are confidential.

With some documents I am getting this error:
Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Objects.FormXObject'.

 

Loading Code:

            PdfFormatProvider pdfFormatProvider = new();

            RadFixedDocument document = pdfFormatProvider.Import(bytes);

I'm trying to use the PdfFormatProvider to import a pdf. I've tried to import multiple different pdfs with the code below, but they all throw an exception with "System.InvalidOperationException: 'Import not supported.'" and no other info. Is this a bug or am I not calling the correct method to import a pdf?

var providerPDF = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
providerPDF.Import(File.ReadAllBytes(@"D:\TestDocs\TestImage.pdf"));

Hello,

I'm using Telerik Documents Processing 2023.1.410

With WordsProcessing, if I add a table in a footer it will automatically add a space after the table

Here an example, my table is the same size as my image in background and I removed all margin of the section:

Here the code:


Footer footer = section.Footers.Add(HeaderFooterType.Default)
section.PageMargins = new Padding(0,96,96,0);
section.FooterBottomMargin = 0;

Table table = footer.Blocks.AddTable();
TableRow row = table.Rows.AddTableRow();
TableCell cell = row.Cells.AddTableCell();
Paragraph paragraph = cell.Blocks.AddParagraph();
paragraph.Inlines.AddRun("Something");

 

I didn't any properties to manage spaces around a Table like in Paragraph.

It can be reproduced without the image

Work around:

If I add a new paragraph at the end and remove all spaces of this paragraph then it works

Here the code added:


paragraph = footer.Blocks.AddParagraph();
paragraph.Spacing.SpacingAfter = 0;
paragraph.Spacing.SpacingBefore = 0;
paragraph.Spacing.LineSpacing = 0;

 

Regards,
Hervouet Thomas

When importing an XLSX that has "Date" number-formatted cells, and those cells have the 5-digit representation of th edate, XslxFormatProvider.Import(bytes) will throw a KeyNotFoundException. The exception message is "The given key '58' was not present in the dictionary" for the particular case we're looking at.

Unfortunately, we cannot provide the file itself, as it has PHI in it. And, when we open it in Excel and resave it, Excel will automatically convert the 5-digit representation to a normal date. This new file will import just fine. However, we're trying to cut out that intermediate step.

Pertinent portion of the stack trace:
   at System.ThrowHelper.ThrowKeyNotFoundException[T](T key)

When exporting RadFlowDocument that contains TOC field, resultant PDF document should contain link point to the page shown in TOC.


note this is different from already existing request as this request is to link to the page, which is possible in telerik PDF export as demonstrated here and not to the bookmark.

1. Line Height is not converted properly.  for example, if we set the line height is 1.5 in angular UI editor, in PDF is not shown properly,

2. Table alignment is not proper -  After resizing the in the angular editor, the same alignment is not converted in PDF. I think colgroup and cols custom tags are not considering while converting the PDF.

According to the Pdf Specification, the ExtGState property is optional but in this specific scenario the property is not omitted but just the object implementation.

This case can be handled using the Handling Exceptions mechanism.

I have read that there limitations to PDF files being imported, however, the file being imported  was generated with FixedContentEditor, so, should be able to import?

  using (Stream stream = Stream)
        {
          try
          {
            this._document = provider.Import(stream);
            _InputPath = fileName;

          catch (Exception e)
          {
            Errors = "Could not open file " + fileName + ": " + e.Message;
            this._document = null;
          }

Hi, 

 

I am trying to convert a HTML body to a PDF using HtmlFormatProvider and PdfFormatProvider. 

It works well when I try to create a pdf with "normal" characters, but when I use characters like "åäö" the characters is either missing or replaced with other character. 

I have found a similiar issue but that was due to the fact that the person was using .net core I am using .net framework. 

Am I missing something when I am converting it to a PDF or is there a limitation with special characters like "åäö". 

 


        private string CreateAndStorePdf(string htmlBody)
        {
            Telerik.Windows.Documents.Extensibility.JpegImageConverterBase jpegImageConverter = new Telerik.Documents.ImageUtils.JpegImageConverter();
            Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.JpegImageConverter = jpegImageConverter;

            var provider = new HtmlFormatProvider();
            var document = provider.Import(htmlBody);
            var exportProvider = new PdfFormatProvider();
            var fixedExportProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
            var fileName = "_original.pdf";

            try
            {
                using (var outputStream = new MemoryStream())
                {
                    exportProvider.Export(fixedExportProvider.ExportToFixedDocument(document), outputStream);
                    outputStream.Seek(0, SeekOrigin.Begin);
                    var pdfBytes = new BinaryReader(outputStream).ReadBytes((int)outputStream.Length);

                    return fileName;
                }
            }
            catch (Exception ex)
            {
                Log.Error(ex, "The pdf could not be created.");
                return null;
            }
        }

Dear Team,

when I create a pdf with your components (RadFixedDocument, RadFixedPage, FixedContentEditor) I cannot add a "german umlaut" in that report because then it cannot be viewed in your own pdfviewer- control (the exception is: Error loading document: Position is out of range).

I tried to solve this in "creating/ loading" arial.ttf as external font (even this is weird as idea), but this also did not work.

What is your solution for that?

I bought the Telerik components basically for PDF processing, this simply needs to work...

Many thanks for an urgent update on that!

Best regards

Tobias
