Bug with drawing with release 2024.3.806 (not with release 2024.2.426)

Hi,

I have an existing xlsx file that contains graphics (drawing)

I simply open the workbook,

var workbook = CreateWorkbook();

byte[] bytes;

using (var output = new MemoryStream())
{
    new XlsxFormatProvider().Export(workbook, output);
    bytes = output.ToArray();
}

File.WriteAllBytes("c:\\Logs\\test.xlsx", bytes);


private Workbook CreateWorkbook()
{
    Workbook workbook;
    IWorkbookFormatProvider formatProvider = new XlsxFormatProvider();
    FileStream? stream = null;
    try
    {
        stream = File.Open("AnalyseImpayeTemplate.xlsx", FileMode.Open);
        workbook = formatProvider.Import(stream);
    }
    catch (IOException ex)
    {
        throw new IOException("The file cannot be opened. It might be locked by another application.", ex);
    }
    finally
    {
        stream?.Dispose();
    }

    return workbook;
}

When I open the result file, with release 2024.3.806, I got an error. It delete drawing parts :

Partie supprimée: /xl/drawings/drawing1.xml partie. (Forme de dessin)

With release 2024.2.426, it works fine.

Any ideas why?

WordsProcessing: Row height when exporting to PDF

Hi

I have a problem with row height when processing docx files and exporting to pdf.
Export does not respect the height of a table row if the height of a given row is lower than the content of cells in that row. However, if the height of the row is greater than the content, then it is ok.
During processing, a given row has its height set as Exact and a specific value in pixels, but after export, the height of a given row in the table adjusts to the content.

Maybe there is a workaround for this problem?

Html to PDF Bold appears inconsistent (Telerik 2024.3.802)

I have the following code that shows the bold formatting from HTML to PDF appears inconsistent.

The last table has all the cells wrapped in <b> tags, but they are not rendered bold in the PDF. There seems to be some correlation to the length of the text (short text sometimes will be bold). I have also tried <strong> tags and CSS that applies bold. It does not matter which font is chosen.

Inconclusive observation: It appears that if the bold text line wraps inside a cell, it doesn’t apply bold. Text that does not wrap in the cell appears to apply bold.

Any help appreciated.

PDFProcessing: Adding PDF Page from a PDF Document to another PDF Document

I tried doing the following:

using Stream stream = File.OpenRead(fileName);
RadFixedDocument pdfDocument = new PdfFormatProvider().Import(stream);
RadFixedDocument pdfNew = new();
pdfNew.Pages.Add(pdfDocument.Pages.First());

I get the following error:

System.ArgumentException: 'The document element is associated with another parent. (Parameter 'item')'

Is there a way to clone a page, so it can be added to another document?

How to render unicode checkbox u2612 and u2610 in PDF? Works ok in Word (Processing 2024.3.802)

I am having trouble getting some HTML converted to PDF to render Unicode checkboxes.

\u2612 ☒ and \u2610 ☐

They appear ok in the word conversion, but are missing in PDF

Here is the same code

PdfProcessing library 2024.3.802 throws exception The document element is associated with another parent. (Parameter 'item')

Greetings,

I am using Telerik 2024.3.802 PdfProcessing library.

We have used the Telerik library to convert a HTML document to Word DOCX format.

This process completes successfully.

Then using Telerik PdfProcessing, executing a Word to PDF process.

The method throws an exception shown below.

The code is fairly trivial:

public static byte[] ConverDocxToPdf(byte[] docxBytes)
{
    var docxProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
    var pdfProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();

    var document = docxProvider.Import(docxBytes);

    using var memoryStream = new MemoryStream();
    pdfProvider.Export(document, memoryStream);
    return memoryStream.ToArray();
}

If we open the Telerik produced docx file, in word, and resave it (no changes)

Then the Word to PDF process works. So it may imply there is an error in the HTML to word conversion which is creating a invalid docx file.

Is there anyway to "validate" a docx file with the Telerik tooling?

EDIT: When using this OpenXML validator: https://learn.microsoft.com/en-us/office/open-xml/word/how-to-validate-a-word-processing-document?tabs=cs-0%2Ccs against the Telerik created word docx file, I get a list of 51 errors. So Telerik Html to Docx perhaps is not creating a valid docx for various nodes.

Here are the list of errors

Trim spreadsheet

I see Sreadsheet processing has row removal feature but it seems you need to know the range of rows you want to remove.

How would you recommend acheiving something like a trim functionality? Excel spreadsheets in my experience are notorious for having potenatially pages and pages of empty rows after all the actual content. In fact I am working with one like that now.How can I get rid of those empty rows?

Thank you!

Telerik Format Provider to export PDF isn't accurate.

I am using a PdfFormatProvider to export the stream of a DocX.

I am displayinga preview of this docx as PDF within my application. The problem is, the PDF is not showing the correct spacing, line numbers and other items listed in the docX file.

When I save DocX as PDF it will display everything needed.

ColumnSpan not working as expected.

Hi folks,

we have a requirement for a PDF that we must draw a table with different columns counts and sizes. Our approach is to generate a defined number of cells in a row (18) and merge them appropriately as we need them. Find a test below.

void AddSecondTable(RadFixedPage page)
{
    var blackBorder = new Border(1, new RgbColor(0, 0, 0));
    var editor = new FixedContentEditor(page);    
    editor.Position.Translate(Unit.CmToDip(2), Unit.CmToDip(2));
    var table = new Table
    {
        LayoutType = TableLayoutType.AutoFit,
        DefaultCellProperties =
        {
            Padding = new Thickness(5, 5, 5, 5),
            Borders = new TableCellBorders(blackBorder, blackBorder, blackBorder, blackBorder) 
        }
    }; 

    for (var rowIndex = 0; rowIndex < 10; rowIndex++)
    {
        var row = table.Rows.AddTableRow();
        for (var cellIndex = 0; cellIndex < 18; cellIndex++)
        {
           var cell = row.Cells.AddTableCell();
           cell.PreferredWidth = Unit.CmToDip(1);
           var b = cell.Blocks.AddBlock(); 
           b.InsertText(new FontFamily("Helvetica"), FontStyles.Normal, FontWeights.Normal, $"Cell: {cellIndex}");
        }    
 
        var firstCell = row.Cells[0];
        firstCell.ColumnSpan = 4;
    }   
    
    editor.DrawTable(table, Unit.CmToDip(18));  
}

We expect that the first cell be placed over the first four columns, but nothing happens at all. What do we miss here?

Further, we would expect that the next cell starts with cellIndex 4, as the first four (0-3) are “merged”.

WordsProcessing Protected Document Doesnt Unlock

I am generating a RadFlowDocument, and at the end protecting the entire document with a custom password like below..

                editor.Protect("TestPassword");

This works when I open the word document as expected, but when I go in MS Word to UNLOCK the document with my password, I am constantly told the password is incorrect.. Any advise on what I am doing wrong?
