[ERROR] LibreOffice/OpenOffice .docx files HtmlFormatProvider Export

Hi;

I'm having problems, when I try to export with HtmlFormatProvider the OpenOffice/LibreOffice docx files.

If the file is created with MSWord there's no problems, all works fine, the problem is with LibreOffice/Openoffice generated-documents.

Please, I need help 'cause some of my customers uses LibreOffice to create the docx documents.

+++++++++++++++++++++++ CODE ++++++++++++++++++++++++++

docxProvider = new DocxFormatProvider();
htmlProvider = new HtmlFormatProvider();

if(this._DocXByteArray == null)
this._DocXByteArray = System.IO.File.ReadAllBytes(this._DocXPath);

document = docxProvider.Import(this._DocXByteArray);

htmlProvider.ExportSettings.DocumentExportLevel = DocumentExportLevel.Fragment;
htmlProvider.ExportSettings.ImagesExportMode = ImagesExportMode.Embedded;
htmlProvider.ExportSettings.StylesExportMode = StylesExportMode.Embedded;

string html = htmlProvider.Export(document); //heres crash with the down error trace

+++++++++++++++++++++++ CODE ++++++++++++++++++++++++++

I'm always getting this error

Export from RadFixedDocument to Stream

Hello,

I'm attempting to split a Pdf by removing pages. After page removal, I export the RadFixedDocument back to a PDF through a stream. I've tried various streams like MemoryStream and FileStream without luck. All PDFs come about with blank pages. Code is below.

public static IEnumerable<string> SplitPdf(PdfFileDefinition pdfFileDef)

{

List<string> pdfs = new List<string>();

Stream stream = null;

PdfFormatProvider formatProvider = new PdfFormatProvider();

// Save temp file to disk

var path = @"c:\temp";

if(!Directory.Exists(path))

Directory.CreateDirectory(path);

// Pdf streams must support read & seek operations

var fileUri = new Uri(pdfFileDef.FilePath);

// Is pdf a file or resource

if (fileUri.Scheme == "file")

{

var tempFilePath = Path.Combine(path, "temp.pdf");

File.Copy(Path.Combine(path,fileUri.LocalPath), tempFilePath,true);

stream = File.Open(tempFilePath, FileMode.Open,FileAccess.Read);

}

else if (fileUri.Scheme == "pack" && fileUri.Host.Contains("siteoforigin"))

{

stream = Application.GetRemoteStream(fileUri).Stream;

}

foreach(var pageBreak in pdfFileDef.PageBreaks)

{

RadFixedDocument document = new PdfFormatProvider(stream, FormatProviderSettings.ReadOnDemand).Import();

RadFixedDocument splitDocument = new RadFixedDocument();

splitDocument = document;

for (int pageNumber = splitDocument.Pages.Count - 1; pageNumber >= 0; pageNumber--)

{

if(!pageNumber.IsBetween<int>(pageBreak.StartPage, pageBreak.EndPage))

{

splitDocument.Pages.RemoveAt(pageNumber);

}

// Generate temp pdf file for review

var fileName = Path.Combine(path, Path.GetRandomFileName());

fileName = Path.ChangeExtension(fileName, ".pdf");

// Export filestream to Pdf

using(var fs = new FileStream(fileName,FileMode.Create))

{

formatProvider.Export(splitDocument, fs);

}

pdfs.Add(fileName);

}

return pdfs;

}

Auto Fit Column Widths

Is there a way to set column widths to auto fit? I see that RadSpreadProcessing has ColumnSelection.AutoFitWidth(). Is there any way to get that functionality with IColumnExporter? All I see is SetWidthInPixels() and SetWidthInCharacters(), but I can't get either of those values when creating the spreadsheet.

If not, are there any plans for this functionality?

How to set the cursor position in docx using RadFlowDocumentEditor

I am starting with an existing document, which is attached, and trying to figure out how to correctly set the position so I can start adding text at a certain point in the document. The key is how do you find that point so the RadFlowDocumentEditor can begin adding and creating tables in the document. I am not trying to do a mail merge. All I want to do is get a certain position within the document to begin adding text. Is there something special you need to do inside of the word document itself? Here is the code I used to try and hopefully set the position, but it adds text to the top of the document and wipes out the existing text. If you could provide me a code snippet or some guidance, I would appreciate it.

DocxFormatProvider provider = new DocxFormatProvider();
using (Stream input = File.OpenRead("Input.docx"))
{
RadFlowDocument document = provider.Import(input);
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
Run firstRun = document.EnumerateChildrenOfType<Run>().First();
editor.MoveToInlineEnd(firstRun);
editor.InsertText("Hello word!");

using (Stream output = File.OpenWrite("Output.docx"))
{
provider.Export(document, output);
}
}

Unreadable text after importing/exporting

Hello,

Importing and exporting this pdf results in an unreadable text.

The attached image "ImportedFile" shows how the imported pdf looks like. The other image, "ExportedFile", shows the result of the export.

Here's a code example to import and export:

private static void ImportAndExport()

{

var fixedDocFormatProvider = new Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider();

RadFixedDocument fixedDocument;

var importFile = @"C:\ImportedFile.pdf";

using (var stream = File.OpenRead(importFile))

{

fixedDocument = fixedDocFormatProvider.Import(stream);

}

var formatProvider = new Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider();

var exportFile = @"C:\ExportedFile.pdf";

using (var stream = new FileStream(exportFile, FileMode.Create))

{

formatProvider.Export(fixedDocument, stream);

}

Any ideas why is this happening?

Thanks

Exporting Unicode characters

Hi,

Is it possible to export Unicode characters from supplementary planes (above Plane 0), i.e. those that need more than 2 bytes of storage? They seem to be silently ignored (normally a replacement character such as '?' is shown for unsupported code points).

A simple test shows that small value code points are OK but longer ones are ignored. This should show 2 smiley faces:

var editor = new FixedContentEditor(container);

editor.DrawText("Smiley face OK: \u263A Smiley ignored: \uD83D\uDE0A");

Any comments/suggestions would be welcome.

Thanks,
Chris
