RadFixedDocument - Landscape & co

Hi from France ! (and excuse me for my bad english)

After 3 days on RadFixedDocument to make a PDF file, i need help !

I must make a PDF File based on my Asp.net Vb.net website (attached file)

i must make a document with "same" design : Landscape document and grids on left and on right

Dim document As New Telerik.Windows.Documents.Fixed.Model.RadFixedDocument

document.DocumentInfo.Author = "(c) Francelot"

document.DocumentInfo.Title = "Bilan Gestion"

Dim ex As New Telerik.Windows.Documents.Fixed.Model.Editing.RadFixedDocumentEditor(document)

ex.SectionProperties.PageRotation = Telerik.Windows.Documents.Fixed.Model.Data.Rotation.Rotate90

ex.InsertSectionBreak()

ex.InsertRun("TEST")

ex.InsertLine("Bilan Gestion")

ex.Dispose()

After this i got landscape document but my text is right to left (write not landscape, just rotate page ...)

Thank for your help !

File size limits?

I'm currently using Telerik.Windows.Zip 2016.2.606.40.

Are there any file size limits, either to individual files in a ZIP or to the ZIP as a whole?

I'm getting an exception "Relative offset of the Central Directory Start is too big" while trying to process a large (~3GB) stream.

Thanks.

[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);
}
}
