I am having trouble positioning text using text fragment. I'm not sure if its a scaling issue during import or what

Below is an extract that failes

I created a PDF completely gray with a black box starting at 100x100 pixels from the top left corner (https://www.pastefile.com/sjKGiJ)

The Original PDF was created by printing a blank page from work through adobe acrobat (for sizing) and then edited in illustrator to add the image.

Via the processor

The file is the imported using PdfStreamWriter and result written to a memory stream

The memorystream is the imported using RadFixedDocument and then text is added at 100x100 position.

Result is written to a file

Resulting file (https://www.pastefile.com/4HZwvR)

The text does not appear at 100x100 but at at ~ 74x70ish

the text font is not Helvetica but Arial

the font size is not 10pt but 5.63 pt

Code below (result is test4.pdf)

Imports Telerik.Windows.Documents.Fixed.FormatProviders.Pdf

Imports Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Streaming

Imports Telerik.Windows.Documents.Fixed.Model

Public Class Form1

Public pageLetter As New System.Windows.Size(816, 1056)

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

'Load file into byte array

Dim page1 As Byte() = ReadFile("d:\test2.pdf")

Dim originalsize As String = ""

' Load source document

Dim sourceDocument As New IO.MemoryStream(page1)

Dim sourceDocumentPDF As New PdfFileSource(sourceDocument)

Dim resultIO As New IO.MemoryStream

Using fileWriter As PdfStreamWriter = New PdfStreamWriter(resultIO)

' Create file same size as source

Using targetPDF As PdfPageStreamWriter = fileWriter.BeginPage(pageLetter)

' Store original size to write it out later

originalsize = sourceDocumentPDF.Pages(0).Size.Width & "x" & sourceDocumentPDF.Pages(0).Size.Height

' Write file

targetPDF.ContentPosition.Clear()

targetPDF.ContentPosition.Translate(0, 0)

targetPDF.ContentPosition.Scale(1, 1)

targetPDF.WriteContent(sourceDocumentPDF.Pages(0))

End Using

Dim provider As New PdfFormatProvider()

Dim doc1 As RadFixedDocument = provider.Import(resultIO.ToArray)

Dim pg As RadFixedPage = doc1.Pages(0)

Dim t As Telerik.Windows.Documents.Fixed.Model.Text.TextFragment = New Telerik.Windows.Documents.Fixed.Model.Text.TextFragment()

t.Font = Fonts.FontsRepository.Helvetica

t.FontSize = Telerik.Windows.Documents.Media.Unit.DipToPoint(10)

t.Text = "TEST TEXT PDF SIZE" & originalsize

pg.Content.Add(t)

t.Position.Translate(100, 100)

Dim b() As Byte = provider.Export(doc1)

Dim io2 As New IO.FileInfo("d:\test4.pdf")

Dim sw As IO.FileStream = io2.OpenWrite()

sw.Write(b, 0, b.Length)

sw.Close()

End Sub

Shared Function ReadFile(filename As String) As Byte()

Dim io As New IO.FileInfo(filename)

Dim fs As IO.FileStream = io.OpenRead

Dim b() As Byte

ReDim b(io.Length)

fs.Read(b, 0, io.Length)

fs.Close()

Return b

End Function

End Class

Error exporting from excel and merging PDF documents

Hi,

We have a threaded service where we export excel documents to PDF documents (using Telerik.Windows.Documents.Spreadsheet.FormatProviders.Pdf.PdfFormatProvider.Export) and then merge the PDF with other PDF documents (using Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider.Import and RadFixedDocument.Merge). We make sure to dispose the Workbook of the excel document and the MemoryStream from exporting to PDF.

After some time we start getting the following error, until we restart the service.

One or more errors occurred.

Word experienced an error trying to open the file

I am trying to export my document but I am getting the error attached to the thread.

I can fix this by going into the properties of the document and checking the unblock box. Is there a way to do this in the export to be able to just open the document without having to go into its properties? I get the same error on the demo page for generating word documents https://demos.telerik.com/aspnet-ajax/wordsprocessing/generate-documents/defaultcs.aspx

Here is my code for export

RadFlowDocument document = report.GenerateDoc();

DocxFormatProvider provider = new DocxFormatProvider();

MemoryStream ms = new MemoryStream();

provider.Export(document, ms);

byte[] byteArray = ms.ToArray();

ms.Dispose();

return File(byteArray, "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "AAR.docx");

PdfStreamWriter.WritePage to a MemoryStream/Byte() not working

When writing to a FileStream with PdfStreamWriter.WritePage, either implicitly or after the PdfStreamWriter loses scope... A PDF document gets created correctly specifically with the ending portion of the PDF document that handles the %EOF and the portions just prior to that.

When this same process is done with a MemoryStream (not a file) for the purposes of taking that "PDF DOCUMENT" and saving the byte() to a database, that ending part of the PDF document doesn't get created... and thus it becomes a corrupt (unreadable) PDF file. This ending portion of the PDF document that I'm referring to looks like this: (example):

xref
0 26
0000000000 65535 f
0000350400 00000 n
0000350089 00000 n

0000000204 00000 n
0000000440 00000 n
0000000699 00000 n
0000150134 00000 n
0000150319 00000 n
0000150473 00000 n
0000150732 00000 n
0000232360 00000 n
0000232502 00000 n

%%EOF

What do I have to do after .WritePage with a backing MemoryStream... to eventually grab that byte() with a complete PDF document that includes the %%EOF piece... like for example:

Dim contentLength As Int64 = msOutputStream.Length

Dim aryBuffer(contentLength - 1) As Byte

aryBuffer = msOutputStream.ToArray

After the WritePage, the above will NOT include that ending segment of the PDF document/file.

I can't really .Close the MemoryStream, because then it isn't accessible at all... Does it need to be a part of a USING statement in some way? I have the PdfStreamWriter in a USING... and I do NOT need to have the FileStream as part of a USING and it works correctly.

Some full sample code:

Dim documentsToMerge As String() = {"d:\SignaturePageToAppend.pdf"}

Dim msOutputStream As MemoryStream = New MemoryStream()

Using memoryWriter As Pdf.Streaming.PdfStreamWriter = New Pdf.Streaming.PdfStreamWriter(msOutputStream)

Dim pdfOutputProv As Pdf.PdfFormatProvider = New Pdf.PdfFormatProvider(msOutputStream)

For Each documentName As String In documentsToMerge

'This is initializing the MemoryStream with a good Byte() PDF from a DB

Dim msAddedPagePDF As MemoryStream = New MemoryStream(docAddedPage.FSDocument)

Using fileToMerge As Pdf.Streaming.PdfFileSource = New Pdf.Streaming.PdfFileSource(msAddedPagePDF)

Dim pdfAddedPage1 As Pdf.Streaming.PdfPageSource = fileToMerge.Pages.FirstOrDefault

memoryWriter.WritePage(pdfAddedPage1)

End Using

'TBD

Dim contentLength As Int64 = msOutputStream.Length

Dim aryBuffer(contentLength - 1) As Byte

aryBuffer = msOutputStream.ToArray

'aryBuffer will NOT include the ending PDF segment to complete the PDF document

'Saving Byte() to DB

'docSource.FSDocument = aryBuffer

'trDocumentRepository.Update(docSource)

'trDocumentRepository.FlushAndSaveChanges()

Next

End Using
