Questions on Telerik Document Processing Forum

I work for a company that heavily leverages Telerik controls in our core applications. I’ve been tasked with exploring the PDF options available in hopes of replacing our current PDF exports with Telerik equivalents to help move away from an unwanted software license.

In exploring the demos and product features it appears to me that rendering HTML content is limited to the RadClientExportManager and therefore is client side only, while server document creation requires the more elemental building of documents by plotting text, and graphics manually via .NET code.

Is this an accurate assessment? What would you recommend to someone wanting to render HTML content on the server where there is no actual browser or user involvement?

We currently convert data populated WebForm pages into PDF files all on the server that are never delivered to a user via browser interaction, or even requested by a browser (automated generation.)

Aside from an HTML source being easier to use and maintain, it would plug right into our existing situation and not require use to reconstruct our forms in C#. That is obviously a more attractive option for us.

I am very impressed with the functionality of the client side rendering, it just doesn’t appear to cover a lot of common use cases that we happen to fall under.

RadFixedDocument Import Bug Issue

I want to report bug with this code:

byte[] file = File.ReadAllBytes("Test.pdf");
RadFixedDocument document = null;
var prov = new PdfFormatProvider();
using (var input = new MemoryStream())
{
input.Write(file, 0, file.Length);
document = prov.Import(input);
}
When I tried to import my document to RadFixedDocument it says:
Ex: {"Stack empty."}

Generated Telerik report in PDF gives not readable text

Good morning,

When going through the PDF with PdfProcessing, it gives me weird text in some elements which I presume is metadata of the pdf.
As for other PDFs who are not created out of Telerik it works fine...

I also checked the Telerik forum a lot, desperately finding a possible and proper solution/alternative for this, but unfortunately.

I just simply need to read normal text out of my Telerik report, I don't want to export the text, I only wanna extract that text so I can draw an image under it.

My question is simple : Does Telerik have solutions to deal with this issue?

I have attached a snippet of my problem when I'm debugging in Visual Studio and the Telerik Report I try to read.
Thanks

Kurt Berlanger

PdfStreamWriter

I'm trying to write a simple script to merge two files together.

The files that are created show as corrupt. Is there something im doing wrong?

Sub Main()

Dim file1 As Byte() = ReadFile("e:\test1\test1.pdf")

Dim result As New IO.MemoryStream

Dim fileWriter As New PdfStreamWriter(Result, True)

Dim pdfSource As New PdfFileSource(New IO.MemoryStream(file1))

For Each pg As PdfPageSource In pdfSource.Pages

fileWriter.WritePage(pg)

Next

Dim b As Byte()

b = Result.ToArray()

Dim writer As IO.FileStream = IO.File.OpenWrite("e:\test1\abc12222.pdf")

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

writer.Close()

End Sub

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

RadFlowDocument to PDF - ArialNarrow font issues

Hello,

I have a RadFlowDocument that I am exporting to PDF via the standard flow PDFFormatProvider. If the document has some text that used the Arial Narrow font that is either bold, italicized or both the PDF output is always showing just plain Arial Narrow. This seems to be the only font that is having this problem.

Has anyone else encountered this or have any suggestions on how to fix it?

Thanks,

-Tom
