My company decided to move from Infragistics to Telerik .

For PDF development I am using Telerik.Windows.Documents.Flow.FormatProviders.Pdf and Telerik.Windows.Documents.Flow.Model.RadFlowDocument to create PDF.PDF is complex with tables/images etc but I did not have any issue there.Everything was as in Telerik online spec.

Now I have different issue that was almost stopover for me.PDF that I got with Telerik is 10 times bigger in size then with Infragistics.
Example bellow will create the simplest PDF doc with only one line of text, and that document is 245 kb.Same example with Infragistic is 14 kb.
Exact same relations is also when I add images in..I can see that Telerik document is much higher in quality [when I put images] but we prefer size/performance then quality of PDF.

Can you point what I have to change? Is any FormatProviders.Pdf settings that I can use to create smaller size document ?Or ?

 

class TEST
    {
        public void ExportToPdf(string PdfURL)
        {
            Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider provider =
                new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
            using (Stream output = File.OpenWrite(PdfURL))
            {
                Telerik.Windows.Documents.Flow.Model.RadFlowDocument document = CreateRadFlowDocument();
                provider.Export(document, output);
            }
        }
        private Telerik.Windows.Documents.Flow.Model.RadFlowDocument CreateRadFlowDocument()
        {
            RadFlowDocument document = new RadFlowDocument();
            RadFlowDocumentEditor editor = new RadFlowDocumentEditor(document);
            editor.ParagraphFormatting.TextAlignment.LocalValue = Alignment.Justified;
            Section section = editor.InsertSection();
            section.PageMargins = new Telerik.Windows.Documents.Primitives.Padding(4);
            section.PageOrientation = Telerik.Windows.Documents.Model.PageOrientation.Landscape;
           
            //test text
            editor.InsertText("TEST Telerik.Windows.Documents.Flow.Model.RadFlowDocument PDF ");

            return document;
        }
       
    }

 

 

Hi Team,

I need to automate a scenario of comparing 2 PDF files based on the content, format, alignment, etc. Is it possible to do it using Telerik Test Studio or any other telerik products.

Thanks,

Why does the following code return a transparent image?
The WHITE is transparent.

PdfFormatProvider provider = new PdfFormatProvider(file, FormatProviderSettings.ReadOnDemand);
RadFixedDocument document = provider.Import();
ThumbnailFactory factory = new ThumbnailFactory();
RadFixedPage page = document.Pages[0];
System.Windows.Media.ImageSource source = factory.CreateThumbnail(page, page.Size);

var image = (BitmapSource)source;
BitmapEncoder encoder = new PngBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(image));
using (var ms = new MemoryStream())
{
   encoder.Save(ms);
   ms.Position = 0;
   return ms;
}

Thankx, Harry

I am very exciting for this new function, but it is seem not support chinese as well. I convert a xlsx file that contain chinese to the pdf. the chinese word disappeared.....

I figured out this solution [code bellow] but is any other solution [probably it is] that I can use ?
Can use directly somehow System.Drawing.Font :
System.Drawing.Font fArialB  = new System.Drawing.Font("Arial", 18, System.Drawing.FontStyle.Bold);
instead to use Run object for every cell as bellow ?


        private void SetCellStyle(ref Telerik.Windows.Documents.Flow.Model.TableCell cell, string CellTxt, double CellSize)
        {
            cell.Shading.BackgroundColor = new ThemableColor(System.Windows.Media.Colors.White);
            cell.PreferredWidth = new TableWidthUnit(CellSize);
            Paragraph cellPar = cell.Blocks.AddParagraph();
            cellPar.TextAlignment = Alignment.Right;
            Run runCellTextFormat = cellPar.Inlines.AddRun(CellTxt);
            runCellTextFormat.FontSize = 18;
            runCellTextFormat.FontWeight = FontWeights.Bold;
            runCellTextFormat.FontFamily = new ThemableFontFamily(new System.Windows.Media.FontFamily("Arial"));
        }
Sorry to bother you guys with such probably simple questions, but I am in some short time frame to move stuff from Infagistic to Telerik.

I have to put 2 tif images on same page, one is regular "check" size,  other is "T4" doc size ...
Page orientation is landscape I did calculation , resizes images, everything works great ... BUT
"check image" position is on the bottom of page ?

I need it on top of page. Tried all alignments etc but did not figure out .

 I attached PDF page [as JPG] .

This is simple class that produced PDF.

Hi,

 

I create several documents using word processing and finally merge them into a single one using RadFlowDocument.Merge method. When you open that document in Word and insert a header, the header will only be set for single merged documents and not consistently across the whole document.

To repro:

- Create 2 RadFlowDocuments, with a single page and some simple demo text

- Merge them into a single one

- Export the merged document as docx.

- Open the exported document in word and add some text to the header on page 1.

- Scroll down to page 2 and confirm that the header is not there.

 

I can't tell whether this is a bug or a feature, but is there a way to workaround this? Ultimately I just want to merge several documents into one and have consistent headers and footers across the whole document.

Thanks in advance

Florian

I am using the RadSpreadsheet component and I am filling it with data from code behind. I would like to resize only the 'used' columns to a width that fits the content from each column. Something like the AutoFitWidth(). 

I tried to use this method (AutoFitWidth()) in a ColumnSelection, however I could only use in all columns, not just the ones I used and I took more than 2 minutes to open my window... I don't want this... As I fill my spreadsheet from code behind, I don't know how many columns I am using... It depends on the settings the user chose before the window opens...

Is there any solution for this?

Hi,

 I try to do the following: 

1. Load .docx document into the RichTextBox

2. Let the user edit the document

3. Perform MailMerge on the document

4. Export the result as PDF witha compliance level PdfComplianceLevel.PdfA1B

 

Only the WordsProcessing library supports the compliance level, so I need to convert the RadDocument to a RadFlowDocument.

When I export the RadDocument from the RichTexBox back to .docx I somehow loose all the styles (See WordBefore.png, WordAfter.png).

When I export the RadDocument to .rtf, it keeps the correct styles, but when I import it using the Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider, I get the following Exception:

 Do you have any proposal for me how I can accomplish this?

Hello,

I am trying to:

1 - Open a PDF created from Gridview's ExportToPdf function

2 - Draw a title on the page

3 - Save the PDF

When I run my code everything executes, but the final PDF is a blank page, but with the same length as the original PDF.

If I only open the page and then immediately save the PDF without attempting to draw on the page, the result is the same.

First, can PDFProcessing do this? I've heard that not all of your various PDF exports are compatible with all of the imports yet.

 If that is the case, do you have an alternate way for me to get some title text on the PDF file generated by GridView's ExportToPdf function?

 Thanks in advance,

 Scott
