Hi Team,

                    i am trying to convert my HTML page to PDF. which i have done successfully but i got a problem with the contents of it. i want to search concerned  text after generating it but i used all three methods which was given in the sample examples  but i am unable to do so. Please help.

My code methods are below..

1.   its definitely Generate an Image

           using (System.Drawing.Image img = html.ConvertToImage(sourceUrl, Syncfusion.HtmlConverter.ImageType.Bitmap, (int)width,1500, AspectRatio.KeepWidth))
                    if (img != null)
                    {
                        PdfImage image = new PdfBitmap(img);
                        PdfLayoutFormat format = new PdfLayoutFormat();
                        format.Layout = PdfLayoutType.OnePage;
                        if (img.Size.Width > pageSize.Width)
                        {
                            image.Draw(page, new RectangleF(0, 0, pageSize.Width, (1500)), format);
                        }
                        else
                        {
                            //Bitmap
                            image.Draw(page, new RectangleF(0, 0, img.Width, (img.Height)), format);
                        }
                    }
                    else
                        Response.Write("Warning ! Please check the HTML link");


2.            using (HtmlToPdfResult result = html.Convert(sourceUrl, Syncfusion.HtmlConverter.ImageType.Metafile, (int)width, (int)height, AspectRatio.KeepWidth))
                {
                    if (result != null)
                    {
                        PdfMetafile mf = new PdfMetafile(result.RenderedImage as Metafile);
                        mf.Quality = 100;
                        PdfMetafileLayoutFormat format = new PdfMetafileLayoutFormat();
                        format.Break = PdfLayoutBreakType.FitPage;
                        format.Layout = PdfLayoutType.Paginate;
                        doc.PageSettings.Height = result.RenderedImage.Size.Height;
                        format.SplitTextLines = true;
                        format.SplitImages = true;
                        result.Render(page, format);
                    }

3.         using (HtmlConverter html = new HtmlConverter())
            {                
                html.ConvertToTaggedPDF(doc, sourceUrl);
            }

In all above three methods i use my SourceURL to generate PDF files but i got an image attached to that pdf in all these three methods.

i am using .Net, MVC, C# with visual studio 2013.

Sample file attached.

Hi Shobhit,

Thank you for using Syncfusion Products.

 

On our analysis with the PDF document which you have provided, we have found that the PDF contains Bitmapped image. Html Converter make use of MSHTML (IE Rendering Engine) to convert Web pages to Image, and then convert to PDF. With IE 9 and above there is a known issue that it generates only raster image. You can get more information on this from the following link:

http://msdn.microsoft.com/en-us/library/ee330732(v=vs.85).aspx#iviewobject_draw

 

As explained, to solve this, the key FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI should be updated in the registry. Please run the utility placed in the following location to perform the above changes automatically.

$system drive:\Program Files\Syncfusion\Essential Studio\$Version # \Utilities\PDF\Legacy Drawing

 

After these changes please try to convert the Html to PDF which will produce the sharper selectable text.

 

Thanks,

Karthikeyan.C

The full code I run is available here: http://share.linqpad.net/9owopm.linq

Any clue ?
Thanks in advance,

Yes, I'm 100% sure, also adding two snapshots of my system registry by regedit.
I've also restarted the pc, but no luck
