Missing text when exporting PDF to Image

Question

See attached project. When I export the PDF to PNG, the 3rd line of text in the paragraph is missing some text. This also happens in the PDF Viewer when it converts the PDF to an image. I am using 18.4.0.33.

Regards,

Arthur

Hi Arthur, 
we can extract the text correctly by using our  Syncfusion.AspNet.Mvc5.PdfViewer NuGet package. In this we are using Pdfium rendering engine for robust rendering and extracting the text with accurate results. Kindly refer the sample and code-snippet about performing  the extract text.  
Sample:  https://www.syncfusion.com/downloads/support/directtrac/general/ze/PdfExportImage344295409.zip 
  
UG documentation: https://help.syncfusion.com/js/pdfviewer/how-to-use-pdfium-rendering-engine-in-pdf-viewer#exporting-pdfs-as-raster-images 
 
 
Code snippet: 




PdfViewerHelper viewer = new PdfViewerHelper(); 
                //To load the PDF document. 
                viewer.Load(pdfFile); 
                //Exports the first page of the PDF document into image   
                Bitmap[] _imgs = viewer.ExportAsImage(0, viewer.PageCount - 1); 
 
Please let us know if you have any concerns about this.
