PDF files created by e-Synergy cannot be converted

My product uses Aspose.Total for .Net to display files in a web based viewer. For that purpose, the files are converted to png. That doesn’t work with the attached PDF file, created by the financial software e-Synergy:

Code to reproduce the problem is as follows:

string sPdf = “Fails.pdf”;
using (Aspose.Pdf.Document pdf = new Aspose.Pdf.Document(sPdf))
Aspose.Pdf.Page pg = pdf.Pages[1];
Aspose.Pdf.Devices.BmpDevice bmpDevice = new Aspose.Pdf.Devices.BmpDevice();
MemoryStream ms = new MemoryStream();
bmpDevice.Resolution.X = 300;
bmpDevice.Resolution.Y = 300;
bmpDevice.Process(pg, ms);
Bitmap bmp = new Bitmap(ms);
bmp.Save(sPdf + “.png”, System.Drawing.Imaging.ImageFormat.Png);

The cause is probably the image format used by e-Synergy. All PDF files of the customer having this problem are produced by this software and cannot be converted.

Best regards,

Hi Berend,

The development team is working on resolving the issue reported earlier however as a workaround, you may consider using Viewer application of our sister company named GroupDocs to view/display the PDF files directly in your web application.

Hi Berend,
