PDF to png conversion low quality and image blurred

Aspose.PDF version 17.5

using (var imageStream = new FileStream(settings.ResultFilePath, FileMode.Create))
    {
        ImageDevice device;
	    var resolution = new Resolution(100);
	    device = new PngDevice(resolution);
        device.Process(document.Pages[settings.PageNumber], imageStream);
        device.Close();
    }

Also try to change resolution to 120,500…
and try to use new JpegDevice(100, 100)

At the end I print the resulted png file and I see that image blurred than original.

Thanks for contacting support.

We have tested the scenario in our environment with Aspose.PDF for .NET 18.12 by converting PDF document into PNG and printing resultant image into PDF using soft printer. We did not notice any blur view in printed PDF. We have attached generated PDF for your kind reference as well. Would you please try using latest version of the API and in case you still face any issue, please let us know.
