  Really two part question…

  I’m drawing directly into a PDF from C# and it is working good except for a call to DrawImage. It throws an exception saying “Pdf document is closed: call Clear() to start a new one before adding any content.”

  This is the same document that I have been writing to and continue writing in. I call Clear() before writing anything into it. So message appears to be incorrect.

  I cant get past the writing of an image (logo) into my pdf so I tried to find a way to write an SVG image. Any suggestions?

  Hi Kevin,

  I’d recommend you to take a look at the product sample: ‘PdfSamples’ and refer the method ‘CreateDocumentImages’. This method draws string and image on a PDF instance.
  
  You can find the application installed here: \Documents\ComponentOne Samples\UWP\C1.UWP.Pdf\CS\PdfSamples

  Hope this helps.

  Hi Ruchir

  I couldn’t run the sample as the project is VS 2015. I didn’t take the time to try and sort it out to run in my environment VS-2019.

  Doesnt change the fact that all other DrawXXX commands work and DrawImage fails…

  Hi Kevin,

  I am not sure why the sample is not working for VS19 at your end, as I am running it with VS19 itself. Still, you can refer to sample code snippet using the following code: https://www.grapecity.com/componentone/docs/uwp/online-pdf/Adding_Images.html
  
  If the issue does not resolve, please share a demo app. demonstrating the problem. It will help us assist you accordingly in resolving the problem.
