I use Open XML SDK tool to parse pptx-files. Now I am going to develop my own .NET library/tool to generate an image from a PowerPoint slide. Open XML SDK in principle is not for such tasks, and I do not know where to start research?.

  • maybe to solve it better to use another programming language, for example, C++ (I also know it) with some library?
  • or it may be necessary intermediate convert pptx into some another format, for example, HTML and only then to image?

I also tried to investigate Aspose.Slides and Spire.Presentation libraries' dependencies in NuGet to know what they use to an image generation, but these attempts did not succeed.

This looks like a good starting point: Presentation to image conversion The cited versions are old, but the syntax is still the same: PPT slides to images

  • Topics which you specified describe creating an image via Syncfusion and Interop.PowerPoint libraries. These tools are like Aspose and Spire, which I above-mentioned. I am interesting a little bit **low** thinks: which algorithms and tools these libraries use. – Adam Shakhabov Jul 18 '19 at 12:28

My mistake, I misunderstood the end goal.

  • Maybe I misunderstood, but actually, I already use reverse engineering during entire research pptx-file. But have not idea how to use it for my problem. You talked about _"... a known image in PowerPoint you've already parsed"_. I want to remind you that I am trying to save **whole slide layout in an image file**, instead parse separate picture elements. Can you give more information about what you mentioned. – Adam Shakhabov Jul 18 '19 at 20:04
