Import PDF Pages into Slides

Create a two-page PDF fixture, import its pages, and save an editable presentation container. The default empty slide is removed before import. Imported object editability depends on the PDF content and reconstruction; this is not a promise to restore the original PowerPoint object model or exact formatting.

Run the example

Download the complete project. It includes all source, SDK settings and locked NuGet dependencies. The code creates its own four-slide input with a hidden slide, speaker notes, a table, chart and picture.

These projects were tested on Windows x64 with Arial and the .NET SDK 8.0.427 pinned by global.json. Their synthetic picture generator uses System.Drawing on Windows. For a separately tested Linux environment, see the Docker converter. Restore the pinned Aspose.Slides.NET package and set ASPOSE_LICENSE_PATH to your license file for unrestricted results; evaluation mode adds a watermark and limits extracted text. See installation and licensing.

dotnet run --project Example.csproj --configuration Release

Expected result

The program writes “input.pdf”, “imported.pptx”, “imported-1.png”, “imported-2.png” beside the project, plus the synthetic source.pptx and a result.json summary. Inspect the rendered/exported files with the viewer appropriate to the format. Input generation is visible in CreateSource; replace it with opening your own presentation when adapting the example.
