PPT file format is a vivid and explicit way to present your stuff. Our Spire.Presentation enables you to manipulate PPT files easily and flexibly. Using Spire.Presentation you can generate, modify, convert, render, and print PPT documents without installing Microsoft PowerPoint on your machine. It also enables you to set the page size of PPT slide. Using Spire.Presentation, you can just set the page size with one line of code. Here is how to do so. Hope this document can be helpful for you.
Step 1: Create a PPT document.
Presentation presentation = new Presentation();
Step 2: Set page size type to "Custom".
presentation.SlideSize.Type = SlideSizeType.Custom;
You have to set this before you customize the size of slide.
Step 3: Set page size to (800, 500).
presentation.SlideSize.Size = new SizeF(800, 500);
Step 4: Set slide orientation to "Landscape".
presentation.SlideSize.Orientation = SlideOrienation.Landscape;
Step 5: Add background image and other context to the PPT document.
Step 6: Save the PPT document.
presentation.SaveToFile("PageProperty.pptx", FileFormat.Pptx2010);
Download and install Spire.Presentation for .NET and use below code to set the page size of slide.
