Notable changes

  • Graphics library: In .NET Framework, our library makes use of System.Drawing.Common for any text measuring and graphics-related operations. Whereas in .NET Core, our library uses the SkiaSharp graphics library to provide the same type of graphics.
  • The below features are make use of SkiaSharp graphics library, which are separated into a separate package, Syncfusion.PresentationRenderer.Net.Core
  • During PowerPoint Presentation to PDF/Image conversion, if you are facing font-related problems (like accessing font from the environment), you can pass the fonts as streams using our font substitution approach.
