Version 2019 R2 - September 23, 2019
- PDF Engine
- A newly designed PDF engine is introduced that works across platforms. Since this engine is not yet at parity with the feature-set of the old PDF engine, it is enabled only for .NET Standard. So it is used by the new Xamarin document viewer control and also can be used in .NET Core / .NET Core 3 frameworks. Once its feature-set matches that of the old PDF engine, the old engine will be replaced with the new one for all platforms.
- Features currently supported by the new PDF engine
- Shapes
- Text
- Supported font types: Type 1, TrueType, CFF, CID
- Images
- Supported image types: 8 BPC BMP and 8 BPC JPEG

- Stream decompression filter types:
- Flate
