Shows how to use Direct2D to draw and manipulate SVG images programmatically.
Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.
Specifically, this sample shows how to:
- Load an SVG image from the app package and parse it with Direct2D.
- Use Direct2D's SVG object model APIs to programmatically walk the SVG tree and read/write SVG attributes.
- Render an SVG document parsed by Direct2D.
The sample's project files fall into the following categories.
The following files form the main educational content of the sample:
- DirectXPage.xaml/.cpp/.h/: Implements a XAML-based UI to drive the app. Hosts the DirectX content in a SwapChainPanel.
- App.xaml/.cpp/.h: The app's main entry point.
- D2DSvgImageRenderer.cpp/.h: The core implementation of the Direct2D scene.
The following files provide common functionality needed by DirectX SDK samples:
- DeviceResources.cpp/.h: Manages creation and lifetime of the core Direct3D and Direct2D device-dependent resources. Handles cases such as device lost and window size and orientation changes.
- DirectXHelper.h: Common inline helper functions, including ThrowIfFailed which converts HRESULT-based APIs into an exception model.
All DirectX SDK samples and the Visual Studio template DirectX projects contain a version of these files. These common files demonstrate important best practices for DirectX UWP apps, and you are encouraged to use them in your own projects.
Variants of the following files are found in every UWP app written in C++:
- Package.appxmanifest
- pch.cpp/.h
- D2DSvgImageRenderer.vcxproj
- D2DSvgImageRenderer.vcxproj.filters
- D2DSvgImageRenderer.sln

- If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
- Start Microsoft Visual Studio and select File > Open > Project/Solution.
- Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio Solution (.sln) file.
- Press Ctrl+Shift+B, or select Build > Build Solution.
The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.
- Select Build > Deploy Solution.
- To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or selectDebug > Start Without Debugging.
