# .NET Window Capture Samples
> NOTE: This is an experimental project. Please use it at your own risk.
Captures a window or desktop screen and renders it in WPF or DirectX.
## System Requirements
- Windows 10 (64-bit, April 2018 Update)
- DirectX 11
- .NET Framework 4.7.2
- Visual Studio 2019
## Capture Methods
| Project Name | Minimal Windows Version | Render To | Platform |
| -------------------------- | ----------------------- | --------- | -------- |
| `Win32.BitBlt` | Windows 95 | DirectX | Win32 |
| `Win32.DesktopDuplication` | Windows 8 | DirectX | Win32 |
| `Win32.DwmSharedSurface` | Windows 7 | DirectX | Win32 |
| `Win32.DwmThumbnail` | Windows 7 | WPF | Win32 |
| `WinRT.GraphicsCapture` | Windows 10 1803 | DirectX | WinRT |
## Comparison
### Compare with capture target
| Capture Method | Window Capture | Desktop Capture | Outside of Desktop | HW Acceleration | DirectX Games |
| -------------------------- | :------------: | :-------------: | :----------------: | :-------------: | :-----------: |
| `Win32.BitBlt` | Yes | Yes | Yes | No | Yes |
| `Win32.DesktopDuplication` | No | Yes | No | Yes | Yes |
| `Win32.DwmSharedSurface` | Yes | No | Yes | No | Yes |
| `Win32.DwmThumbnail` | Yes | No | Yes | Yes | Yes |
| `WinRT.GraphicsCapture` | Yes | Yes | Yes | Yes | Yes |
- `Games` is checked using [Märchen Forest](https://anemonecoronaria.sakura.ne.jp/merufore/).
### Compare with capture source
| Capture Method | Window Handle | Monitor Handle | Another |
| -------------------------- | :-----------: | :------------: | :--------------: |
| `Win32.BitBlt` | Yes | No | - |
| `Win32.DesktopDuplication` | No | No | Device (Monitor) |
| `Win32.DwmSharedSurface` | Yes | No | - |
| `Win32.DwmThumbnail` | Yes | No | - |
| `WinRT.GraphicsCapture` | Yes \* | Yes \* | Embedded Picker |
- \*: Require Windows 10 1903 or greater.
### Compare with delay
| Capture Method | Delay (ms) |
| -------------------------- | :--------: |
| `Win32.BitBlt` | ~ 20ms |
| `Win32.DesktopDuplication` | N/A |
| `Win32.DwmSharedSurface` | ~ 20ms |
| `Win32.DwmThumbnail` | **0ms** |
| `WinRT.GraphicsCapture` | ~ 40ms |
- I used [this video](https://www.youtube.com/watch?v=rf2Lmfqi5ZM) to investigate the delay.
- It is just a reference value, but it is certain that the delay of `Win32.DwmThumbnail` is 0 ms.
- This is because it uses a drawing method that is entirely common to other windows.
