@brief Win32 screencap method
No bitwise OR, select ONE method only.
No default value. Client should choose one as default.
Different applications use different rendering methods, there is no universal solution.
| Method | Speed | Compatibility | Require Admin | Background Support | Notes |
|---|---|---|---|---|---|
| GDI | Fast | Medium | No | No | |
| FramePool | Very Fast | Medium | No | Yes | Requires Windows 10 1903+ |
| DXGI_DesktopDup | Very Fast | Low | No | No | Desktop duplication (full screen) |
| DXGI_DesktopDup_Window | Very Fast | Low | No | No | Desktop duplication then crop |
| PrintWindow | Medium | Medium | No | Yes | |
| ScreenDC | Fast | High | No | No |
Note: FramePool and PrintWindow support pseudo-minimize — when the target window is minimized, they make it transparent and click-through, then restore it without activation, allowing screencap to continue without disturbing the user. Other screencap methods will fail when the target window is minimized.
