GDI Interoperation (Windows Embedded CE 6.0)
1/6/2010
Microsoft® Direct3D Mobile® only allows for GDI Interoperation on lockable RGB surfaces. The IDirect3DMobileSurface interface contains methods to retrieve and release handles to a GDI Device Context (HDC) that are useable in any GDI function.
The surface will be locked, for the entire time that the device context is held. This implies that it is only possible to get a device context to a surface that the driver allows to be locked and that no other rendering routines may be used on the surface while the DC is being held.
