ID2D1DeviceContext interface (d2d1_1.h)
Represents a set of state and command buffers that are used to render to a target.
The device context can render to a target bitmap or a command list.
Inheritance
The ID2D1DeviceContext interface inherits from ID2D1RenderTarget. ID2D1DeviceContext also has these types of members:
