Microsoft DirectCompute is an application programming interface (API) that supports running compute kernels on general-purpose computing on graphics processing units on Microsoft's Windows Vista, Windows 7 and later versions.
A COM object can be created without type library information; with only a path to the DLL file and CLSID. A client can use the COM DLL function DllGetClassObject with the CLSID and IID_IClassFactory to create an instance of a factory object. The client can then use the factory object's CreateInstance to create an instance. [19]
In GDI, a device context (DC) defines the attributes of text and images for the output device, e.g., screen or printer. GDI maintains the actual context. Generating the output requires a handle to the device context (HDC). After generating the output, the handle could be released. GDI uses Bresenham's line drawing algorithm to draw aliased lines.

A profile is a set of APIs that support devices with different capabilities and resources within the CDC framework to provide a complete Java application environment. Three profiles are available, which build on each other incrementally and allow application developers to choose the appropriate programming model for a particular device.
DirectX back-end; older SDL 1.2 uses DirectX 7 by default, while 2.0 defaults to DirectX 9 and can access up to DirectX 12. Quartz back-end for macOS (dropped in 2.0). Metal back-end for macOS / iOS / tvOS since 2.0.8; older versions use OpenGL by default. [54] [55] Xlib back-end for X11-based windowing system on various operating systems. [56]
Direct2D [1] is a 2D vector graphics application programming interface (API) designed by Microsoft and implemented in Windows 10, [2] Windows 8, Windows 7 and Windows Server 2008 R2, and also Windows Vista and Windows Server 2008 (with Platform Update installed).
DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU -intensive operations such as iDCT , motion compensation and deinterlacing to be offloaded to the GPU .
