CGMax is designed for use on the Microsoft Win32 platform. Along with the Blackmagic DeckLink supporting libraries, the application uses a number of Microsoft technologies to provide powerful and reliable character generating capabilities. Microsoft Windows provides a powerful and reliable 32-bit platform for working with Graphics and Multimedia, along with a number of supporting technologies from Microsoft, which makes it an ideal platform for developing CGMax.
BlackMagic DeckLink Libraries
The DeckLink libraries are a framework produced by Blackmagic design for working with the Blackmagic Decklink series. These libraries provide software developers with a flexible interface for exploiting the powerful capabilities of the Blackmagic DeckLink card series.

GDI Plus is the successor of of GDI.It is an improved 2D graphics environment.GDI Plus offers enhanced graphics capabilities such as alpha blending ,antialiasing,texturing
Interpolation works by using known data to estimate values at unknown points.Interpolation is a method to increase of decrease a number of pixels in an image.For scaling images several algorithms can be used.Depending on the sophistication of the algorithm ,resulting image quality is changed.
Video is a sequence of still images of a certain scene. The number of still images taken per second should be a considerable amount, in order to get a smoothly running video. Video technology is the key area in the television industry.
Alpha blending is the process of superimposing an image over another image to create the appearance of partial transparency. Alpha blending is used extensively by character generators when superimposing characters over the live video.
