51  What is a Pixel Format

Each Vega Prime window uses a frame buffer, which is a collection of bitplane's storing the information about each pixel. The organization of these bitplane's defines the quality of the rendered images and is known as a Pixel Format. Pixel formats are made up from different Bitplane's which allocate for features such as:   colour information (RGB) Alpha (transparency) depth buffer(Z-bits) Samples Accumulation RGB Buffer Accumulation Alpha Buffer Stencil Buffer Mode (Single/Double(default))   Note that support for the various pixel format  configurations and combinations are not uniform across different Windows Graphics cards, Linux Systems and  Irix systems. Vega will ask the system for a bitplane specification supplied through the Lynx Windows panel settings or through code, the request may not be granted. When the notification level (in Systems panel) is set to Info or higher, messages tell the user which bitplane configuration is actually being used There are two methods of specifying bitplane configuration Vega.   The first is to request individual assignments in each bitplane category by selecting values for a collection of option menus The second method is to specify the value of the OpenGL Pixel Format  that contains a configuration acceptable to your applicati
