Graphics Composition Concepts

This section covers some important graphics composition topics, such as scene elements (sometimes known as layers) and surfaces.

Target audience: Device creators.

• Scene Elements
  This topic provides an introduction to the concept of scene elements within the context of graphics composition. Scene elements are sometimes referred to as layers.
• Surfaces
  This topic provides an introduction to graphics composition surfaces, which are usually simply called surfaces. Surfaces are pixel buffers that have associated metadata describing the width, height, stride and pixel format and are used as input to the composition components. Surfaces can be multi-buffered and are identified by a 128-bit identifier (called the surface ID).
