2.3 Overlay Manager

  • On-the-Fly Composition enables alpha blending on up to 4 input pipelines
  • Transparency color key (source and destination)
  • Alpha blending support: Embedded pixel alpha (ARGB and RGBA), global pixel, and combination of global pixel and pixel alpha
  • Z-order programmable (full flexibility)
  • Color Processing per pipe supports gamma correction, color space conversion, BCHS control, output dithering, scaling
