Class SDLOverlay

java.lang.Object
  sdljava.video.SDLOverlay

public class SDLOverlay
extends java.lang.Object

A SDL_Overlay is similar to a SDL_Surface except it stores a YUV overlay. All the fields are read only, except for pixels which should be locked before use. The format field stores the format of the overlay which is one of the following:

 #define SDL_YV12_OVERLAY  0x32315659  // Planar mode: Y + V + U
 #define SDL_IYUV_OVERLAY  0x56555949  // Planar mode: Y + U + V
 #define SDL_YUY2_OVERLAY  0x32595559  // Packed mode: Y0+U0+Y1+V0
 #define SDL_UYVY_OVERLAY  0x59565955  // Packed mode: U0+Y0+V0+Y1
 #define SDL_YVYU_OVERLAY  0x55595659  // Packed mode: Y0+V0+Y1+U0
