public class SDLOverlay

extends java.lang.Object

a YUV video overlay

From SDL Library Documentation, SDL API Reference, SDL_Overlay

 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: 

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

More information on YUV formats can be found at http://www.webartz.com/fourcc/indexyuv.htm.

lock

public boolean lock()

unlock

public boolean unlock()

display

public boolean display(SDLRect rect)

Blit the overlay to the surface specified when it was created. The SDLRect object, rect, specifies the position and size of the destination. If the rect is a larger or smaller than the overlay then the overlay will be scaled, this is optimized for 2x scaling.

display

public boolean display(int x,
                       int y,
                       int w,
                       int h)
