Struct CaptureScreen 

Source 
pub struct CaptureScreen(pub MemoryRange);
Expand description

Captures the current composited screen contents as raw pixel data.

On hardware the byte order is BGRA8888; on the simulator it is RGBA8888. Caller allocates a MemoryRange of SCREEN_WIDTH * SCREEN_HEIGHT * 4 bytes, lends it mutable to gui-server, which fills it with the composited pixel data.
