Method Detail

getFrameBitmap

void getFrameBitmap(Continuation<? extends Consumer<Bitmap>> continuation)

Requests a single frame bitmap. Here's a brief example implementation using VuforiaLocalizer:

 @Override
 public void getFrameBitamp(Continuation<? extends Consumer<Bitmap>> continuation) {
     vuforia.getFrameOnce(Continuation.createTrivial(new Consumer<Frame>() {
         @Override
         public void accept(final Frame frame) {
             continuation.dispatch(new ContinuationResult<Consumer<Bitmap>>() {
                 @Override
                 public void handle(Consumer<Bitmap> consumer) {
                     consumer.accept(vuforia.convertFrameToBitmap(frame));
                 }
             });
         }
     }));
 }
 

Parameters:

continuation - frame bitmap consumer continuation
