Examples with ImageProxy androidx.camera.core.ImageProxy used on opensource projects

Example 1 with ImageProxy

use of androidx.camera.core.ImageProxy in project Signal-Android by signalapp.

the class CameraXFragment method onCaptureClicked.

private void onCaptureClicked() {
    Stopwatch stopwatch = new Stopwatch("Capture");
    CameraXSelfieFlashHelper flashHelper = new CameraXSelfieFlashHelper(requireActivity().getWindow(), camera, selfieFlash);
    camera.takePicture(Executors.mainThreadExecutor(), new ImageCapture.OnImageCapturedCallback() {

        @Override
        public void onCaptureSuccess(@NonNull ImageProxy image) {
            flashHelper.endFlash();
            SimpleTask.run(CameraXFragment.this.getViewLifecycleOwner().getLifecycle(), () -> {
                stopwatch.split("captured");
                try {
                    return CameraXUtil.toJpeg(image, camera.getCameraLensFacing() == CameraSelector.LENS_FACING_FRONT);
                } catch (IOException e) {
                    Log.w(TAG, "Failed to encode captured image.", e);
                    return null;
                } finally {
                    image.close();
                }
            }, result -> {
                stopwatch.split("transformed");
                stopwatch.stop(TAG);
                if (result != null) {
                    controller.onImageCaptured(result.getData(), result.getWidth(), result.getHeight());
                } else {
                    controller.onCameraError();
                }
            });
        }

        @Override
        public void onError(ImageCaptureException exception) {
            Log.w(TAG, "Failed to capture image", exception);
            flashHelper.endFlash();
            controller.onCameraError();
        }
    });
    flashHelper.startFlash();
