Without this, the image\ndata is transparent, and while running - it appears as if no image is\npresented.\n\nKieran Bingham (3):\n qcam: viewfinder_qt: Fix include orders\n qcam: format_converter: Support X RGB variants\n qcam: viewfinder_qt: Support X RGB variants\n\n src/qcam/format_converter.cpp | 4 ++++\n src/qcam/viewfinder_qt.cpp | 9 ++++++---\n 2 files changed, 10 insertions(+), 3 deletions(-)" }
