C++ (Cpp) ApplyCallbackTransform Examples

Example #1

File: APZCCallbackHelper.cpp Project: CodeSpeaker/gecko-dev

nsIntPoint
APZCCallbackHelper::ApplyCallbackTransform(const nsIntPoint& aPoint,
                                        const ScrollableLayerGuid& aGuid,
                                        const CSSToLayoutDeviceScale& aScale)
{
    LayoutDevicePoint point = LayoutDevicePoint(aPoint.x, aPoint.y);
    point = ApplyCallbackTransform(point / aScale, aGuid) * aScale;
    LayoutDeviceIntPoint ret = gfx::RoundedToInt(point);
    return nsIntPoint(ret.x, ret.y);
}

Example #2

LayoutDeviceIntPoint
APZCCallbackHelper::ApplyCallbackTransform(const LayoutDeviceIntPoint& aPoint,
                                           const ScrollableLayerGuid& aGuid,

    point = ApplyCallbackTransform(point / aScale, aGuid, aPresShellResolution) * aScale;
    return gfx::RoundedToInt(point);
}
