* Line placement flags, which control how candidates are generated for a linear feature.
enumclassLinePlacementFlag : int
OnLine = 1, //!< Labels can be placed directly over a line feature.
AboveLine = 2, //!< Labels can be placed above a line feature. Unless MapOrientation is also specified this mode respects the direction of the line feature, so a line from right to left labels will have labels placed placed below the line feature.
