Line placement flags, which control how candidates are generated for a linear feature.

Enumerator
OnLine	Labels can be placed directly over a line feature.
AboveLine	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.
BelowLine	Labels can be placed below 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 above the line feature.
MapOrientation	Signifies that the AboveLine and BelowLine flags should respect the map's orientation rather than the feature's orientation. For example, AboveLine will always result in label's being placed above a line, regardless of the line's direction.

Polygon placement flags, which control how candidates are generated for a polygon feature.

Enumerator
AllowPlacementOutsideOfPolygon	Labels can be placed outside of a polygon feature.
AllowPlacementInsideOfPolygon	Labels can be placed inside a polygon feature.
