long overrideDefaultAnnoAlignment(int vertEnum, in horzEnum)

This method changes the current vertical and horizontal placement enumerations for the layer to vertEnum and horzEnum, repsectively. Valid values for vertEnum are: 0, 1, or 2, corresponding to above, centered, and below, respectively.  Valid values for horzEnum are: 0, 1, or 2, corresponding to left, centered, and right, respectively.  Based on these assignments, the text is placed in any of nine possible positions, relative to the target. These nine positions are:

The target position to which these offsets apply depends upon the layer type, as follows:

The alignment defined via this method will be used during all subsequent calls to doAnnotation for this layer.

This method returns zero upon success, and returns an error code if either of the arguments are invalid.
