| SE_shape_generate_polygon | |
Generates a polygon shape from an array of points.
LONG SE_shape_generate_polygon (LONG num_pts, LONG num_parts, LONG *part_offsets, SE_POINT *point_array, LFLOAT *z, LFLOAT *measure, SE_SHAPE tgt_shape);
| num_pts | The number of points to generate the polygon shape from |
| num_parts | The number of parts contained in the point array |
| part_offsets | An array of indices into the point_array delineating each shape part. This may be NULL if num_parts is 1. |
| point_array | The array of x,y coordinates |
| z | The array of z-coordinates, if needed |
| measure | A pointer to the measures, if needed |
| tgt_shape | A handle to an active shape object, returned as the new polygon shape |
Generates a polygon shape from an array of points. If the z or measure array values are null, the resulting shape won’t contain elevations or measures.

• If you pass a shape returned from SE_stable_search or SE_stable_get_shape to ‘tgt_shape’, the SE_READ_ONLY_SHAPE error is returned.
• Ignores any CAD data in the source shape, and removes any CAD data in the target shape.
