| SE_shape_generate_buffer | |
Generates a buffer around the source shape, and returns the resulting new shape.
LONG SE_shape_generate_buffer (const SE_SHAPE src_shape, LFLOAT distance, LONG max_pts, SE_SHAPE tgt_shape);
| src_shape | A handle to an active shape object |
| distance | The buffer distance |
| max_pts | The maximum number of points allowed in the new shape |
| tgt_shape | A handle to an active shape object, returned as the new shape |
Generates a buffer around the source shape, returning the resulting new shape as tgt_shape. Negative buffer distances are supported for area shapes only. If the source shape is not an area shape, the absolute value of the buffer distance is used. An SE_INVALID_NUMBER_OF_POINTS error will occur if the target shape is not large enough to hold the resulting buffer. In this case, increase the allocated size of the target shape.

• 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.
• If the max_pts argument isn't large enough to accomodate the resulting shape, it will return SE_INVALID_NUMBER_OF_POINTS.
