set_use_caps¶
- pydl.pydlutils.mangle.set_use_caps(polygon, index_list, add=False, tol=1e-10, allow_doubles=False, allow_neg_doubles=False)[source]¶
Set the bits in use_caps for a polygon.
- Parameters:
- polygon
ManglePolygon
A polygon object.
- index_listarray-like
A list of indices of caps to set in the polygon. Should be no longer, nor contain indices greater than the number of caps (
polygon.ncaps
).- add
bool
, optional If
True
, don’t initialize the use_caps value to zero, use the existing value associated withpolygon
instead.- tol
float
, optional Tolerance used to determine whether two caps are identical.
- allow_doubles
bool
, optional Normally, this routine automatically sets use_caps such that no two caps with use_caps set are identical.
- allow_neg_doubles
bool
, optional Normally, two caps that are identical except for the sign of
cm
would be set unused. This inhibits that behaviour.
- polygon
- Returns:
int
Value of use_caps.
