ConvexHull2D

class pyopenms.ConvexHull2D

Bases: object

Cython implementation of _ConvexHull2D

__init__()

Methods

`__init__`	Cython signature: void ConvexHull2D()
`addPoint`	Cython signature: bool addPoint(DPosition2 point) Adds a point to the hull if it is not already contained.
`addPointXY`	Parameters: x (double) y (double)
`addPoints`	Cython signature: void addPoints(libcpp_vector[DPosition2] points) Adds points to the hull if it is not already contained.
`addPointsNPY`	Parameters: points (np.ndarray[np.float32_t, ndim=2])
`clear`	Cython signature: void clear() Removes all points
`compress`	Cython signature: size_t compress() Allows to reduce the disk/memory footprint of a hull
`encloses`	Cython signature: bool encloses(DPosition2) Returns if the point lies in the feature hull
`enclosesXY`	Parameters: x (float) y (float)
`expandToBoundingBox`	Cython signature: void expandToBoundingBox() Expand a convex hull to its bounding box.
`getBoundingBox`	Cython signature: DBoundingBox2 getBoundingBox() Returns the bounding box of the feature hull points
`getBoundingBox2D`	Returns: ((double,double),(double,double))
`getHullPoints`	Cython signature: libcpp_vector[DPosition2] getHullPoints() Accessor for the outer points
`getHullPointsNPY`	Returns: result (np.ndarray[np.float32_t, ndim=2])
`setHullPoints`	Cython signature: void setHullPoints(libcpp_vector[DPosition2]) Accessor for the outer(!) points (no checking is performed if this is actually a convex hull)
`setHullPointsNPY`	Parameters: points (np.ndarray[np.float32_t, ndim=2])

addPoint(): Cython signature: bool addPoint(DPosition2 point) Adds a point to the hull if it is not already contained. Returns if the point was added. This will trigger recomputation of the outer hull points (thus points set with setHullPoints() will be lost)

addPoints(): Cython signature: void addPoints(libcpp_vector[DPosition2] points) Adds points to the hull if it is not already contained. This will trigger recomputation of the outer hull points (thus points set with setHullPoints() will be lost)

compress(): Cython signature: size_t compress() Allows to reduce the disk/memory footprint of a hull

encloses(): Cython signature: bool encloses(DPosition2) Returns if the point lies in the feature hull

enclosesXY()

Parameters: x (float) y (float)

Returns: int

expandToBoundingBox(): Cython signature: void expandToBoundingBox() Expand a convex hull to its bounding box.

getBoundingBox(): Cython signature: DBoundingBox2 getBoundingBox() Returns the bounding box of the feature hull points

getHullPoints(): Cython signature: libcpp_vector[DPosition2] getHullPoints() Accessor for the outer points

setHullPoints(): Cython signature: void setHullPoints(libcpp_vector[DPosition2]) Accessor for the outer(!) points (no checking is performed if this is actually a convex hull)
