bezier package¶
Helper for Bézier Curves, Triangles, and Higher Order Objects.
Intended to perform basic operations on Bézier objects such as intersections, length/area/etc. computations, subdivision, implicitization and other relevant information.
Plotting utilities are also provided.

class
bezier.
UnsupportedDegree
(degree, supported=())¶ Custom exception to indicate the given degree is unsupported.
This is intentionally a subclass of a
NotImplementedError
since it’s intended to indicate a lack of an implementation. For example,Curve.reduce_()
uses hard-coded matrices for a small subset of possible degrees, so the implementation is degree-specific:>>> degree = 5 >>> nodes = np.empty((2, degree + 1), order='F') >>> curve = bezier.Curve(nodes, degree=degree) >>> curve.reduce_() Traceback (most recent call last): ... bezier._helpers.UnsupportedDegree: The only degrees supported at this time are 1, 2, 3 and 4 (degree=5)
Parameters: -
degree
= None¶ int – The degree that the caller attempted to use.

get_include
()¶ Get the directory with
.h
header files.Extension modules (and Cython modules) that need to compile against
libbezier
should use this function to locate the appropriate include directory.For more information, see Native Libraries.
Returns: include
directory that contains header files for thelibbezier
Fortran library.Return type: str
-
bezier.
get_lib
()¶ Get the directory with
.a
/.lib
static libraries.Extension modules (and Cython modules) that need to compile against
libbezier
should use this function to locate the appropriate lib directory.For more information, see Native Libraries.
Returns: lib
directory that contains static libraries for thelibbezier
Fortran library.Return type: str
-
bezier.
get_dll
()¶ Get the directory with the Windows shared library.
Extension modules (and Cython modules) that need to compile against
libbezier
should use this function to locate the appropriate Windows shared library or libraries (DLLs).For more information, see Native Libraries.
Returns: extra-dll
directory that contains the Windows shared library for thelibbezier
Fortran library.Return type: str Raises: OSError
– If this function is used anywhere other than Windows.
