module documentation

Utility classes for drawing routines.

Class BoundingBox Class representing a bounding box (a rectangular area) that encloses some objects.
Class FakeModule Fake module that raises an exception for everything
Class Point Class representing a point on the 2D plane.
Class Rectangle Class representing a rectangle.
Function evaluate_cubic_bezier_curve Evaluates the Bezier curve from point (x0,y0) to (x3,y3) via control points (x1,y1) and (x2,y2) with parameter t.
Function find_cairo Tries to import the cairo Python module if it is installed, also trying cairocffi (a drop-in replacement of cairo). Returns a fake module if everything fails.
Function find_matplotlib Tries to import the matplotlib Python module if it is installed. Returns a fake module if everything fails.
Function get_bezier_control_points_for_curved_edge Helper function that calculates the Bezier control points for a curved edge that goes from (x1, y1) to (x2, y2).
def evaluate_cubic_bezier_curve(x0, y0, x1, y1, x2, y2, x3, y3, t):

Evaluates the Bezier curve from point (x0,y0) to (x3,y3) via control points (x1,y1) and (x2,y2) with parameter t.

def find_cairo():

Tries to import the cairo Python module if it is installed, also trying cairocffi (a drop-in replacement of cairo). Returns a fake module if everything fails.

def find_matplotlib():

Tries to import the matplotlib Python module if it is installed. Returns a fake module if everything fails.

def get_bezier_control_points_for_curved_edge(x1, y1, x2, y2, curvature):

Helper function that calculates the Bezier control points for a curved edge that goes from (x1, y1) to (x2, y2).
