Due to internal optimizations, there are certain restrictions on using Arc: - The arc cannot be filled. - The arc must be used in an :class:`~.axes.Axes` instance---it can not be added directly to a `.Figure`---because it is optimized to only render the segments that are inside the axes bounding box with high resolution. c C s4 | j d | j d | j| j| j| j| jf}d}|| S )Nr r zEArc(xy=(%g, %g), width=%g, height=%g, angle=%g, theta1=%g, theta2=%g))r/ r� r� r� r1 r2 r� r> r> r? r� 0 s �z Arc.__str__r� � �v@c K s> |� dd�}|rtd��tj| ||||f|� || _|| _dS )a� Parameters ---------- xy : (float, float) The center of the ellipse. width : float The length of the horizontal axis. height : float The length of the vertical axis. angle : float Rotation of the ellipse in degrees (counterclockwise). theta1, theta2 : float, optional Starting and ending angles of the arc in degrees. These values are relative to *angle*, e.g. if *angle* = 45 and *theta1* = 90 the absolute starting angle is 135. Default *theta1* = 0, *theta2* = 360, i.e. a complete ellipse. The arc is drawn in the counterclockwise direction.

Notes ----- Ellipses are normally drawn using an approximation that uses eight cubic Bezier splines. The error of this approximation is 1.89818e-6, according to this unverified source: Lancaster, Don. *Approximating a Circle or an Ellipse Using Four Bezier Cubic Splines.* http://www.tinaja.com/glib/ellipse4.pdf There is a use case where very large ellipses must be drawn with very high accuracy, and it is too expensive to render the entire ellipse with enough segments (either splines or line segments). Therefore, in the case where either radius of the ellipse is large enough that the error of the spline approximation will be visible (greater than one pixel offset from the ideal), a different technique is used. In that case, only the visible parts of the ellipse are drawn, with each visible arc using a fixed number of spline segments (8). The algorithm proceeds as follows: 1. The points where the ellipse intersects the axes bounding box are located. (This is done be performing an inverse transformation on the axes bbox such that it is relative to the unit circle -- this makes the intersection calculation much easier than doing rotated ellipse intersection directly). This uses the "line intersecting a circle" algorithm from: Vince, John. *Geometry for Computer Graphics: Formulae, Examples & Proofs.* London: Springer-Verlag, 2005. 2. The angles of each of the intersection points are calculated. 3. Proceeding counterclockwise starting in the positive x-direction, each of the visible arc-segments between the pairs of vertices are drawn using the Bezier arc approximation technique implemented in :meth:`matplotlib.path.Path.arc`. �axesz'Arcs can only be used in Axes instancesc S s4 t �| �} t �| �}t �| �}t �t �|| |��S rL )rV �deg2rad�cos�sin�rad2degZarctan2)�thetar rN rO r> r> r? � theta_stretch� s z Arc.draw.<locals>.theta_stretchg�\!��Ac s s� || }|| }|| || }| | || }|| }|| } | dkrn|| | } | | | } | | fV nt| dkr�|dk r�d} nd} t �| �} dD ]J}|| || | | | } | | |t �|� | | } | | fV q�d S )Nr� rl rD )rD rl )rV rn r7 )r� r� r� r� rH rI Zdr2�DZD2ZdiscrimrN rO Zsign_dyZ sqrt_discrimZsignr> r> r? � iter_circle_intersect_on_line� s& z/Arc.draw.<locals>.iter_circle_intersect_on_linec 3 s� d}|| k r|| }}n | | }}||k r6|| }}n || }}||8 }||8 }||7 }||7 }� | |||�D ]B\} } || kr�|krnn qn|| kr�|krnn qn| | fV qnd S )Ng��&� .>r> ) r� r� r� r� �epsilonZx0eZx1eZy0eZy1erN rO �r� r> r? �!iter_circle_intersect_on_line_seg� s 0z3Arc.draw.<locals>.iter_circle_intersect_on_line_segNr( r r r) � FT)$�hasattr� RuntimeErrorrt r� r� r� r� r1 r2 r@ �transform_pointr r9 r r r� r� r r� ry r� �invertedZ transformed�set�ziprU rV ZarccosZpir} �add�sortedrz rM r{ r| )r9 r� r� r� r r1 r2 Z inv_errorr� Zbox_pathZbox_path_transformZthetasZp0Zp1r� r� r� r� rN rO r~ Z last_thetaZ theta1_radr\ Z path_originalr> r� r? r� f s\ 2 � & � zArc.drawN)r� r� rw ) r� r� r� r� r� r r� r% r r� r� r> r> r> r? r� $ s � .r� Tc C s� |dkr i }|� � }|�dd�}|�|�}| �|�}|j\}}}} ||d 8 }||d 8 }||7 }| |7 } t||f|| |d�} | �t�� � | � d� | � |� | � |� dS )ad This is a debug function to draw a rectangle around the bounding box returned by :meth:`~matplotlib.artist.Artist.get_window_extent` of an artist, to test whether the artist is returning the correct bbox. *props* is a dict of rectangle props with the additional property 'pad' that sets the padding around the bbox in points.

A style object can be created as:: BoxStyle.Round(pad=0.2) or:: BoxStyle("Round", pad=0.2) or:: BoxStyle("Round, pad=0.2") Following boxstyle classes are defined. %(AvailableBoxstyles)s An instance of any boxstyle class is an callable object, whose call signature is:: __call__(self, x0, y0, width, height, mutation_size, aspect_ratio=1.) and returns a :class:`Path` instance. *x0*, *y0*, *width* and *height* specify the location and size of the box to be drawn. *mutation_scale* determines the overall size of the mutation (by which I mean the transformation of the rectangle to the fancy box). *mutation_aspect* determines the aspect-ratio of the mutation. c @ s" e Zd ZdZdd� Zddd�ZdS ) zBoxStyle._Basea_ :class:`BBoxTransmuterBase` and its derivatives are used to make a fancy box around a given rectangle. The :meth:`__call__` method returns the :class:`~matplotlib.path.Path` of the fancy box. This class is not an artist and actual drawing of the fancy box is done by the :class:`FancyBboxPatch` class. c C s t d��dS )a� The transmute method is a very core of the :class:`BboxTransmuter` class and must be overridden in the subclasses. It receives the location and size of the rectangle, and the mutation_size, with which the amount of padding and etc. will be scaled.

These are mainly used with :class:`FancyArrowPatch`. A arrowstyle object can be either created as:: ArrowStyle.Fancy(head_length=.4, head_width=.4, tail_width=.4) or:: ArrowStyle("Fancy", head_length=.4, head_width=.4, tail_width=.4) or:: ArrowStyle("Fancy, head_length=.4, head_width=.4, tail_width=.4") The following classes are defined %(AvailableArrowstyles)s An instance of any arrow style class is a callable object, whose call signature is:: __call__(self, path, mutation_size, linewidth, aspect_ratio=1.) and it returns a tuple of a :class:`Path` instance and a boolean value. *path* is a :class:`Path` instance along which the arrow will be drawn. *mutation_size* and *aspect_ratio* have the same meaning as in :class:`BoxStyle`. *linewidth* is a line width to be stroked. This is meant to be used to correct the location of the head so that it does not overshoot the destination point, but not all classes support it. c @ s. e Zd ZdZedd� �Zdd� Zd dd�Zd S ) zArrowStyle._Basea� Arrow Transmuter Base class ArrowTransmuterBase and its derivatives are used to make a fancy arrow around a given path. The __call__ method returns a path (which will be used to create a PathPatch instance) and a boolean value indicating the path is open therefore is not fillable.

It receives the path object along which the arrow will be drawn, and the mutation_size, with which the arrow head etc. will be scaled. The linewidth may be used to adjust the path so that it does not pass beyond the given points. It returns a tuple of a Path instance and a boolean. The boolean value indicate whether the path can be filled or not. The return value can also be a list of paths and list of booleans of a same length. r� Nr� )r9 rC r� r r> r> r? r� � s zArrowStyle._Base.transmuterD c C s� t |�}|dk r�|jdd� |jdd� }}|dd�df | |dd�df< t||�}| �|||�\}} t�| �r�g } t|�D ]B} | j| j } } | dd�df | | dd�df< | �t| | �� q�| | fS || fS n| �|||�S dS )z� The __call__ method is a thin wrapper around the transmute method and takes care of the aspect ratio.
