This module provides a single :class:`FontManager` instance that can be shared across backends and platforms. The :func:`findfont` function returns the best TrueType (TTF) font file in the local or system font path that matches the specified :class:`FontProperties` instance. The :class:`FontManager` also handles Adobe Font Metrics (AFM) font files for use by the PostScript backend. The design is based on the `W3C Cascading Style Sheet, Level 1 (CSS1) font specification <http://www.w3.org/TR/1998/REC-CSS2-19980512/>`_. Future versions may implement the Level 2 or 2.1 specifications. � )� lru_cacheN)�Number)�Path)�Timer)�afm�cbook�ft2font�rcParams)�parse_fontconfig_pattern�generate_fontconfig_patterng�I +��?gh��|?5�?g-����?� �?g333333�?g ףp= �?g��S�?) zxx-smallzx-smallZsmall�mediumZlargezx-largezxx-largeZlargerZsmallerN�d �� i, � �� iX � i i� ) zultra-condensedzextra-condensed� condensed�semi-condensed�normalz semi-expanded�expandedzextra-expandedzultra-expanded)Z ultralightZlightr �regularZbookr ZromanZsemiboldZdemiboldZdemiZboldZheavyz extra boldZblackZserif� sans-serif� sans serifZcursiveZfantasyZ monospace�sansz@Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Foldersz2SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fontsz/SOFTWARE\Microsoft\Windows\CurrentVersion\Fontsz%AppData\Local\Microsoft\Windows\Fontsz'AppData\Roaming\Microsoft\Windows\Fontsz /usr/X11R6/lib/X11/fonts/TTF/z/usr/X11/lib/X11/fontsz/usr/share/fonts/z/usr/local/share/fonts/z)/usr/lib/openoffice/share/fonts/truetype/Z XDG_DATA_HOMEz .local/share�fontsz.fontsz/Library/Fonts/z/Network/Library/Fonts/z/System/Library/Fonts/z/opt/local/share/fontsz Library/Fontsc C s& dgdddgdddgdddgd�| S )zs Return a list of file extensions extensions that are synonyms for the given file extension *fileext*. r �otf�ttc�ttf)r r r r � ��fontextr r �9/usr/lib/python3/dist-packages/matplotlib/font_manager.py�get_fontext_synonyms� s ��r# c s& dd� � D �� � fdd�t �| �D �S )zo Return a list of all fonts matching any of the extensions, found recursively under the directory. c S s g | ] }d | �qS ��.r ��.0�extr r r" � <listcomp>� s z list_fonts.<locals>.<listcomp>c s< g | ]4\}}}|D ]$}t |�j�� � krtj�||��qqS r )r �suffix�lower�os�path�join)r' �dirpath�_� filenames�filename�� extensionsr r" r) � s �)r, �walk)� directoryr4 r r3 r" � list_fonts� s �r7 c C sn ddl } z8| �| jt�� }| �|d�d W 5 Q R � W S Q R X W n( tk rh tj�tj d d� Y S X dS )a Return the user-specified font directory for Win32.

The font properties are those described in the `W3C Cascading Style Sheet, Level 1 <http://www.w3.org/TR/1998/REC-CSS2-19980512/>`_ font specification. The six properties are: - family: A list of font names in decreasing order of priority. The items may include a generic font family name, either 'serif', 'sans-serif', 'cursive', 'fantasy', or 'monospace'. In that case, the actual font to be used will be looked up from the associated rcParam. - style: Either 'normal', 'italic' or 'oblique'. - variant: Either 'normal' or 'small-caps'. - stretch: A numeric value in the range 0-1000 or one of 'ultra-condensed', 'extra-condensed', 'condensed', 'semi-condensed', 'normal', 'semi-expanded', 'expanded', 'extra-expanded' or 'ultra-expanded' - weight: A numeric value in the range 0-1000 or one of 'ultralight', 'light', 'normal', 'regular', 'book', 'medium', 'roman', 'semibold', 'demibold', 'demi', 'bold', 'heavy', 'extra bold', 'black' - size: Either an relative value of 'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', 'xx-large' or an absolute font size, e.g., 12 The default font property for TrueType fonts (as specified in the default rcParams) is:: sans-serif, normal, normal, normal, normal, scalable. Alternatively, a font may be specified using an absolute path to a .ttf file, by using the *fname* kwarg. The preferred usage of font sizes is to use the relative values, e.g., 'large', instead of absolute font sizes, e.g., 12. This approach allows all text sizes to be made larger or smaller based on the font manager's default font size. This class will also accept a fontconfig_ pattern_, if it is the only argument provided. This support does not require fontconfig to be installed. We are merely borrowing its pattern syntax for use here. .. _fontconfig: https://www.freedesktop.org/wiki/Software/fontconfig/ .. _pattern: https://www.freedesktop.org/software/fontconfig/fontconfig-user.html Note that Matplotlib's internal font manager and fontconfig use a different algorithm to lookup fonts, so the results of the same pattern may be different in Matplotlib than in other applications that use fontconfig.

If no good enough match is found, a default font is returned. i6 Nr c C s | j | _|| _|| _tj�td dd�tj�td dd�tj�td dd�g}dD ]b}|tjkrRtj| }|� d�dkr�|� |� d�� qR|� d �dkr�|� |� d �� qR|� |� qRt �d t|�� d d d �| _t|�t� }t|�| _t|dd�tdd� }t|dd�| _d S )N�datapathr r r Z pdfcorefonts)ZTTFPATHZAFMPATH�;r �:zfont search path %sz DejaVu SansZ Helvetica)r r r )� __version__�_version� _FontManager__default_weight� default_sizer, r- r. r r= r� �extendrG r� rX r� rF � defaultFamilyrl r� �ttflist�afmlist)rx rv rs �paths�pathnameZttfpath�ttffiles�afmfilesr r r" ry � s2 � � �zFontManager.__init__r c C s dd� | j D �S )Nc S s g | ] }|j �qS r �r] �r' r� r r r" r) � s z(FontManager.ttffiles.<locals>.<listcomp>)r r{ r r r" r � s zFontManager.ttffilesc C s dd� | j D �S )Nc S s g | ] }|j �qS r r! r" r r r" r) s z(FontManager.afmfiles.<locals>.<listcomp>)r r{ r r r" r s zFontManager.afmfilesc s � fdd�� j �� D �S )Nc s i | ]\}}|� j ||d ��qS )r )r� )r' r( r� r{ r r" � <dictcomp> s � z+FontManager.defaultFont.<locals>.<dictcomp>)r rK r{ r r{ r" � defaultFont s �zFontManager.defaultFontc C s | j S )z1 Return the default font weight. �r r{ r r r" �get_default_weight s z FontManager.get_default_weightc C s t d S )z/ Return the default font size. r� r r r r r" r� s z FontManager.get_default_sizec C s || _ dS )zN Set the default font weight.

Parameters ---------- prop : str or `~matplotlib.font_manager.FontProperties` The font properties to search for. This can be either a `.FontProperties` object or a string defining a `fontconfig patterns`_. fontext : {'ttf', 'afm'}, optional, default: 'ttf' The extension of the font file: - 'ttf': TrueType and OpenType fonts (.ttf, .ttc, .otf) - 'afm': Adobe Font Metrics (.afm) directory : str, optional If given, only search this directory and its subdirectories. fallback_to_default : bool If True, will fallback to the default font family (usually "DejaVu Sans" or "Helvetica") if the first lookup hard-fails. rebuild_if_missing : bool Whether to rebuild the font cache and search again if no match is found. Returns ------- fontfile : str The filename of the best matching font. Notes ----- This performs a nearest neighbor search. Each font is given a similarity score to the target font properties. The first font with the highest score is returned. If no matches below a certain threshold are found, the default font (usually DejaVu Sans) is returned. The result is cached, so subsequent lookups don't have to perform the O(n) nearest neighbor search.
