查找适用于matplotlib的中文字体名称与实际文件名对应关系的方法
问题来源
如何在matplotlib
中使用中文字体是老问题了,相关文章非常多。
前几天有人问我如何知道中文字体名称和实际文件的对应关系
时,才想起来原来没思考过这个问题,只能让他记住字体与文件的对应关系或者去fonts
目录查看。
难道真的就没有稍微自动化、智能化的查看支持matplotlib
的字体名称与文件的对应关系的方法?
问题解决步骤
matplotlib
与字体相关的模块是font_manager
,观察源码font_manager.py
可知:
1. matplotlib支持哪种类型的字体?
def get_fontext_synonyms(fontext): """ Return a list of file extensions extensions that are synonyms for the given file extension *fileext*. """ return { 'afm': ['afm'], 'otf': ['otf', 'ttc', 'ttf'], 'ttc': ['otf', 'ttc', 'ttf'], 'ttf': ['otf', 'ttc', 'ttf'], }[fontext]
由此可知matplotlib
只支持ttf
和afm
字体。
- ‘ttf': TrueType and OpenType fonts (.ttf, .ttc, .otf)
- ‘afm': Adobe Font Metrics (.afm)
2. matplotlib如何查找系统字体?
findSystemFonts
模块函数的作用是查找系统字体。
def findSystemFonts(fontpaths=None, fontext='ttf'): -->list
参数fontext
默认值为'ttf'
,另外还支持值'afm'
。
参数fontpaths
默认值是None
。
对于fontpaths
有两种种情况。
fontpaths
为None
函数会判断操作系统,如果是Windows,调用函数win32InstalledFonts
,如果不是Windows,调用函数get_fontconfig_fonts
。
对于Windows,函数win32InstalledFonts
到以下路径查找。
# OS Font paths MSFolders = \ r'Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders' MSFontDirectories = [ r'SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts', r'SOFTWARE\Microsoft\Windows\CurrentVersion\Fonts'] MSUserFontDirectories = [ str(Path.home() / 'AppData/Local/Microsoft/Windows/Fonts'), str(Path.home() / 'AppData/Roaming/Microsoft/Windows/Fonts'), ]
对于非Windows
操作系统,函数get_fontconfig_fonts
主要依托fontconfig
包(即fc-list
命令)查找字体,要求fontconfig>=2.7
。
fontpaths
不为None
当fontpaths
不为None
时,通过list_fonts()
函数查找字体。
list_fonts()
函数其实一个通用的按路径、扩展名递归遍历文件路径的函数。
def list_fonts(directory, extensions): """ Return a list of all fonts matching any of the extensions, found recursively under the directory. """ extensions = ["." + ext for ext in extensions] return [os.path.join(dirpath, filename) # os.walk ignores access errors, unlike Path.glob. for dirpath, _, filenames in os.walk(directory) for filename in filenames if Path(filename).suffix.lower() in extensions]
3.matplotlib如何查找matplotlib自带字体?
安装matplotlib
时,会在site-packages\matplotlib\mpl-data\fonts
目录放置一系列字体。
通过源码可知fonts
目录下有'ttf', 'afm', 'pdfcorefonts'
3个子目录。
paths = [cbook._get_data_path('fonts', subdir) for subdir in ['ttf', 'afm', 'pdfcorefonts']]
In [1]: import matplotlib.cbook as cbook In [2]: paths = [cbook._get_data_path('fonts', subdir) for subdir in ['ttf', 'afm', 'pdfcorefonts']] In [3]: paths Out[4]: [WindowsPath('c:/users/administrator/appdata/local/programs/python/python37/lib/site-packages/matplotlib/mpl-data/fonts/ttf'), WindowsPath('c:/users/administrator/appdata/local/programs/python/python37/lib/site-packages/matplotlib/mpl-data/fonts/afm'), WindowsPath('c:/users/administrator/appdata/local/programs/python/python37/lib/site-packages/matplotlib/mpl-data/fonts/pdfcorefonts')]
4.matplotlib如何生成字体列表?
FontManager
类是matplotlib
管理字体的重要类,是一个单例类。FontManager
实例在构造后会创建一个ttf
字体列表和一个afm
字体列表,并会缓存他们的字体属性。
下面简单看看ttflist
、afmlist
列表的元素的属性。
In [1]: import matplotlib.font_manager as mf In [2]: ttflist=mf.FontManager().ttflist In [3]: vars(ttflist[0]) Out[3]: {'fname': 'c:\\users\\administrator\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\matplotlib\\mpl-data\\fonts\\ttf\\DejaVuSansMono-BoldOblique.ttf', 'name': 'DejaVu Sans Mono', 'style': 'oblique', 'variant': 'normal', 'weight': 700, 'stretch': 'normal', 'size': 'scalable'} In [4]: len(ttflist) Out[4]: 252 In [5]: afmlist=mf.FontManager().afmlist In [6]: vars(afmlist[0]) Out[6]: {'fname': 'c:\\users\\administrator\\appdata\\local\\programs\\python\\python37\\lib\\site-packages\\matplotlib\\mpl-data\\fonts\\afm\\pagko8a.afm', 'name': 'ITC Avant Garde Gothic', 'style': 'italic', 'variant': 'normal', 'weight': 'book', 'stretch': 'normal', 'size': 'scalable'} In [7]: len(afmlist) Out[7]: 60
5.matplotlib的字体属性缓存在哪里?
前面了解到matplotlib
会缓存字体属性那在什么位置呢?
根据源码可知,字体缓存的所在目录是.matplotlib
,缓存文件是fontlist-v330.json
(文件名与版本有关)。在某些老版本的matplotlib
中字体缓存文件名是fontList.cache
。
_fmcache = os.path.join( mpl.get_cachedir(), 'fontlist-v{}.json'.format(FontManager.__version__))
In [1]: import matplotlib In [2]: matplotlib.get_cachedir() Out[2]: 'C:\\Users\\Administrator\\.matplotlib'
6. 怎么知道哪些字体是中文字体?
虽然在前面已经知道matplotlib
会把系统字体和自带字体信息存放在ttflist
和afmlist
中,但是在这些字体信息中也不容易确定哪些是中文字体。
通过资料查找有3种方法:
查看Windows的fonts
系统目录中显示的字体名称和文件名属性。这种方法效率太低!
通过注册表项[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
查看字体名和字体文件名称映射。这种方法一些系统字体仍然看不到汉字名称。
根据第1种方法想到了去查字体文件的元数据,Python相关的库有两个:fonttools
,作者是老爹Guido的弟弟Just van Rossum
;TTFQuery
,基于fonttools
的TTF包,只能查看TTF
文件而且最后更新日期是2012年。
TTFQery

源码中有些小问题,源码不算复杂,直接修改。
