如何使用mpl.rcParams在matplotlib中加载.ttf文件？ [英] How to load .ttf file in matplotlib using mpl.rcParams?

问题描述

  import matplotlib as mpl 
 import matplotlib.pyplot as plt 
 import matplotlib.font_manager as fm 
 
 mpl.rcParams ['xtick.labelsize'] = 16 
 ... 
  

我已经使用了命令

$ p $ fm.findSystemFonts （）


来获取我的系统上的字体列表。我发现了一个.ttf文件的完整路径，我想使用，

$ p $ '/ usr / share / fonts / truetype / anonymous-pro / Anonymous Pro BI.ttf'


我试过使用这个字体

  mpl.rcParams ['font.family'] ='anonymous-pro'
  

和

  mpl.rcParams ['font.family'] ='匿名Pro BI'
  

  /usr/lib/pymodules/python2.7/matplotlib/font_manager.py:1218：UserWarning：findfont：Font family [ 'anonymous-pro']找不到。回到Bitstream Vera Sans 
  

我可以使用mpl.rcParams字典在我的图中设置这个字体？

编辑

在阅读了更多内容之后，看起来这是确定字体名称的一般问题从一个.ttf文件。这是很容易在Linux或Python？

另外，我试过添加

  mpl.use ['agg'] 
 mpl.rcParams ['text.usetex'] = False 
  

没有任何成功

解决方案

指定一个字体系列：

如果您所知道的是ttf的路径，那么您可以使用 get_name 方法发现字体系列名称：

  import matplotlib as mpl 
 import matplotlib.pyplot as plt 
 import matplotlib.font_manager as font_manager 
 
 path = '/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf'
 prop = font_manager.FontProperties（fname = path）
 mpl.rcParams ['font.family'] = prop.get_name（） 
 fig，ax = plt.subplots（）
 ax.set_title（'Text in a cool font'，size = 40）
 plt.show（）
  
 
 
 $ b 
 按路径指定字体： 
  import matplot lib.pyplot plt 
 import matplotlib.font_manager as font_manager 
 $ b $ path ='/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf'
 prop = font_manager.FontProperties （fname = path）
 fig，ax = plt.subplots（）
 ax.set_title（'cool in font font'，fontproperties = prop，size = 40）
 plt.show ）
  
 
I have a matplotlib script that starts ...  
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

mpl.rcParams['xtick.labelsize']=16 
...
I've used the command 
fm.findSystemFonts()
to get a list of the fonts on my system.  I've discovered the full path to a .ttf file I'd like to use, 
'/usr/share/fonts/truetype/anonymous-pro/Anonymous Pro BI.ttf'
I've tried to use this font without success using the following commands
mpl.rcParams['font.family'] = 'anonymous-pro'  
and
mpl.rcParams['font.family'] = 'Anonymous Pro BI'
which both return something like  
/usr/lib/pymodules/python2.7/matplotlib/font_manager.py:1218: UserWarning: findfont: Font family ['anonymous-pro'] not found. Falling back to Bitstream Vera Sans
Can I use the mpl.rcParams dictionary to set this font in my plots? 

EDIT

After reading a bit more, it seems this is a general problem of determining the font family name from a .ttf file.  Is this easy to do in linux or python ? 

In addition, I've tried adding 
mpl.use['agg']
mpl.rcParams['text.usetex'] = False
without any success 
解决方案
Specifying a font family:

If all you know is the path to the ttf, then you can discover the font family name using the get_name method:
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager

path = '/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf'
prop = font_manager.FontProperties(fname=path)
mpl.rcParams['font.family'] = prop.get_name()
fig, ax = plt.subplots()
ax.set_title('Text in a cool font', size=40)
plt.show()




Specifying a font by path:
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager

path = '/usr/share/fonts/truetype/msttcorefonts/Comic_Sans_MS.ttf'
prop = font_manager.FontProperties(fname=path)
fig, ax = plt.subplots()
ax.set_title('Text in a cool font', fontproperties=prop, size=40)
plt.show()
