Manim配置。

1. ManimConfig

ManimConfig用字典存储了所有配置选项，可以修改配置和获取参数的值，举例：

from manim import *

# 获取选项值
color = config["background_color"]
# 修改默认值
config.background_color = WHITE     # OR
config['background_color'] = WHITE

2. 所有配置选项的默认值

使用Python内置方法vars得到config类所有键值的属性。

for k, v in sorted(vars(config)['_d'].items()):
    print('{}: \t\t\t\t{}'.format(k, v))

再手动稍微归类下，得到如下如果：

3. 一些使用经验

（1）产生视频不能同时将最后一帧保存为图像

出现错误Invalid data found when processing input：

> manim daysofthisyear.py DaysOfThisYear
Manim Community v0.14.0


[01/25/22 16:18:40] INFO     Combining to Movie file.         scene_file_writer.py:608
D:\workspace\manim\media\partial_movie_files\partial_movie_file_list.txt: Invalid data found when processing input

原因是设置了config['save_last_frame'] = True。详情见这里讨论：Using config.save_last_frame = True causes manim 0.6.0 to fail at generating video output. · Issue #1487。

（2）要不要用缓存

Manim默认是使用动画缓存来加快产生视频，但有时候得到的视频并没有更新。可以配置选项，将缓存关掉。

config['disable_caching'] = True
