最为核心的函数详解:WorldCloud函数

wc = WordCloud(background_color="white",random_state =2,scale=1,mask=alice_coloring,stopwords=stopwords,collocations=False, font_path=myfont, width=1400, height=1400, margin=2)

关于WorldCloud函数的简单讲解:

1. background_color来改变背景颜色,只实验了white和black其他未验证.
2. 使用scale来改变词云图像的精细度(数值越大越精细也越耗时;＞8可能要长达数分钟(测试集为10w字的说说)
3. 使用font_path = myfont来改变词云的字体(汉语词云必须依赖自定义的字体库)
4. min_font_size最小字体大小(默认是4)
5. contour_width词云轮廓的描绘,默认是0不描绘
6.关于WorldCloud函数的详解在文章的最后

词云生成的核心代码:

def wordcloud(d,str1,str2):
    alice_coloring = np.array(Image.open(path.join(d,str2)))#背景图片
    stopwords=set(STOPWORDS)
    stopwords.add("said")
    image_colors = ImageColorGenerator(alice_coloring)
    myfont = (r'tyj.ttf') 
    wc = WordCloud(background_color="white",random_state =2,scale=1,mask=alice_coloring,stopwords=stopwords,collocations=False, font_path=myfont, width=1400, height=1400, margin=2)
    txt = open(path.join(d,str1),encoding='utf-8').read()
    txt_jieba = jieba.cut(txt,cut_all = True)
    txt_finish = " ".join(txt_jieba)

    wc.generate(txt_finish)
    plt.imshow(alice_coloring)
    plt.imshow(wc)
    plt.axis("off")
    plt.show()
    wc.to_file(path.join("名称.jpg"))
wordcloud(d,txt,picture

使用说明

纯用户的使用说明

1. 在安装好相应的开发环境和扩展包之后, 并确认你也已经可以成功的运行hello_world.py程序.
   1.1.在此基础上,将全部代码复制粘贴到你的hello_world.py文件中解释并运行.若能出现如下的图片则表示运行成功
   程序解释成功的图片.png
   
   1.2这时候需要将您希望制作的文档和图片放在和.py文件的文件夹中;在txt_input和picture_input中输入你的文档名称和图片名称(名称都需要带.txt和.png,目前只支持这两种格式)
   1.3点击submit并耐心等待1~2min程序给出词云.
   
   程序执行过程中的图.png
   
   
   放大后的图像.png

   1.4关于python小白制作词云,我建议去一下两个网站免费网站:图悦, 收费网站:易词云. 如果你坚持要使用这个程序,并且觉得花费时间是值得的,那我只能说咱们私聊;邮件请发hangyuntang@gmail.com.个人感觉易词云的功能比这个库函数的功能只多不少.

程序员的使用指南

1. 参阅github网站https://github.com/amueller/word_cloud
2. 与我交流hangyuntang@qq.com(只回复技术交流贴,别问我怎么用)

关于WorldCloud函数的详解:

font_path : string

Font path to the font that will be used (OTF or TTF).
Defaults to DroidSansMono path on a Linux machine. If you are on
another OS or don't have this font, you need to adjust this path.
将使用的字体的字体路径（OTF或TTF）。
默认为Linux机器上的DroidSansMono路径。如果你在
另一个操作系统或没有此字体，您需要调整此路径。

width : int (default=400)

Width of the canvas.
画布的宽度 默认是400

height : int (default=200)

Height of the canvas.
画布的高度 默认是200

prefer_horizontal : float (default=0.90)

The ratio of times to try horizontal fitting as opposed to vertical.
If prefer_horizontal < 1, the algorithm will try rotating the word
if it doesn't fit. (There is currently no built-in way to get only
vertical words.)
尝试水平拟合该词(画布中有些词是歪的的始作俑者),＞1就尽量使词语水平;默认0.9.

mask : nd-array or None (default=None)

If not None, gives a binary mask on where to draw words. If mask is not
None, width and height will be ignored and the shape of mask will be
used instead. All white (#FF or #FFFFFF) entries will be considerd
"masked out" while other entries will be free to draw on. [This
changed in the most recent version!]
面具是用来设置词云的底图的,注意透明的底图会无法识别.

contour_width: float (default=0)

If mask is not None and contour_width > 0, draw the mask contour.
如果mask不是none并且contour_width>0会描述词云的轮廓,默认为0不描绘轮廓

contour_color: color value (default="black")

Mask contour color.
轮廓的颜色,默认是黑色

scale : float (default=1)

Scaling between computation and drawing. For large word-cloud images,
using scale instead of larger canvas size is significantly faster, but
might lead to a coarser fit for the words.
精细度设置(越打越精细,速度越慢)

min_font_size : int (default=4)

Smallest font size to use. Will stop when there is no more room in this
size.
最小字体

font_step : int (default=1)

Step size for the font. font_step > 1 might speed up computation but
give a worse fit.
字体增长的步长

max_words : number (default=200)

The maximum number of words.
最大的单词数

stopwords : set of strings or None

The words that will be eliminated. If None, the build-in STOPWORDS
list will be used. Ignored if using generate_from_frequencies.
停用字
字符串集或无将要消除的话。如果为None，则内置STOPWORDS
列表将被使用。如果使用generate_from_frequencies则忽略。
笔者也不知道这玩意儿干什么用的

background_color : color value (default="black")

Background color for the word cloud image.
背景色:默认黑

max_font_size : int or None (default=None)

Maximum font size for the largest word. If None, height of the image is
used.
最大的字体大小

mode : string (default="RGB")

Transparent background will be generated when mode is "RGBA" and background_color is None.
无背景色,模式选择为RGBA时将生成透明背景

relative_scaling : float (default='auto')

Importance of relative word frequencies for font-size. With
relative_scaling=0, only word-ranks are considered. With
relative_scaling=1, a word that is twice as frequent will have twice
the size. If you want to consider the word frequencies and not only
their rank, relative_scaling around .5 often looks good.
If 'auto' it will be set to 0.5 unless repeat is true, in which
case it will be set to 0.
.. versionchanged: 2.0
Default is now 'auto'.
字出现的频率和它尺寸的相关程度。�若为relative_scaling = 0，则只考虑单词排名(单词出现次数与字体大小无关)。
若为relative_scaling = 1，则单词的大小与出现次数全相关。如果你想考虑单词频率而不仅仅是他们的排名，相对于.5左右，通常看起来不错。如果'auto'，它将被设置为0.5，除非repeat为true，其中case它将被设置为0。.. versionchanged：2.0默认现在是“自动”。

color_func : callable, default=None

Callable with parameters word, font_size, position, orientation,
font_path, random_state that returns a PIL color for each word.
Overwrites "colormap".
See colormap for specifying a matplotlib colormap instead.
To create a word cloud with a single color, use
color_func=lambda *args, **kwargs: "white".
The single color can also be specified using RGB code. For example
color_func=lambda *args, **kwargs: (255,0,0) sets color to red.
regexp : string or None (optional)
Regular expression to split the input text into tokens in process_text.
If None is specified, r"\w[\w']+" is used. Ignored if using
generate_from_frequencies.
每个词的色彩映射:
可以使用参数word，font_size，position，orientation，
font_path，random_state，返回每个单词的PIL颜色。覆盖“色彩映射”。
请参阅colormap以指定matplotlib色彩映射。
要创建单色的文字云，请使用color_func = lambda * args，** kwargs：“white”。也可以使用RGB代码指定单色。例如color_func = lambda * args，** kwargs：（255,0,0）将颜色设置为红色。
regexp：string或None（可选）正则表达式将输入文本拆分为process_text中的标记。如果指定None，则使用r“\ w [\ w'] +”。
collocations : bool, default=True
Whether to include collocations
(bigrams) of two words. Ignored if using
generate_from_frequencies.
是否搭配两个字(组成词组),如果使用频率省成法可忽略此项
(笔者猜测是英语的专用形式,汉语应该没啥用)
