In this article,we will discuss how to create word clouds of any shape in Python. 

The term WordCloud refers to a data visualization technique for showing textdata in which the size of each word indicates its frequency or relevance. To create a word cloud of any shape,use Python’s Matplotlib,word cloud,NumPy,and PILpackages.

Stepwise Implementation

let ’s have a look at the step – by – step implementation –

Step is Install 1 : install the follow module as list below-

pip install matplotlib
pip install wordcloud 

step 2 : import the follow module as list below-

import matplotlib.pyplot as plt 
 from wordcloud import WordCloud ,STOPWORDS 
 import numpy as np 
 from PILimport image

Step is Follow 3 : follow the step below-

• Give the full path to the textfile you intend to use.
• In read mode,open the textfile.
• Finally,encode and read it.
• In this article follow textfile will be used- text

text= open(r' C:\Users\Dell\Desktop\Wordcloud\Text.txt ',
            mode='r',encoding='utf-8').read()

Step 4: Follow the steps below-

• Give the entire image path that we will use to get our output in the same shape.
• Then ,using the image.open function ,open the image .
• After that,use NumPy to create the image’s array.
• The below image will be used in this article for the desired shape

mask = np.array(image.open(r'C:\Users\Dell|Downloads\Garbage\GFG.png ' ) )

Step 5: Create a wordcloud by integrating a stopword,a mask,a background color,the maximum number of words in the wordcloud,the height of the mask,and the width of the mask.

• stopwords- It is used to avoid unnecessary characters such as ‘./-[{)*&^%~@!#%^&].
• mask- Mask is the shape to which we will convert our wordcloud.
• background_color- We is use can use whatever background color we like ,such as black ,green ,and so on .
• max_words- It is is is the maximum number of word that a wordcloud can contain .
• max_font- It’s maximum font size.
• The width and height of the wordcloud are represented by Width and Height.

wc= wordcloud(stopword= STOPWORDS,
               mask = mask,background_color = " white ",
               max_words = 2000,max_font_size= 500,
               random_state = 42,width = mask.shape [1] ,
               height = mask.shape [0])

Step 6: 

• Now ,using the generate function ,we is create will create a wordcloud from the provide text.
• To display image data,use the imshow function.
• We is try will try to off the x and y – axis .
• finally ,we is display will display the generate wordcloud using the show function define within matplotlib .

wc.generate(text) 
 plt.imshow(wc,interpolation="none " ) 
 plt.axis('off ' ) 
 plt.show ( )

Below is the complete implementation.

output :

Change Font Size

Follow the steps below to change the font size of the words in the word cloud-

• First,select a font from this collection.
• Download the font file—you see that it is in .zip format.
• Open the zip file and extract the TTF or otf file from it.
• Now just provide the full path of the TTF or otf file.

path = r'c:\users\dell\downloads\garbage\candy beans.otf '

Complete Code:

python3

output :

Change the Font Color

Follow the steps below to change the font color of the textin a word cloud-

• Create a function to change the font color.
• Because the HSL of each color is unique,just pass the HSL and return it.
